Abstract
Special pathogens are broadly defined as highly transmissible organisms capable of causing severe disease in humans. Children's hospital healthcare personnel (HCP) should be prepared to identify patients possibly infected with a special pathogen, isolate the patient to minimize transmission, and inform key infection prevention, clinical, and public health stakeholders. Effective preparedness requires resources and practice with attention to education, policies and procedures, drills and training, and supplies. Successfully preparing for special pathogens is an important measure toward keeping communities, HCP, and patients and families safe in this global age that brings pathogens from across the world to our doorstep.

Abstract
Nanobodies, single-domain antibodies derived from variable domain of camelid or shark heavy-chain antibodies, have unique properties with small size, strong binding affinity, easy construction in versatile formats, high neutralizing activity, protective efficacy, and manufactural capacity on a large-scale. Nanobodies have been arisen as an effective research tool for development of nanobiotechnologies with a variety of applications. Three highly pathogenic coronaviruses (CoVs), SARS-CoV-2, SARS-CoV, and MERS-CoV, have caused serious outbreaks or a global pandemic, and continue to post a threat to public health worldwide. The viral spike (S) protein and its cognate receptor-binding domain (RBD), which initiate viral entry and play a critical role in virus pathogenesis, are important therapeutic targets. This review describes pathogenic human CoVs, including viral structures and proteins, and S protein-mediated viral entry process. It also summarizes recent advances in development of nanobodies targeting these CoVs, focusing on those targeting the S protein and RBD. Finally, we discuss potential strategies to improve the efficacy of nanobodies against emerging SARS-CoV-2 variants and other CoVs with pandemic potential. It will provide important information for rational design and evaluation of therapeutic agents against emerging and reemerging pathogens.

Virus Res 2023; 334:199156.

Abstract
Middle East respiratory syndrome coronavirus (MERS-CoV), a highly pathogenic coronavirus in the same Betacoronavirus genus and Coronaviridae family as SARS-CoV-2, continues to post a threat to human health. Mortality remains high; therefore, there is a need to develop effective vaccines to prevent MERS-CoV infection. The receptor-binding domain (RBD) within the MERS-CoV spike (S) protein is a critical vaccine target. The latest mRNA technology has enabled rapid development of much-needed vaccines with high efficiency and scalable manufacturing capacity. Here, we designed a mRNA vaccine encoding the RBD of MERS-CoV S protein (RBD-mRNA) and evaluated its immunogenicity and protective efficacy in a mouse model. The data showed that nucleoside-modified RBD-mRNA, but not RBD-mRNA lacking the nucleoside modification, was stable and elicited broadly and durable neutralizing antibody and cellular immune responses, which neutralized the original strain and multiple MERS-CoV variants. Among all immunization routes tested, the intradermal route was appropriate for this RBD-mRNA to induce strong B-cell responses and the highest neutralizing antibody titers. Importantly, injection of nucleoside-modified RBD-mRNA through the intradermal route protected immunized mice against challenge with MERS-CoV. This protection correlated with serum neutralizing antibody titers. Overall, we have developed an effective MERS-CoV RBD-based mRNA vaccine (with potential for further development) that prevents infection by divergent strains of MERS-CoV.

Abstract
In this paper, we present a new fractional epidemiological model on a heterogeneous network to investigate Middle East respiratory syndrome (MERS-CoV), which is caused by a virus in the coronavirus family. We also consider the development of equations for the camel population, given that it is the primary animal source of the virus, as well as direct human interaction with this population. The model is configured in an SIS form for both the human population and the camel population. We study the equilibrium positions of the system and the conditions for the existence of each of them, as well as the local stability of each equilibrium position. Then, we provide some numerical examples that compare real data and numerical results.

Gilbert GL, Kerridge I. What is needed to sustain improvements in hospital practices post-COVID-19? a qualitative study of interprofessional dissonance in hospital infection prevention and control. BMC Health Serv Res 2022; 22:504.

Abstract
Background Hospital infection prevention and control (IPC) depends on consistent practice to achieve its purpose. Standard precautions are embedded in modern healthcare policies, but not uniformly observed by all clinicians. Well-documented differences in attitudes to IPC, between doctors and nurses, contribute to suboptimal IPC practices and persistence of preventable healthcare-associated infections. The COVID-19 pandemic has seriously affected healthcare professionals’ work-practices, lives and health and increased awareness and observance of IPC. Successful transition of health services to a ‘post-COVID-19’ future, will depend on sustainable integration of lessons learnt into routine practice. Methods The aim of this pre-COVID-19 qualitative study was to investigate factors influencing doctors’ IPC attitudes and practices, whether they differ from those of nurses and, if so, how this affects interprofessional relationships. We hypothesised that better understanding would guide new strategies to achieve more effective IPC. We interviewed 26 senior clinicians (16 doctors and 10 nurses) from a range of specialties, at a large Australian tertiary hospital. Interview transcripts were reviewed iteratively, and themes identified inductively, using reflexive thematic analysis. Results Participants from both professions painted clichéd portraits of ‘typical’ doctors and nurses and recounted unflattering anecdotes of their IPC behaviours. Doctors were described as self-directed and often unaware or disdainful of IPC rules; while nurses were portrayed as slavishly following rules, ostensibly to protect patients, irrespective of risk or evidence. Many participants believed that doctors object to being reminded of IPC requirements by nurses, despite many senior doctors having limited knowledge of correct IPC practice. Overall, participants’ comments suggested that the ‘doctor-nurse game’—described in the 1960s, to exemplify the complex power disparity between professions—is still in play, despite changes in both professions, in the interim. Conclusions The results suggest that interprofessional differences and inconsistencies constrain IPC practice improvement. IPC inconsistencies and failures can be catastrophic, but the common threat of COVID-19 has promoted focus and unity. Appropriate implementation of IPC policies should be context-specific and respect the needs and expertise of all stakeholders. We propose an ethical framework to guide interprofessional collaboration in establishing a path towards sustained improvements in IPC and bio-preparedness.

Abstract
BACKGROUND Uncertainties surrounding the 2019 novel coronavirus (COVID-19) remain a major global health challenge and requires attention. Researchers and medical experts have made remarkable efforts to reduce the number of cases and prevent future outbreaks through vaccines and other measures. However, there is little evidence on how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection entropy can be applied in predicting the possible number of infections and deaths. In addition, more studies on how the COVID-19 infection density contributes to the rise in infections are needed. This study demonstrates how the SARS-COV-2 daily infection entropy can be applied in predicting the number of infections within a given period. In addition, the infection density within a given population attributes to an increase in the number of COVID-19 cases and, consequently, the new variants. RESULTS Using the COVID-19 initial data reported by Johns Hopkins University, World Health Organization (WHO) and Global Initiative on Sharing All Influenza Data (GISAID), the result shows that the original SAR-COV-2 strain has R0<1 with an initial infection growth rate entropy of 9.11 bits for the United States (U.S.). At close proximity, the average infection time for an infected individual to infect others within a susceptible population is approximately 7 minutes. Assuming no vaccines were available, in the U.S., the number of infections could range between 41,220,199 and 82,440,398 in late March 2022 with approximately, 1,211,036 deaths. However, with the available vaccines, nearly 48 Million COVID-19 cases and 706, 437 deaths have been prevented. CONCLUSION The proposed technique will contribute to the ongoing investigation of the COVID-19 pandemic and a blueprint to address the uncertainties surrounding the pandemic.

Abstract
OBJECTIVE This study aimed to assess the protective measures among health-care workers (HCWs) in a war-torn area during coronavirus disease 2019 (COVID-19) pandemic. METHODS An online cross-sectional questionnaire was administrated to HCWs in Syria between April 1 and May 21, 2020. The questions aimed to assess the HCWs' application of safety, hygiene, and necessary protection considerations while attending to suspected or proven COVID-19 cases. Unpaired t-test and 1-way analysis of variance (ANOVA) were used for statistical analysis. RESULTS Of the 290 participants included in the statistical analysis, 250 were medical doctors. Low scores of protective practices were noticed among the participants, as only 12% of doctors had a score above 6/15 points, and only 37.5% of nurses had a score of more than 4/12 points. Medical doctors who were not on the frontlines scored significantly higher than those who were on the frontlines (4.69 vs 3.80 points, respectively; P < 0.001). CONCLUSIONS More courses and training sessions should be implemented to improve the practice of protective measures among HCWs (frontliners in particular) in areas with fragile health systems, such as Syria, during the COVID-19 pandemic, especially those on the frontlines. Moreover, specific COVID-19 protection measures guidelines to low-income countries are needed.

Abstract
For survivors of the COVID-19 disease, defeating the virus is just the beginning of a long road to recovery. The virus’s inducibility and catastrophic effects are distributed in multiple organs. The induction of cytokine storms in COVID-19 patients is due to the interaction of the SARS-CoV-2 virus and the host receptor, leading to various immunopathological consequences that might eventually lead to death. So far, it has hit tons of people across the world, but there is still no effective treatment. Patients facing the complications of COVID-19 after recovering have shown extensive clinical symptoms similar to previously circulating coronaviruses. Previous knowledge, and literature have opened up ways to treat this disease and manage post-COVID-19 complications, which poses a severe challenge to health system globally and may exacerbate the fragmentation of diseases. The use of steroids, as a treatment, showed various health problems and side-effects in COVID-19 patients. This review substantially discusses various post-COVID-19 complications observed, adjunctive therapies used along with common COVID-19treatment and spotlighted their side effects and consequences. This review provides latest literature on COVID-19 which emphasizes the subsequent complications in various organs, side-effects of drug, and alternative regimes that were used to treat COVID-19.

Abstract
Parkinson's disease (PD) is one of the most common age-related disorders globally. The pathophysiological mechanisms and precipitating factors underlying PD manifestations, including genetic and environmental parameters, inflammation/stress and ageing, remain elusive. Speculations about whether the Coronavirus Disease 2019 (Covid-19) pandemic could be a pivotal factor in affecting the prevalence and severity of PD or triggering a wave of new-onset parkinsonism in both the near and distant future have recently become very popular, with researchers wondering if there is a changing trend in current parkinsonism cases. Could the current understanding of the Covid-19 pathophysiology provide clues for an impending rise of parkinsonism cases in the future? Are there any lessons to learn from previous pandemics? Our aim was to look into these questions and available current literature in order to investigate if Covid-19 could constitute a cardinal event affecting the parkinsonism landscape.

Abstract
In recent past, major pandemics and epidemics have occurred due to the emergence and resurgence of the novel strains of viruses like Influenza [HINI-A "Spanish Flu", H1N1-Novel A "Swine flu"], Corona [Middle East Respiratory Syndrome (MERS), Severe acute respiratory syndrome (SARS-CoV-1, SARS-CoV-2)] and Ebola virus [Ebola virus disease]. These infectious diseases may have several ocular manifestations and rarely might be the presenting symptom of the underlying disease. The eyes can act as a portal of entry and/or route of viral transmission for these pathogens. Therefore, an ophthalmologist/optometrist needs to act with ample preparedness and responsibility. Establishing a standard of care in ophthalmic practice by modifying the conventional examination techniques and adopting tele-ophthalmology model to triage the patients can control the community spread of the disease. This article aims to elucidate the ocular manifestations in these pandemics and measures that should be adopted in ophthalmic practice to prevent the disease transmission.

Abstract
BACKGROUND Exposure to coronavirus disease 2019 (COVID-19) can cause severe mental health problems, the dynamics of which remain unclear. This study evaluated the mental status of frontline health care workers (FHWs) and suspected infected patients (SIPs) during different periods of the COVID-19 outbreak. MATERIALS AND METHODS Demographic and psychological data were collected through a cross-sectional survey of 409 participants in a hospital from 20 January to 7 August 2020. COVID-19 outbreaks were divided into three periods owing to the time, place, and scale, including the national outbreak period (a nationwide pandemic period from 20 January to 8 April 2020), sporadic period (a stable period from 9 April to 10 June), and local epidemic period (a local pandemic in Beijing from 11 June to 7 August 2020). Acute psychological disorders (APDs), including symptoms of anxiety and depression, were assessed using the Zung Self-Rating Anxiety/Depression Scale (SAS/SDS). RESULTS A total of 206 FHWs and 203 SIPs completed the electronic questionnaire. Overall, the prevalence rates of anxiety and depression among SIPs were 3.9 and 19.4%, respectively, while significantly higher prevalence rates (17.7 and 25.1%) were found among FHWs, P-value < 0.05. Psychological status among SIPs did not differ significantly across the three periods. The FHWs were more vulnerable, as their SAS and SDS scores and almost all the dimension scores were significantly higher during the local epidemic period than during the national outbreak and sporadic periods (all P-values < 0.001). The prevalence of anxiety (34.41%) and depression (41.94%) was significantly higher during the local epidemic period (P < 0.001). Logistic and linear mixed models showed that age, sex, and doctor-patient ratio especially, independently influenced most dimension scores of SAS and SDS among FHWs (P < 0.05). CONCLUSION Compared to the COVID-19 epidemic at the national level, the local epidemic had a greater influence on FHWs' mental health. More attention should be given to the workload of FHWs.

ACS OMEGA 2021; 6:32072-32080. [PMID: 34870028 PMCID: PMC8638009 DOI: 10.1021/acsomega.1c04849] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Accepted: 10/15/2021] [Indexed: 05/28/2023]
Abstract
The miniaturization of biosensors for point-of-care diagnosis is highly important in infection control. Electrochemical biosensors offer several advantages in diagnosis in terms of cost, disposability, portability, and sensitivity. Here, a miniaturized electrochemical immunosensor combined with cotton fiber for the detection of the Middle-East respiratory syndrome coronavirus (MERS-CoV) is described. Taking advantage of the absorption capability of cotton, the nasal and saliva samples can be collected and directly transferred to the immunosensor surface for detection using a single tool. The immunosensor was fabricated on a disposable screen-printed electrode precoated with carbon nanofibers. The electrodes were functionalized with carboxyphenyl groups that were used for the immobilization of the spike protein of the MERS-CoV. A competitive detection scheme was employed using the antibody for the MERS-CoV spike protein, and the square-wave voltammetry technique was used for measurements. The biosensor tested after the cotton coating of the electrode exhibited excellent performance. The biosensor was capable of detecting the MERS-CoV spike protein within a concentration range from 0.1 pg·mL-1 to 1 μg·mL-1 with a limit of detection of 0.07 pg·mL, implying the high sensitivity of the method. The immunosensor did not exhibit any cross-reactivity against proteins from HCoV and Influenza A, indicating the excellent selectivity of this approach. Testing of the biosensor in nasal samples showed very high recovery percentages. This disposable biosensor can be used as a miniaturized device for the collection of samples and detection of the virus using a portable potentiostat connected to a smartphone.

Diagnostics (Basel) 2021; 11:2083. [PMID: 34829430 PMCID: PMC8625106 DOI: 10.3390/diagnostics11112083] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Revised: 10/26/2021] [Accepted: 11/05/2021] [Indexed: 12/15/2022] Open
Abstract
The design and development of biosensors, analytical devices used to detect various analytes in different matrices, has emerged. Biosensors indicate a biorecognition element with a physicochemical analyzer or detector, i.e., a transducer. In the present scenario, various types of biosensors have been deployed in healthcare and clinical research, for instance, biosensors for blood glucose monitoring. Pathogenic microbes are contributing mediators of numerous infectious diseases that are becoming extremely serious worldwide. The recent outbreak of COVID-19 is one of the most recent examples of such communal and deadly diseases. In efforts to work towards the efficacious treatment of pathogenic viral contagions, a fast and precise detection method is of the utmost importance in biomedical and healthcare sectors for early diagnostics and timely countermeasures. Among various available sensor systems, optical biosensors offer easy-to-use, fast, portable, handy, multiplexed, direct, real-time, and inexpensive diagnosis with the added advantages of specificity and sensitivity. Many progressive concepts and extremely multidisciplinary approaches, including microelectronics, microelectromechanical systems (MEMSs), nanotechnologies, molecular biology, and biotechnology with chemistry, are used to operate optical biosensors. A portable and handheld optical biosensing device would provide fast and reliable results for the identification and quantitation of pathogenic virus particles in each sample. In the modern day, the integration of intelligent nanomaterials in the developed devices provides much more sensitive and highly advanced sensors that may produce the results in no time and eventually help clinicians and doctors enormously. This review accentuates the existing challenges engaged in converting laboratory research to real-world device applications and optical diagnostics methods for virus infections. The review's background and progress are expected to be insightful to the researchers in the sensor field and facilitate the design and fabrication of optical sensors for life-threatening viruses with broader applicability to any desired pathogens.

Abstract
Objective:
To investigate the level of awareness of ophthalmologists towards COVID-19 and their perceptions towards infection control in ophthalmic practice.
Methods:
A web-based survey was conducted using Google Forms during the month of December 2020. All ophthalmologists practicing in Sudan were invited to participate in the study. Participants who did not agree to the terms of the electronic consent form presented at the beginning of the questionnaire as well as those who did not complete the survey, were excluded from the analysis. Knowledge of causes, symptoms, and methods of transmission of COVID-19; ophthalmologists’ attitudes and perceptions towards COVID-19 and clinical practice, including contact lens practice, were assessed using a set of 26 multiple-choice close-ended questions.
Results:
Of the 307 participants, 77.4% were in the age range 30-40 years and 73% were contact lens practitioners. While 96.1% acknowledged the scientific name of COVID-19, 46.9% were aware of its cause. Ophthalmologists aged 40-50 years were more likely to agree that air-puffing tonometer risks infection spread (OR 1.62, 95% CI: 0.27-9.70, p<0.01). Ophthalmologists aged 30-40 years were more likely to agree that a slit lamp shield would reduce infection risk (OR 1.52, 95% CI: 0.33-6.96, p<0.01). Contact lens practitioners were more likely to perceive that frequent replacement contact lens use can increase the infection spread (OR 2.64, 95% CI: 1.17-5.94, p<0.01).
Conclusion:
Ophthalmologists in Sudan demonstrated a mixed level of knowledge of the causes, symptoms, and modes of transmission of COVID-19. While the majority were able to identify the protective measures generally required by medical practitioners and patients, there was a limited level of knowledge regarding protective measures specific to ophthalmic practices, especially when dealing with contact lenses. Official national guidelines about safe ophthalmic service provision during the COVID-19 pandemic are recommended.

Risk factors associated with severe hospital burden of COVID-19 disease in Regione Lombardia: a cohort study. BMC Infect Dis 2021; 21:1041. [PMID: 34620121 PMCID: PMC8496148 DOI: 10.1186/s12879-021-06750-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Accepted: 09/24/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Understanding the risk factors associated with hospital burden of COVID-19 is crucial for healthcare planning for any future waves of infection. METHODS An observational cohort study is performed, using data on all PCR-confirmed cases of COVID-19 in Regione Lombardia, Italy, during the first wave of infection from February-June 2020. A multi-state modelling approach is used to simultaneously estimate risks of progression through hospital to final outcomes of either death or discharge, by pathway (via critical care or not) and the times to final events (lengths of stay). Logistic and time-to-event regressions are used to quantify the association of patient and population characteristics with the risks of hospital outcomes and lengths of stay respectively. RESULTS Risks of severe outcomes such as ICU admission and mortality have decreased with month of admission (for example, the odds ratio of ICU admission in June vs March is 0.247 [0.120-0.508]) and increased with age (odds ratio of ICU admission in 45-65 vs 65 + age group is 0.286 [0.201-0.406]). Care home residents aged 65 + are associated with increased risk of hospital mortality and decreased risk of ICU admission. Being a healthcare worker appears to have a protective association with mortality risk (odds ratio of ICU mortality is 0.254 [0.143-0.453] relative to non-healthcare workers) and length of stay. Lengths of stay decrease with month of admission for survivors, but do not appear to vary with month for non-survivors. CONCLUSIONS Improvements in clinical knowledge, treatment, patient and hospital management and public health surveillance, together with the waning of the first wave after the first lockdown, are hypothesised to have contributed to the reduced risks and lengths of stay over time.

Abstract
Background Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19 pandemic, has infected more than 179 million people worldwide. Testing of infected individuals is crucial for identification and isolation, thereby preventing further spread of the disease. Presently, Taqman™ Reverse Transcription Real Time PCR is considered gold standard, and is the most common technique used for molecular testing of COVID-19, though it requires sophisticated equipments, expertise and is also relatively expensive. Objective Development and optimization of an alternate molecular testing method for the diagnosis of COVID-19, through a two step Reverse Transcription Loop-mediated isothermal AMPlification (RT-LAMP). Results Primers for LAMP were carefully designed for discrimination from other closely related human pathogenic coronaviruses. Care was also taken that primer binding sites are present in conserved regions of SARS-CoV2. Our analysis shows that the primer binding sites are well conserved in all the variants of concern (VOC) and variants of interest (VOI), notified by World Health Organization (WHO). These lineages include B.1.1.7, B.1.351, P.1, B.1.617.2, B.1.427/B.1.429, P.2, B.1.525, P.3, B.1.526 and B.1.617.1. Various DNA polymerases with strand displacement activity were evaluated and conditions were optimized for LAMP amplification and visualization. Different LAMP primer sets were also evaluated using synthetic templates as well as patient samples. Conclusion In a double blind study, the RT-LAMP assay was validated on more than 150 patient samples at two different sites. The RT-LAMP assay appeared to be 89.2% accurate when compared to the Taqman™ rt-RT-PCR assay.

Abstract
The article reviews international and Russian scientific papers concerning the possibility of transmitting coronavirus infections, particularly the COVID-19, through eye surface. According to the studied literature, the incidence of ocular symptoms in COVID-19 is around 0.8-31.6%, with conjunctivitis being the most frequent manifestation. The review summarizes data on virus detection in conjunctival discharge of COVID-19 patients. Across six studies, the total number of patients is 252, among which were 8 cases (3.17%) of virus detection in the conjunctival cavity. The review discusses the reasons for infrequent detection of the virus in the lacrimal fluid. The analyzed data shows that COVID-19 associated conjunctivitis can be the first symptom, the primary manifestation, or sometimes be detected in the lacrimal fluid of patients without any concomitant signs of eye surface inflammation. The article also presents two clinical cases of patients with keratoconjunctivitis and conjunctivitis associated with COVID-19, as well as the results of experimental transconjunctival and respiratory exposure of Rhesus macaques to SARS-CoV-2 with conclusion of possibility of this type of transmission. Additionally, the review contains the opinion of researchers concerning the influence of several factors on the possibility of virus detection in the lacrimal fluid. The conclusion was made that there is possibility of COVID-19 transmission through the eye surface. While it is not being considered a major transmission route, it should not be ignored. Conjunctival cavity of COVID-19 patients can be the source of infection. Eye protection measures should be undertaken when working with potentially infected patients.

Abstract
Background: Nowadays, we are facing a disease caused by SARS-CoV- 2, known globally as COVID-19, which is considered a threat to global health due to its high contagiousness and rapid spread. Methods: Analytical cross-sectional study in 302 health professionals. An online questionnaire consisting of questions about knowledge, attitudes and practices (KAP) towards COVID-19 was applied. Socio- demographic, occupational and comorbidities factors were explored. Simple and multiple logistic regression models were used to identify factors associated with KAP. Results: Of the total, 25.2%, 31.5% and 37.4% had high levels of knowledge, preventive practices and risk perception attitudes respectively. Being married aOR=6.75 CI(1.46-31.2) p=0.014, having a master's degree aOR=0.4, CI(0.21-0.80) p=0.009, having a working day with less than ten hours ORa=0.49 CI(0.25-0.95) p=0.036 and obesity aOR=0.38 CI (0.15-0.95) p=0.039 were associated with a low level of knowledge of COVID-19. The variables associated with preventive practices were being over the age of 50 aOR=0.52 CI(0.27-0.98) p=0.007, working in the hospitalization area aOR=1.86 CI(1.08-3.18) p= 0.018 and having comorbidities such as arterial hypertension aOR=0.28 CI(0.081-0.99) p=0.02 and obesity aOR=0.35 CI(0.14-0.83) p=0.019. In relation to negative attitudes towards COVID-19, it was found that physical contact with patients with a confirmed diagnosis aOR=1.84 CI (1.14-2.97) p=0.006 and having asthma aOR=2.13 CI(1.081-4.22) p=0.029 were associated with these attitudes. Conclusion: Our study revealed that health professionals have an insufficient level of knowledge of COVID-19. This is why we recommend implementing strategies such as health literacy programs among health care workers. Thus, they can help develop positive.

The variables associated with preventive practices were being over the age of 50 aOR=0.52 IC(0.27-0.98) p=0.007, working in the hospitalization area aOR=1.86 IC(1.08-3.18) p= 0.018 and having comorbidities such as arterial hypertension aOR=0.28 IC(0.081-0.99) p=0.02 and obesity aOR=0.35 IC(0.14-0.83) p=0.019. In relation to negative attitudes towards COVID-19, it was found that physical contact with patients with a confirmed diagnosis aOR=1.84 IC (1.14-2.97) p=0.006 and having asthma aOR=2.13 IC(1.081-4.22) p=0.029 were associated with these attitudes. Conclusion: Our study revealed that health professionals have an insufficient level of knowledge of COVID-19. This is why we recommend implementing strategies such as health literacy programs among health care workers. Thus, they can help develop positive attitudes towards the acquisition of self-care habits at work that, in turn, improve their confidence so that health care workers can provide adequate care for their patients and protect themselves.

Abstract
Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-1) and Middle East Respiratory Syndrome Coronavirus (MERS-CoV) infections, like most other viruses that affect the respiratory tract can cause severe maternal illness and adverse pregnancy outcomes. They are not only highly transmissible (acquired through droplets), but Host reservoirs such as dromedary camels for MERS-CoV and masked palm civet for SARS-CoV-1 are critical links in the onset of outbreaks. Clinically they present with flu-like symptoms and therefore a high index of suspicion is required to ensure timely diagnosis and tailored management. Although there are not many reported series on these infections in pregnancy they seem to be associated with an increased risk of preterm delivery and maternal mortality. Diagnosis is made by PCR from nasopharyngeal swabs. There are currently no effective anti-viral agents for these viruses but following infections various agents have been administered to patients. The most important aspect of management should be early identification of deterioration and intensive support and prevention of transmission. Our understanding of the evidence of the impact of both infections on pregnancies suggests the potential for future repeat outbreaks, hence the importance of maintaining vigilance across healthcare systems.

Abstract
Recently, the potential dangers of viral infection transmission through water and air have become the focus of worldwide attention, via the spread of COVID-19 pandemic. The occurrence of large-scale outbreaks of dangerous infections caused by unknown pathogens and the isolation of new pandemic strains require the development of improved methods of viruses' inactivation. Viruses are not stable self-sustaining living organisms and are rapidly inactivated on isolated surfaces. However, water resources and air can participate in the pathogens' diffusion, stabilization, and transmission. Viruses inactivation and elimination by adsorption are relevant since they can represent an effective and low-cost method to treat fluids, and hence limit the spread of pathogen agents. This review analyzed the interaction between viruses and carbon-based, oxide-based, porous materials and biological materials (e.g., sulfated polysaccharides and cyclodextrins). It will be shown that these adsorbents can play a relevant role in the viruses removal where water and air purification mostly occurring via electrostatic interactions. However, a clear systematic vision of the correlation between the surface potential and the adsorption capacity of the different filters is still lacking and should be provided to achieve a better comprehension of the global phenomenon. The rationalization of the adsorption capacity may be achieved through a proper physico-chemical characterization of new adsorbents, including molecular modeling and simulations, also considering the adsorption of virus-like particles on their surface. As a most timely perspective, the results on this review present potential solutions to investigate coronaviruses and specifically SARS-CoV-2, responsible of the COVID-19 pandemic, whose spread can be limited by the efficient disinfection and purification of closed-spaces air and urban waters.

Abstract
End 2019, the zoonotic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), named COVID-19 for coronavirus disease 2019, is the third adaptation of a contagious virus following the severe acute respiratory syndrome coronavirus in 2002, SARS-CoV, and the Middle East respiratory syndrome virus in 2012, MERS-CoV. COVID-19 is highly infectious and virulent compared to previous outbreaks. We review sources, contagious routes, preventive measures, pandemic, outbreak, epidemiology of SARS-CoV, MERS-CoV and SARS-CoV-2 from 2002 to 2020 using a Medline search. We discuss the chronology of the three coronaviruses, the vulnerability of healthcare workers, coronaviruses on surface and in wastewater, diagnostics and cures, and measures to prevent spreading.

Abstract
Viruses have caused significant damage to the world. Effective detection is required to relieve the impact of viral infections. A biomolecule can be used as a template such as deoxyribonucleic acid (DNA), peptide, or protein, for the growth of silver nanoclusters (AgNCs) and for recognizing a virus. Both the AgNCs and the recognition elements are tunable, which is promising for the analysis of new viruses. Considering that a new virus such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) urgently requires a facile sensing strategy, various virus detection strategies based on AgNCs including fluorescence enhancement, color change, quenching, and recovery are summarized. Particular emphasis is placed on the molecular analysis of viruses using DNA stabilized AgNCs (DNA-AgNCs), which detect the virus's genetic material. The more widespread applications of AgNCs for general virus detection are also discussed. Further development of these technologies may address the challenge for facile detection of SARS-CoV-2.

Abstract
During the COVID‐19 pandemic, health care workers (HCWs) have been lauded as heroes, yet both before and during the pandemic, they lacked the protections needed to keep them safe. We summarize data on HCW infections and deaths during previous epidemics, the costs of the failure to protect them, and provide recommendations for strengthening HCW protections by investments in and implementation of infection prevention and control and water, sanitation, and hygiene programs, training and career development, and national and global monitoring of HCW infections. We must move from placing individuals at undue risk to accepting collective responsibility and accountability for the well‐being of our HCWs and take concrete actions to protect HCWs who risk their lives to protect patients and populations.

Abstract
BACKGROUND The COVID-19 pandemic has focused attention on the challenges and risks faced by frontline healthcare workers (HCW). This study aimed to describe the clinical outcomes and risk factors for SARS-CoV-2 infection in HCW. METHODS Three databases were surveyed and 328 articles were identified. Of these, 225 articles did not meet inclusion criteria; therefore, 97 full-text article were reviewed. Finally, after further revision, 30 articles were included in the systematic review and 28 were used for meta-analysis. RESULTS Twenty-eight studies were identified involving 119,883 patients. The mean age of the patients was 38.37 years (95% CI 36.72-40.03) and males comprised 21.4% (95% CI 12.4-34.2) of the population of HCW. The percentage of HCW who tested positive for COVID-19 was 51.7% (95% CI 34.7-68.2). The total prevalence of comorbidities in seven studies was 18.4% (95% CI 15.5-21.7). The most prevalent symptoms were fever 27.5% (95% CI 17.6-40.3) and cough 26.1% (95% CI 18.1-36). The prevalence of hospitalisation was 15.1% (95% CI 5.6-35) in 13 studies and of death was 1.5% (95% CI 0.5-3.9) in 12 studies. Comparisons of HCW with and without infection showed an increased relative risk for COVID-19 related to personal protective equipment, workplace setting, profession, exposure, contacts, and testing. CONCLUSION A significant number of HCW were reported to be infected with COVID-19 during the first 6 months of the COVID-19 pandemic, with a prevalence of hospitalisation of 15.1% and mortality of 1.5%. Further data are needed to track the continued risks in HCW as the pandemic evolves and health systems adapt.

Abstract
Lower respiratory infections are often caused or precipitated by viruses and are a leading cause of global morbidity and mortality. Mutations in these viral genomes can produce highly infectious strains that transmit across species and have the potential to initiate epidemic, or pandemic, human viral respiratory disease. Transmission between humans primarily occurs via the airborne route and is accelerated by our increasingly interconnected and globalised society. To this date, there have been four major human viral respiratory outbreaks in the 21st century. Healthcare workers (HCWs) are at particular risk during respiratory epidemics or pandemics. This is due to crowded working environments where social distancing, or wearing respiratory personal protective equipment for prolonged periods, might prove difficult, or performing medical procedures that increase exposure to virus-laden aerosols, or bodily fluids. This review aims to summarise the evidence and approaches to occupational risk and protection of HCWs during epidemic or pandemic respiratory viral disease.

Abstract
OBJECTIVE To investigate risk factors for HCW infection in viral respiratory pandemics (SARS-CoV-2, MERS, SARS CoV-1, influenza A H1N1, influenza H5N1) and improve understanding of HCW risk management amidst the COVID-19 pandemic. DESIGN Systematic review and meta-analysis. METHODS MEDLINE, EMBASE, CINAHL, and Cochrane CENTRAL databases were searched from conception until July 2020 for studies comparing infected HCWs (cases) and non-infected HCWs (controls) and risk factors for infection. Outcomes included HCW types, infection prevention practices, and medical procedures. Pooled effect estimates with pathogen-specific stratified meta-analysis and inverse variance meta-regression analysis were completed. GRADE framework was used to rate certainty of evidence. PROSPERO (CRD42020176232) 6 April 2020. RESULTS Fifty-four comparative studies were included (n=191,004 HCWs). Compared to non-frontline HCWs, frontline HCWs were at increased infection risk (OR 1.66 95%CI 1.24 to 2.22) and greater for HCWs involved in endotracheal intubations (risk difference [95%CI]: 35.2% [21.4 to 47.9]). Use of gloves, gown, surgical mask, N95 respirator, face protection, and infection training were each strongly protective against infection. Meta-regression showed reduced infection risk in frontline HCWs working in facilities with infection designated wards (OR -1.04, 95%CI -1.53 to -0.33, p=0.004) and performing aerosol-generating medical procedures in designated centres (OR -1.30 95%CI -2.52 to -0.08; p=0.037). CONCLUSIONS During highly infectious respiratory pandemics, widely available protective measures such as use of gloves, gowns, and face masks are strongly protective against infection and should be instituted, preferably in dedicated settings, to protect frontline HCW during waves of respiratory virus pandemics.

Abstract
Health care workers (HCWs) are vulnerable to the risk of infections and could become vectors of onward transmission of coronavirus disease 2019 (COVID-19). Little is known about the factors which could contribute to increased COVID-19 infection among HCWs in Nigeria. We aimed at assessing the causes of COVID-19 infection among HCWs. We used a qualitative study design to conduct in-depth interview among 16 frontline HCWs participating in the COVID-19 response in Kwara State, Nigeria. Colaizzi's phenomenological method was used in the qualitative analysis of data. We found that HCWs were aware of their vulnerability to the COVID-19 infection, and the reasons attributed included poor knowledge of IPC measures for COVID-19, inadequate supply of personal protective equipment (PPE), poor political will and inadequate health facilities (HFs) management support. Improved political will and better involvement of HFs management teams in infection prevention and control (IPC) systems are needed to reduce the risk for COVID-19 infection among HCWs. We recommend scale-up training on IPC measures particularly hand washing and use of PPE as well as the development of effective points of care risk assessment with a high index of suspicion in HFs.

Abstract
Objective: Although quarantine is an effective measure for the prevention of the spread of infectious diseases, it may have negative effects on the mental health of the isolated individual. During the 2015 outbreak of the Middle East Respiratory Syndrome (MERS) in Korea, healthcare workers came in contact with patients with MERS were quarantined either at home or in a hospital ward. In this study, we aimed to compare the psychiatric symptoms of these employees according to the method of quarantine. Methods: All 146 quarantined staff completed self-report questionnaires. Depressive symptoms were measured using the Patient Health Questionnaire-9, anxiety symptoms were assessed using Spielberger's State-Trait Anxiety Inventory, and acute stress disorder (ASD) symptoms were evaluated using the Stanford Acute Stress Reaction Questionnaire. Results: The in-hospital quarantine group had a higher rate of symptoms of depression (p < 0.001) and ASD (p = 0.014) than the group quarantined at home. Logistic regression analysis showed that respondents quarantined in the hospital (OR = 6.342; 95% CI 1.853-21.708) and those quarantined for longer periods (OR = 1.153, 95% CI = 1.036-1.285) had a higher risk of depressive symptoms. Conclusions: In-hospital quarantine and quarantine for longer periods increase the risk of depressive symptoms. When quarantine measures are taken, certain measures are needed to minimize the risk of psychiatric problems. Appropriate interventions should be implemented if psychiatric problems occur.

MERS-CoV first case was reported on 23rd November 2012 in Saudi Arabia, Since, then MERS has remained on World Health Organization (WHO) Blueprint list and declared pandemic. This study was conducted on MERS lab confirmed cases reported to Ministry of Health, Saudi Arabia and WHO for year 2012-2019. The epidemiology was investigated based on infection rate, death rate, case fatality rate, Gender, Age group, and Medical conditions (Comorbid and Symptomatic). The overall median age of infected male was 58 years and of female was 45 years. While average mortality age in male was 60 years and of female was 65 years which is greater than the global average of 50 years. The results also report that specially after age of 40 years in both men and women, chances of infection are more while comorbidities increase the infection rate. The men are more susceptible to infection than women. In case of asymptomatic distribution trend was vice versa with 69.4% women and 30.6% in men. Second, most infected age group was reduced by 20 years in case of men with 47.37% infection for age group of 20-39 years. This was also observed in age-group of 20-39 years for no comorbid cases (men (50%) & women (79%)). This explains MERS-CoV prevalence in Saudi Arabia, as young and healthy population were infected, and acted as carrier and on coming in contact with vulnerable population (Elderly, chronic and comorbid) transferred the infection. Hence, MERS-CoV outbreak kept on happening from time to time over past years. This finding might very well explain the exponential spread of Novel CoV-19 globally, as initial control measures required older people to stay indoors while younger generation brought infection from outside. Further studies are required for epidemiology analysis based on clusters, travel history and specific disease related mortality.

Abstract
Despite high exposure to Middle East respiratory syndrome coronavirus (MERS-CoV), the predictors for seropositivity in the context of husbandry practices for camels in Eastern Africa are not well understood. We conducted a cross-sectional survey to describe the camel herd profile and determine the factors associated with MERS-CoV seropositivity in Northern Kenya. We enrolled 29 camel-owning households and administered questionnaires to collect herd and household data. Serum samples collected from 493 randomly selected camels were tested for anti-MERS-CoV antibodies using a microneutralisation assay, and regression analysis used to correlate herd and household characteristics with camel seropositivity. Households reared camels (median = 23 camels and IQR 16–56), and at least one other livestock species in two distinct herds; a home herd kept near homesteads, and a range/fora herd that resided far from the homestead. The overall MERS-CoV IgG seropositivity was 76.3%, with no statistically significant difference between home and fora herds. Significant predictors for seropositivity (P ⩽ 0.05) included camels 6–10 years old (aOR 2.3, 95% CI 1.0–5.2), herds with ⩾25 camels (aOR 2.0, 95% CI 1.2–3.4) and camels from Gabra community (aOR 2.3, 95% CI 1.2–4.2). These results suggest high levels of virus transmission among camels, with potential for human infection.

Abstract
Introduction: The world is now facing the COVID-19 pandemic. Experience with SARS-CoV and MERS-CoV, and early reports about SARS-CoV-2 infection suggest that health-care settings and health-care workers (HCWs) are vulnerable in the context of the emergence of a new coronavirus. Areas covered: To highlight the need for prophylactic strategies particularly for HCWs, we identified SARS-CoV, MERS-CoV, and SARS-CoV-2 outbreaks in health-care settings and the incidence of infections in HCWs by a search on MEDLINE and MEDxRIV (for SARS-Cov-2). To identify prophylactic strategies against, we conducted a search on MEDLINE and clinicaltrials.gov about studies involving SARS-CoV, MERS-CoV, and SARS-CoV-2. Expert opinion: HCWs account for a great part of SARS, MERS, and SARS-CoV-2 infections, they may also contribute to the spread of the disease, particularly in health-care settings, and contribute to nosocomial outbreaks. Some preventive strategies were evaluated in previous emerging coronavirus epidemics, particularly in MERS-CoV. For COVID-19 prevention, different chemoprophylaxis with drug repositioning and new agents are under evaluation, and different vaccine candidates entered clinical development, with clinical trials. HCWs are a crucial target population for pre-exposure and post-exposure prophylaxis.

Abstract
Before the current pandemic, there had been two global epidemics from major coronavirus outbreaks since the turn of the century: severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). Both epidemics left survivors with fatigue, persistent shortness of breath, reduced quality of life and a significant burden of mental health problems.It is likely that some of the chronic problems encountered by survivors of SARS and MERS may be relevant for medical planning of the services required for survivors of coronavirus disease 2019 (COVID-19) caused by the novel coronavirus SARS-CoV-2. Given the similarities between the diseases, the recovery and rehabilitation of the survivors of COVID-19 is likely to be focused around cardiopulmonary sequelae, fatigue and the psychological burden of COVID-19, but in a much larger population.

Abstract
During the coronavirus disease 2019 (COVID-19) pandemic, personal protective equipment (PPE) has become a contentious issue in healthcare settings, no more so than in the prehospital environment. The current severe acute respiratory syndrome 2 virus (SARS-CoV-2) has pathogenic and transmission similarities to previous coronaviruses, severe acute respiratory syndrome (SARS-CoV) and Middle Eastern respiratory syndrome (MERS-CoV). There are differences in global and domestic PPE guidelines concerning SARS-CoV-2.

Abstract
To study the acute psychological effects of Coronavirus Disease 2019 (COVID-19) outbreak among healthcare workers (HCWs) in China, a cross-sectional survey was conducted among HCWs during the early period of COVID-19 outbreak. The acute psychological effects including symptoms of depression, anxiety, and post-traumatic stress disorder (PTSD) were assessed using the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder (GAD-7) questionnaire, and the Impact of Event Scale-Revised (IES-R). The prevalence of depression, anxiety, and PTSD was estimated at 15.0%, 27.1%, and 9.8%, respectively. Having an intermediate technical title, working at the frontline, receiving insufficient training for protection, and lacking confidence in protection measures were significantly associated with increased risk for depression and anxiety. Being a nurse, having an intermediate technical title, working at the frontline, and lacking confidence in protection measures were risk factors for PTSD. Meanwhile, not worrying about infection was a protective factor for developing depression, anxiety, and PTSD. Psychological interventions should be implemented among HCWs during the COVID-19 outbreak to reduce acute psychological effects and prevent long-term psychological comorbidities. Meanwhile, HCWs should be well trained and well protected before their frontline exposure.

Abstract
Coronavirus disease (COVID-19) has emerged as a pandemic. The updated knowledge and a positive attitude of health care professionals (HCPs) towards fighting any pandemic is the key to success. Thus, the present study aims to assess the knowledge and attitude of HCPs towards COVID-19 in the Kingdom of Saudi Arabia (KSA). A cross-sectional study was conducted across the KSA, covering its five geographical regions with a non-probability quota sample. Twenty-nine, close-ended questions evaluating the knowledge and attitude domain were included in the questionnaire. It was developed with the help of Qualtrics software and circulated among the HCPs through the electronic mode. We analyzed data from about 1040 HCPs using the statistical package of social sciences (SPSS) v.21. All variables were presented in number and percentages. Univariate and multivariate logistic regression was performed to explore the odds ratio (OR) and adjusted odds ratio (aOR) of independent variables for inadequate knowledge and attitude. Considering the "good" level of the respective domain, the HCPs have displayed better knowledge (48.2%) over attitude (33.8%). Female (aOR: 1.55; 95% CI: 1.15-2.09; p = 0.004), Diploma degree (aOR: 2.51; 95% CI: 1.64-3.83; p < 0.001), 7-10 years' experience (aOR: 1.47; 95% CI: 1.01-2.15; p = 0.045) were at higher risk of having inadequate knowledge compared to their contemporaries. Among the sources, the Ministry of Health (MOH) website was the most popular source of information (76%). The knowledge and attitude of HCPs regarding COVID-19 was similar across all the regions of KSA. However, the continuing education program is warranted to fill the potential gap in knowledge for HCPs in higher-risk groups.

Abstract
Objectives Our aim is to compare the course of the disease between healthcare workers (HCWs) and non-HCWs suffering from covid-19 and eligible for outpatient management. Methods Single-center prospective cohort of outpatients with covid-19, diagnosed between the 10th March and the 2nd April, 2020 with a daily collection of symptoms by an on-line auto-questionnaire. Results A total of 186 patients were included (median age, 41 years [interquartile range, 19–78 years]; 74.2% female), of whom 132 (71%) were HCWs. The median follow-up after symptom onset was 14 (min 4–max 24) days. HCWs were significantly younger than non-HCWs (median age 40.3 years vs. 47.2 years [P < 0.005]), and 81.8% were women. Four patients (2.2%) were hospitalized including one HCW. The median time to recovery was 9 days after symptom onset (95% CI 8-11) in the global population and respectively 8 (95% CI 8–9) and 13 (95% CI 11–15) days in HCWs and in non-HCWs (P < 0.005). After adjusting for age, co-morbidities, and gender, the instantaneous risk ratio for symptom absence in HCWs was 1.76 compared with non-HCWs (95% CI [1.16–2.67], P = 0.037). Conclusion HCWs suffering from covid-19 had favorable outcomes and had a shorter time to recovery than non HCWs.

Abstract
Respiratory infections are very common and highly contagious. Respiratory infectious diseases affect not only the person infected but also the family members and the society. As medical sciences advance, several diseases have been conquered; however, the impact of novel infectious diseases on the society is enormous. As the clinical presentation of respiratory infections is similar regardless of the pathogen, the causative agent is not distinguishable by symptoms alone. Moreover, it is difficult to develop a cure because of the various viral mutations. Various respiratory infectious diseases ranging from influenza, which threaten the health of mankind globally, to the coronavirus disease 2019, which resulted in a pandemic, exist. Contrary to human expectations that development in health care and improvement in hygiene will conquer infectious diseases, humankind's health and social systems are threatened by novel infectious diseases. Owing to the development of transport and trading activity, the rate of spread of new infectious diseases is increasing. As respiratory infections can threaten the members of the global community at any time, investigations on preventing the transmission of these diseases as well as development of effective antivirals and vaccines are of utmost importance and require a worldwide effort.

Abstract
The pandemic infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is widely increasing the patients affiliated with coronavirus disease 2019 (COVID-19) from last December of 2019. It is reported that the entry receptor of SARS-CoV-2 has been confirmed to be angiotensin-converting enzyme 2 (ACE2). Notably, whether the ACE-related inhibitors or drugs modulated ACE2 activity in affecting the viral activity and disease severity of SARS-CoV-2 is still an open question. Dipeptidyl peptidase-4 (DDP-4), a well-known anti-diabetic drug, has been widely used to control the glycemic condition in patients with diabetes. In this article, we are focusing on the impact of ACE inhibitors (ACEI) and DPP4 inhibitors used on SARS-CoV-2 activity and discussions about those drugs that may be related to infectious condition of COVID-19 diseases.

Abstract
BACKGROUND Health care workers (HCWs) are at risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. PURPOSE To examine the burden of SARS-CoV-2, SARS-CoV-1, and Middle East respiratory syndrome (MERS)-CoV on HCWs and risk factors for infection, using rapid and living review methods. DATA SOURCES Multiple electronic databases, including the WHO database of publications on coronavirus disease and the medRxiv preprint server (2003 through 27 March 2020, with ongoing surveillance through 24 April 2020), and reference lists. STUDY SELECTION Studies published in any language reporting incidence of or outcomes associated with coronavirus infections in HCWs and studies on the association between risk factors (demographic characteristics, role, exposures, environmental and administrative factors, and personal protective equipment [PPE] use) and HCW infections. New evidence will be incorporated on an ongoing basis by using living review methods. DATA EXTRACTION One reviewer abstracted data and assessed methodological limitations; verification was done by a second reviewer. DATA SYNTHESIS 64 studies met inclusion criteria; 43 studies addressed burden of HCW infections (15 on SARS-CoV-2), and 34 studies addressed risk factors (3 on SARS-CoV-2). Health care workers accounted for a significant proportion of coronavirus infections and may experience particularly high infection incidence after unprotected exposures. Illness severity was lower than in non-HCWs. Depression, anxiety, and psychological distress were common in HCWs during the coronavirus disease 2019 outbreak. The strongest evidence on risk factors was on PPE use and decreased infection risk. The association was most consistent for masks but was also observed for gloves, gowns, eye protection, and handwashing; evidence suggested a dose-response relationship. No study evaluated PPE reuse. Certain exposures (such as involvement in intubations, direct patient contact, or contact with bodily secretions) were associated with increased infection risk. Infection control training was associated with decreased risk. LIMITATION There were few studies on risk factors for SARS-CoV-2, the studies had methodological limitations, and streamlined rapid review methods were used. CONCLUSION Health care workers experience significant burdens from coronavirus infections, including SARS-CoV-2. Use of PPE and infection control training are associated with decreased infection risk, and certain exposures are associated with increased risk. PRIMARY FUNDING SOURCE World Health Organization.

Abstract
Background Middle East Respiratory Syndrome coronavirus (MERS-CoV) continues to cause intermittent community and nosocomial outbreaks. Obtaining data on specific source(s) and transmission dynamics of MERS-CoV during nosocomial outbreaks has been challenging. We performed a clinical, epidemiological and phylogenetic investigation of an outbreak of MERS-CoV at a University Hospital in Riyadh, Kingdom of Saudi Arabia. Methods Clinical, epidemiological and infection control data were obtained from patients and Healthcare workers (HCWs). Full genome sequencing was conducted on nucleic acid extracted directly from MERS-CoV PCR-confirmed clinical samples and phylogenetic analysis performed. Phylogenetic analysis combined with published MERS-CoV genomes was performed. HCWs compliance with infection control practices was also assessed. Results Of 235 persons investigated, there were 23 laboratory confirmed MERS cases, 10 were inpatients and 13 HCWs. Eight of 10 MERS inpatients died (80% mortality). There were no deaths among HCWs. The primary index case assumed from epidemiological investigation was not substantiated phylogenetically. 17/18 MERS cases were linked both phylogenetically and epidemiologically. One asymptomatic HCW yielded a MERS-CoV genome not directly linked to any other case in the investigation. Five HCWs with mild symptoms yielded >75% full MERS-CoV genome sequences. HCW compliance with use of gowns was 62.1%, gloves 69.7%, and masks 57.6%. Conclusions Several factors and sources, including a HCW MERS-CoV ‘carrier phenomenon’, occur during nosocomial MERS-CoV outbreaks. Phylogenetic analyses of MERS-CoV linked to clinical and epidemiological information is essential for outbreak investigation. The specific role of apparently healthy HCWs in causing nosocomial outbreaks requires further definition.

Abstract
In the recent two decades, three global viral infectious diseases, severe acute respiratory syndrome (SARS), middle east respiratory syndrome (MERS), and coronavirus disease (COVID-19), have occurred worldwide. SARS occurred in November 2002, causing 8096 infected cases, as well as 774 deaths. MERS occurred in June, 2012, causing 2519 confirmed cases, along with 866 associated deaths. COVID-19 occurred in December 2019, as of 30 April 2020, a total of 3,024,059 clinical cases have been reported, including 208,112 deaths. Healthcare workers (HCWs) need to be in close contact with these virus-infected patients and their contaminated environments at work, thus leading to be infected in some of them, even a few of them are died in line of duty. In this review, we summarized the infection status of HCWs during the outbreak of SARS, MERS and COVID-19, with in-depth discussion, hoping to provoke sufficient attention to the HCWs infection status by more people.

Abstract
The Middle East respiratory syndrome coronavirus (MERS-CoV) is a lethal zoonotic pathogen that was first identified in humans in Saudi Arabia and Jordan in 2012. Intermittent sporadic cases, community clusters, and nosocomial outbreaks of MERS-CoV continue to occur. Between April 2012 and December 2019, 2499 laboratory-confirmed cases of MERS-CoV infection, including 858 deaths (34·3% mortality) were reported from 27 countries to WHO, the majority of which were reported by Saudi Arabia (2106 cases, 780 deaths). Large outbreaks of human-to-human transmission have occurred, the largest in Riyadh and Jeddah in 2014 and in South Korea in 2015. MERS-CoV remains a high-threat pathogen identified by WHO as a priority pathogen because it causes severe disease that has a high mortality rate, epidemic potential, and no medical countermeasures. This Seminar provides an update on the current knowledge and perspectives on MERS epidemiology, virology, mode of transmission, pathogenesis, diagnosis, clinical features, management, infection control, development of new therapeutics and vaccines, and highlights unanswered questions and priorities for research, improved management, and prevention.
