Detection of Covid-19 in Children in Early January 2020 in Wuhan, China

A Review of the Strategies and Studies on the Prevention and Control of the New Coronavirus in Workplaces

Workplaces are susceptible places for exposure to the new coronavirus (Covid-19) infection due to gathering of many people. Hence, different instructions have been promoted by international organizations regarding high-risk employees and the necessity of implementing health policies to prevent exposure and infection in the workplace. Here we reviewed the required strategies to prevent and control COVID-19 in the workplace. In conclusion, considering the fast spreading and growing prevalence of the new corona virus disease in the world over, all managers, employers, and business owners should receive the necessary information and training on prevention and control strategies based on scientific guidelines and standards.

Surgical Practice in the Shadow of COVID-19 Outbreak

BACKGROUND

COVID-19 epidemic rapidly spread all around the world with over 1500 thousand infected cases and 95000 deaths. This rapid pandemic may overwhelm health care capacity and shortage of resources is a major concern. Literature provided guidelines on management of COVID-19 patients but healthcare service to the normal population should be continued meanwhile. Health system should act immediately and wisely to support essential surgical care while fighting against COVID-19.

METHODS

We conducted a comprehensive search in the major data bases since 2020, using the combination of MeSH words of "COVID-19 " and "surgery" and finally 34 full texts entered to data extraction phase to define a plan for surgical practice during COVID-19 pandemic.

RESULTS

Healthcare workers are at the higher risk of contamination by COVID-19 especially in early stage of outbreak when they were not aware of the different aspects of COVID-19 pandemic. All healthcare staff must be trained to properly use PPE. All patients have to be screened at the hospital triage. All elective surgical interventions must be postponed. Operation room is considered as a place with high risk of cross infection so the highest level of protection should be maintained. Anesthesia, endoscopy and oral surgery are considered as aerosol producing procedures with very high risk of contamination. There is not any evidence to support the risk of infection trough blood products. Postoperative respiratory problems are more common among COVID-19 patients that may increases the estimated risk of morbidity and mortality.

CONCLUSION

COVID-19 pandemic is a dynamic challenge for health system to save the healthcare staff and equipment resources by timely decisions. Healthcare workers are at the higher risk of contamination by COVID-19 especially in early phase of epidemic when the protection is sub-optimal.

Coronavirus: An emergency for healthcare professionals

Coronavirus infection is a transmissible disease. It was first described in China in December, 2019. It has been said to have a person-to-person transmission after prolonged and unprotected exposure. Patients with a potential SARS-CoV-2 exposure present with symptoms of low-grade pyrexia, dry cough, or shortness of breath. People with these symptoms should contact health-care providers before seeking medical intervention so that appropriate preventive actions may be implemented. Health-care facilities should rapidly isolate suspected individuals and notify local health departments for support involved in performing laboratory tests and efforts in containment. The present article describes the nature of virus, method of detection, and its mode of transmission.

Hundreds of severe pediatric COVID-19 infections in Wuhan prior to the lockdown

Before January 22, 2020, only one pediatric case of COVID-19 was reported in mainland China1,2. However, a retrospective surveillance study3 identified six children who had been hospitalized for COVID-19 in one of three central Wuhan hospitals between January 7th and January 15th. Given that Wuhan has over 395 other hospitals, there may have been far more severe pediatric cases than reported.

WHO Declares COVID-19 a Pandemic

The World Health Organization (WHO) on March 11, 2020, has declared the novel coronavirus (COVID-19) outbreak a global pandemic (1). At a news briefing , WHO Director-General, Dr. Tedros Adhanom Ghebreyesus, noted that over the past 2 weeks, the number of cases outside China increased 13-fold and the number of countries with cases increased threefold. Further increases are expected. He said that the WHO is "deeply concerned both by the alarming levels of spread and severity and by the alarming levels of inaction," and he called on countries to take action now to contain the virus. "We should double down," he said. "We should be more aggressive." [...].

An overview of coronaviruses including the SARS-2 coronavirus - Molecular biology, epidemiology and clinical implications

Coronavirus infections have emerged as epidemic and pandemic threats in last two decades. After the H1N1 influenza pandemic in 2009, recently diagnosed novel betacoronavirus or severe acute respiratory syndrome coronavirus (SARS-CoV)-2 has spread across 203 countries and territories in all 5 major continents. World Health Organization (WHO) declared this as a public health emergency of international concern on January 30, 2020. Subsequently on February 11, 2020 a new name was given to this disease i.e. COVID-19 by an expert group from WHO. As of April 12, 2020, 10:00 CET, GMT+2:00, 1,696,588 confirmed cases and 105,952 confirmed deaths have been reported to the WHO. (Coronavirus disease 2019, situation report 83). It possibly originated from a small animal market in Wuhan, China. A cluster of patients were admitted with unusual pneumonia not responding to treatment in various hospitals. Epidemiological, genomic analysis and correlation with other coronaviruses led to the isolation of new coronavirus, closely resembling the bat coronaviruses, from such patients in Wuhan. They were identified as the SARS-CoV-2. This virus infection presents as influenza like illness in the affected people. Fever, cough, respiratory distress with fatigue, diarrhea, nausea and vomiting are common symptoms seen in adults. This may progress on to severe respiratory distress, hypoxia, need for oxygen supplementation and ventilator support as seen in patients in the SARS-CoV-1 epidemic (2003) in Guangdong, China. The transmissibility of SARS-CoV-1 was less as compared to SARS-CoV-2 infection, and it was well controlled with good public health efforts. The present COVID-19 epidemic is still in the acceleration phase of 3 and 4 in various countries. Without any effective antiviral agents available at present, the need of the hour is early case detection, isolation of cases, use of good preventive care measures by the household contacts and in the hospital set up. The results of ongoing clinical trials on hydroxychloroquine, azithromycin alone or in combination and a new antiviral agent remdesivir may help to treat some of the infections. A need for effective vaccine is being seen an as good preventive strategy in this pandemic. However the results of clinical trials and incorporation of vaccines in public health programs is a long way to go.

Are They Just Two Children COVID-19 Cases Confused With Flu?

COVID-19, an emerging infectious disease, has quickly spread all over the world. All human populations are susceptible to this disease. Here we present two pediatric COVID-19 cases, both of whom exhibited negative SARS-CoV-2 nucleic acid tests upon nasopharyngeal swab and were initially diagnosed with influenza A infection. COVID-19 was later confirmed in both patients by serum antibodies of SARS-CoV-2 and nucleic acid test on stool samples. Because children are susceptible to many respiratory pathogens, especially influenza, we concluded that children can be coinfected with multiple pathogens, and more attention should be paid to the exploration of SARS-CoV-2 during the pandemic of COVID-19. This report shows the possibility of misdiagnosis or missed diagnosis of children with COVID-19. We suggest that highly suspected pediatric COVID-19 cases with negative nucleic acid tests on nasopharyngeal swabs should be further checked by performing a nucleic acid test on stool samples and testing serum for antibodies against SARS-CoV-2.

DIAGNOSTIC TESTS AND CLINICAL CHARACTERISTICS OF COVID-19 IN CHILDREN: AN INTEGRATIVE REVIEW

ABSTRACT Objective: to identify in nursing literature scientific production on tests and clinical characteristics of COVID-19 in children and discuss the role of nursing in their care. Methods: an integrative review, which took place between April and June 2020, at Web of Science, CINAHL, BDENF, IBECS, LILACS, MEDLINE (via PubMed) to answer the guiding question: what do research articles on COVID-19 in children reveal? Original research articles published from January to May 2020 were included. Studies without research methodology (case reports, reflection, recommendations), review articles, studies focusing on other themes or conducted exclusively with neonates, infants, adolescents, and adults were excluded. Results: database search found 314 references. After exclusions, 59 studies were selected to be read in full. Of these, 14 articles were selected to compose this review, empirically grouped according to their similarities into two categories: Tests used in COVID-19 in children and Main clinical findings of COVID-19 in children. Conclusion: studies emphasize clinical tests and findings of COVID-19 in children; therefore, the role of nursing at the time of preparation and performance of such tests stands out, since they are an instrument for assessment and follow-up of children with coronavirus as well as in the promotion of adequate and qualified care to minimize the signs and symptoms of this disease, with a view to prompt restoration of their health.

COVID-19 Diagnostic and Management Protocol for Pediatric Patients

This review aims to verify the main epidemiologic, clinical, laboratory-related, and therapeutic aspects of coronavirus disease 2019 (COVID-19) in critically ill pediatric patients. An extensive review of the medical literature on COVID-19 was performed, mainly focusing on the critical care of pediatric patients, considering expert opinions and recent reports related to this new disease. Experts from a large Brazilian public university analyzed all recently published material to produce a report aiming to standardize the care of critically ill children and adolescents. The report emphasizes on the clinical presentations of the disease and ventilatory support in pediatric patients with COVID-19. It establishes a flowchart to guide health practitioners on triaging critical cases. COVID-19 is essentially an unknown clinical condition for the majority of pediatric intensive care professionals. Guidelines developed by experts can help all practitioners standardize their attitudes and improve the treatment of COVID-19.

Spatiotemporal Assessment of COVID-19 Spread over Oman Using GIS Techniques

Coronavirus disease (COVID-19), caused by acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a worldwide challenge effecting millions of people in more than 210 countries, including the Sultanate of Oman (Oman). Spatiotemporal analysis was adopted to explore the spatial patterns of the spread of COVID-19 during the period from 29th April to 30th June 2020. Our assessment was made using five geospatial techniques within a Geographical Information System (GIS) context, including a weighted mean centre (WMC), standard deviational ellipses, Moran's I autocorrelation coefficient, Getis-Ord General-G high/low clustering, and Getis-Ord G i ∗ statistic. The Moran's I-/G- statistics proved that COVID-19 cases in datasets (numbers of cases) were clustered throughout the study period. The Moran's I and Z scores were above the 2.25 threshold (a confidence level above 95%), ranging from 2274 cases on 29th April to 40,070 cases on 30th June 2020. The results of G i ∗ showed varying rates of infections, with a large spatial variability between the different wilayats (district). The epidemic situation in some wilayats, such as Mutrah, As-Seeb, and Bowsher in the Muscat Governorate, was more severe, with Z score higher than 5, and the current transmission still presents an increasing trend. This study indicated that the directional pattern of COVID-19 cases has moved from northeast to northwest and southwest, with the total impacted region increasing over time. Also, the results indicate that the rate of COVID-19 infections is higher in the most populated areas. The findings of this paper provide a solid basis for future study by investigating the most resolute hotspots in more detail and may help decision-makers identify targeted zones for alleviation plans.

Clinical Features and Temporal Changes of RT-PCR and Chest CT in COVID-19 Pediatric Patients

Objective: This work aims to investigate the clinical features and the temporal changes of RT-PCR and CT in COVID-19 pediatric patients. Methods: The clinical, RT-PCR, and CT features of 114 COVID-19 pediatric in-patients were retrospectively reviewed from January 21 to March 14, 2020. All patients had chest CT on admission and were identified as positive by pharyngeal swab nucleic acid test. The clinical features were analyzed, as well as the features and the temporal changes of RT-PCR and CT. Results: Fever (62, 54%) and cough (61, 54%) were the most common symptoms. There were 34 (30%) cases of concurrent infections. The most common imaging features on CT were ground-glass opacities (46, 40%) and consolidation (46, 40%). The bilateral lower lobes were the most common pattern of involvement, with 63 cases (55%) involving one to two lobes, and in 32 (28%) cases CT was normal. Throughout the whole duration of COVID-19 in children, the diagnostic positive rate of RT-PCR has been far higher than that of CT (all P < 0.05). For RT-PCR follow-up, reliable negative results were obtained only 7 days after the onset of symptoms. Though lung involvement on chest CT progressed rapidly in several cases, lung involvement in children with COVID-19 is mild, with a median value of 2 on CT score. Conclusions: RT-PCR is more reliable than CT in the initial diagnosis of pediatric patients with COVID-19. On follow-up, reliable negative RT-PCR results are available 7 days after the initial symptoms. The use of CT should be considered for follow-up purposes only if necessary.

Coronavirus Infection Among Children and Adolescents

Coronavirus infection is a global emergency. Over the past few months, there is a rapid increase in the number of cases and deaths due to coronavirus infection. It has been observed that elderly individuals and those with medical co-morbidities are maximally affected. In children and adolescents, coronavirus infection has low mortality as well as the severity of symptoms are less. Children and adolescents with immunocompromised state, malnutrition, medical co-morbidities and poor hygiene are at higher risk of contracting coronavirus infection. Minimizing this risk factors and adopting appropriate prevention measures will be helpful in limiting the spread of infection as there is no specific treatment and immunization available to date to address this serious issue. This chapter highlights the issues and challenges of coronavirus infection in children and adolescents.

A cross-sectional study of paediatric patients who were admitted to a COVID-19-dedicated PICU from 16 March 2020 to 21 April 2020 with COVID-19.

RESULTS

Six children had confirmed COVID-19 and four had suspected COVID-19. Six had pre-existing chronic medical conditions. Nine had respiratory failure and needed ventilation. Five children, of whom four had chronic medical conditions, died. Four had cardiac arrhythmias. Clinical presentation included fever and cough.

CONCLUSION

COVID-19 can be fatal in paediatric patients, especially in those with a chronic medical condition.

Coronavirus disease 2019 (COVID-19) and pediatric gastroenterology

The coronavirus disease 2019 (COVID-19) is responsible for the new pandemic, which remains an important health and economic challenge worldwide. The causative agent is a novel coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is similar to SARS-CoV-1 and Middle East respiratory syndrome coronavirus (MERS-CoV). Adult infection with respiratory symptoms was considered in the beginning of the pandemic. Now, it has been reported that SARS-CoV-2 infects children and other organs such as the gastrointestinal tract. SARS-CoV-2 enters the host cells through angiotensin converting enzyme-2 (ACE2) receptors as the main receptor expressed in various organs such as the lungs and gastrointestinal tract. Studies on children and the clinical manifestations of COVID-19 do not completely explain the natural course of infection in children, and precisely how the GI tract is involved is not understood. The present article highlights the gastrointestinal manifestations and pathological findings in children with COVID-19. According to the evidence, SARS-CoV-2 infection is milder in children and may present different clinical symptoms from adults. Common clinical manifestations of pediatric COVID-19 include cough, fever, sore throat, malaise, fatigue, and GI symptoms such as diarrhea, abdominal pain, nausea, and vomiting. Furthermore, liver and pancreatic enzymes may be elevated during the pediatric COVID-19 course. Asymptomatic children carriers are potential sources of infection for adults, especially elderly ones. Diagnosis, treatment, and isolation of children are the most effective ways to control the expansion of the COVID-19 pandemic.
