Abstract
Highly pathogenic avian influenza (HPAI) virus subtypes have been increasingly identified in poultry and wild birds since 2021. Between 2020-2023, 26 countries have reported that the H5N1 virus had infected more than 48 mammalian species. On 1 April 2024, a public health alert was issued in Texas when the first confirmed case of human infection with the H5N1 influenza virus was reported in a dairy worker. Cases of H5N1, clade 2.3.4.4b in dairy cows have been reported in several states in the US but were unexpected, even though H5N1 was previously identified in mammalian species, including cats, dogs, bears, foxes, tigers, coyotes, goats, and seals. On 29 April 2024, almost one month after the first reported cases of H5N1 infection in dairy cows, measures were to be implemented by the US Department of Agriculture (USDA) to prevent the progression of H5N1 viral transmission. This editorial summarizes what is currently known about the epidemiology, transmission, and surveillance of the HPAI virus of the H5N1 subtype in birds, mammals, and dairy cows, and why there are concerns regarding transmission to humans.

Abstract
Rhinoviruses (RV) are the major cause of chronic obstructive pulmonary disease and are associated with exacerbation development as well as community-acquired pneumonia in children, leading to substantial morbidity, mortality, and hospital admission. Here we have examined how changes at the amino terminal of the conserved VP4 epitope of different RV serotypes may affect pulmonary cytokine and chemokine responses and disease severity. Samples positive for rhinovirus were used for genetic characterization, followed by profiling gene expression of pulmonary Th1 and Th2 cytokines/chemokines by RT-PCR arrays. Genetic sequencing and homology 3D modeling revealed changes at the amino terminal of the conserved viral protein 4 (VP4) epitope in the RV-A101 serotype, especially serine at several positions that are important for interactive binding with the host immune cells. We found dysregulation of pulmonary gene expression of Th1- and Th2-related cytokines and chemokines in RV-A 101 and RV-C 8 pneumonia patients. These findings might contribute to a better understanding of RV immunity and the potential mechanisms underlying the pathogenesis of severe RV infections, but further functional studies are needed to confirm the causal relationship.

[PMID: 38298093 PMCID: PMC10845785 DOI: 10.12659/msm.943911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Accepted: 01/24/2024] [Indexed: 02/02/2024] Open
Abstract
In December 2023, the US Centers for Disease Control and Prevention (CDC) published the updated 2024 Advisory Committee on Immunization Practices (ACIP) Adult Immunization Schedule, which is available online for access by the public and healthcare professionals. These new guidelines come at a time when the incidence of vaccine-preventable viral infections from SARS-CoV-2 (JN.1), respiratory syncytial virus (RSV), influenza, and measles are increasing in adults and children due to vaccine hesitancy, or non-compliance. This editorial aims to highlight the ongoing global health concerns for the consequences of increasing reports of vaccine-preventable infections, including SARS-CoV-2 (JN.1), influenza, RSV, and measles, to understand the causes of vaccine hesitancy, and introduce some public health measures that could improve vaccine uptake.

Abstract
BACKGROUND COVID-19/SARS CoV-2 continue to pose a threat to human health and placed millions of livelihoods at risk. Surveillance for the other circulating seasonal viruses during this pandemic is necessary to understand the manifestations of the CoV-2 pandemic and their incidence. METHODS A detailed study survey was performed on subjects with acute respiratory infections (ARI) and severe acute respiratory infection (SARI) in the King Institute of Preventive Medicine and Research, Chennai from April 2020 to March 2022. A total of 1480 patients presenting with either SARI (41.8%) or ARI (58.1%) were screened for SARS CoV-2 and other respiratory viruses. The SARS CoV-2 real-time PCR was carried out using ICMR-approved kits and other respiratory viruses were detected using the commercially available real-time kit. RESULTS Out of the 620 SARI patients, 198 (31.9%) were positive for SARS CoV-2 RNA. Out of the 860 ARI patients, 352 (40.9%) were positive for SARS CoV-2 RNA. Among the 550 patients positive for SARS CoV-2, 7 (1.2%) were positive coexistent with other respiratory viruses. Among the 930 patients with negative SARS CoV-2, 222 (23.8%) were positive for other common respiratory viruses (p = 0.001). Influenza viruses (36.9%) predominated followed by RSV (31.9%) and Parainfluenza virus (13.5%). CONCLUSION This study suggests that viral coinfections are significantly higher among SARS CoV-2 negative individuals (23.8 vs. 1.2%). It is possibly due to viral interference and the competitive advantage of SARS CoV-2 in modulating the host immunity. Continuous surveillance is necessary for understanding the viral co-infection mechanisms.

Abstract
OBJECTIVE With the current global pandemic of COVID-19, there is concern that an influenza outbreak could exacerbate the health care burden. Improving the influenza vaccination rate is becoming more critical because controlling the spread of influenza is essential for reducing excess mortality. Therefore, we investigated whether the influenza vaccination rate changed during the COVID-19 pandemic in Japan and identified the factors associated with influenza vaccination uptake. DESIGN This cross-sectional study used data from an Internet survey with adjustments to approximate a nationally representative estimate using inverse probability weighting. SETTING A total of 23 142 respondents, aged 15 to 80 years, were evaluated to estimate weighted percentages and prevalence ratios with 95% confidence intervals of influenza vaccination in the period 2020-2021. RESULTS Overall, in the period 2020-2021, the influenza vaccination rate rose from 38.1% before the COVID-19 pandemic to 44.6%. "Using traditional media" was a positive predictor of influenza vaccination uptake. "Using social media," "COVID-19 vaccine hesitancy," and "living in a prefecture with a high proportion of COVID-19 cases" were negative predictors. CONCLUSIONS It is crucial to use predictors of influenza vaccination, such as how to use the media, for promoting a more widespread influenza vaccination uptake. The results of this study may be helpful in improving influenza vaccination rates, which could reduce the burden on health care services during outbreaks of influenza and COVID-19.

Abstract
OBJECTIVES The purpose of this investigation was to evaluate the effects of the COVID-19 pandemic on the respiratory syncytial virus (RSV) prevention program at our institution across three time frames: 2019-2020, 2020-2021, and 2021-2022. METHODS We carried out a descriptive, single-site observational study spanning four years, from June 2019 to June 2022. Our study included patients in our institution's RSV program who met our enrollment criteria. We collected information about the number of children receiving immunoprophylaxis, immunoprophylaxis doses, and RSV risk factors. RESULTS The number of patients receiving immunoprophylaxis dropped across the three periods, from 315 patients in the first period (2019-2020) to 176 in the second period (2020-2021), and further decreased to 128 in the third period (2021-2022). Following the COVID-19 pandemic, there was a 50% reduction in the number of patients receiving immunoprophylaxis. The proportion of RSV-infected patients remained relatively similar in the first and second periods (2.86% and 2.27%, respectively) but increased in the third period (5.47%). In the first period, most patients (60.32%) received seven doses, 11.75% got four to six doses, and 27.95% received three doses or fewer. The second period saw 59.66% of patients receiving four to six doses and 40.34% receiving three doses or fewer. In the third period, a mere 9.38% received four to five doses, while 90.63% got three doses or fewer. CONCLUSIONS While preventative measures associated with COVID-19 may have helped reduce the number of RSV cases, the pandemic seems to have caused a significant decrease in the number of children receiving immunoprophylaxis and the doses of immunoprophylaxis. More extensive, multicenter research is needed to understand the impact of the COVID-19 pandemic on RSV immunoprophylaxis, its activity, and seasonal patterns fully.

Abstract
Aim: Influenza A virus (IAV) causes serious illness and is responsible for significant morbidity and mortality. To diagnose IAV infection in its early stages, a quick, sensitive, precise detection method is needed for effective clinical management. Materials & methods: In-house hydroxylnaphthol blue (HNB)-based RT-LAMP assay for early detection of IAV using the HA gene was compared with RT-PCR/multiplex-RT-PCR. Results: For the reference strains of IAV, (H1N1 (A/Texas/50/2012) and H3N2 (A/Malaysia/2089302/2009)) RT-LAMP and RT-PCR/M-RT-PCR exhibited a limit of detection (LOD) of 10 and 100 fg/ml, respectively. Conclusion: HNB-based RT-LAMP is a rapid, sensitive, cost-effective diagnostic tool, and could be a point-of-care test for IAV patients during outbreaks.

Abstract
Strains of avian influenza A, believed to have originated in poultry with transmission to wild birds, have been associated with epidemics and four major pandemics in humans in the past century. The 1918 influenza pandemic was caused by an avian strain of the influenza A(H1N1) virus that initially adapted to infect humans and then rapidly spread between humans. Since 2021, highly pathogenic avian influenza (HPAI) virus subtypes have been identified in poultry and wild birds. In October 2022, the HPAI virus variant A(H5N1) was isolated from intensively farmed American mink. The World Health Organization (WHO), the US Centers for Disease Control and Prevention (CDC), and the European Union Reference Laboratory for Avian Influenza (EURL) have stated that the risk of human infection from birds and mammals and human-to-human transmission from known HPAI viruses is currently low. However, they recommend increased infection surveillance and preparedness. This editorial aims to present the status of HPAI virus transmission in poultry, wild birds, and mammals to highlight the importance of international infection surveillance, control, and preparedness to prevent the next human influenza pandemic.

Abstract
Background: Respiratory viral diseases have considerably declined since the COVID-19 outbreak, perhaps through influence by nonpharmaceutical interventions. We conducted a cross-sectional study using the CDC database to compare the pre- vs. post-pandemic flu activity (incidence) between the US states. Our secondary objectives were to estimate the association between flu activity and flu vaccination rates and compare the national trends of flu and RSV activities since the pandemic outbreak. Methods: We estimated the difference between pre-pandemic (April 2019–March 2020) and post-pandemic (April 2020–March 2021) flu activity between individual states using the Wilcoxon signed-rank test. The association between flu activity and immunization rates was also measured. Finally, parallel time trend graphs for flu and RSV activities were illustrated with a time series modeler. Results: The median (IQR) pre-pandemic flu activity was 4.10 (1.38), higher than the post-pandemic activity (1.38 (0.71)) (p-value < 0.001). There was no difference between pre-pandemic (45.50% (39.10%)) and post-pandemic (45.0% (19.84%)) flu vaccine acceptance (p-value > 0.05). Flu activity and vaccination rates were not associated (p-value > 0.05). Flu activity has declined since the COVID-19 outbreak, while RSV made a strong comeback in June 2021. Conclusion: Flu activity has significantly diminished throughout the pandemic while a sudden upsurge in RSV is a public health concern indicative of possible resurgence of other viruses. Flu vaccine acceptance neither changed during the pandemic nor influenced the diminished Flu activity.

Abstract
INTRODUCTION Impacts of COVID-19 mitigation measures on seasonal respiratory viruses is unknown in sub-tropical climates. METHODS We compared weekly testing and test-positivity of respiratory infections in the 2019-2020 respiratory season to the 2012-2018 seasons in southern Puerto Rico using Wilcoxon signed rank tests. RESULTS Compared to the average for the 2012-2018 seasons, test-positivity was significantly lower for Influenza A (p<0.001) & B (p<0.001), respiratory syncytial virus (RSV) (p<0.01), respiratory adenovirus (AdV) (p<0.05), and other respiratory viruses (p<0.001) following March 2020 COVID-19 stay at home orders. CONCLUSIONS Mitigation measures and behavioral social distancing choices may have reduced respiratory viral spread in southern Puerto Rico.

Abstract
Healthcare professionals have an ethical, medico-legal, and professional responsibility to report all suspected adverse events following immunization to relevant national reporting agencies as part of the process of post-marketing drug safety monitoring. In the US, the Vaccine Adverse Event Reporting System (VAERS) is co-sponsored by the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA). Data from VAERS and other national and global reporting systems show very low rates of adverse events related to currently approved SARS-CoV-2 vaccines. Populations studies have supported the findings from adverse event reporting systems. The presentation, monitoring, and reporting of adverse events related to SARS-CoV-2 vaccines may have future applications in vaccine monitoring for several other potential pandemic zoonotic infections. This editorial aims to summarize the current understanding of adverse events from current COVID-19 vaccines from global adverse event reporting systems, rather than individual case reports or anecdotal reporting in the media.
