Introduction: The epidemiology of respiratory syncytial virus (RSV) infection has changed during the COVID-19 pandemic. Our objectives were to describe the RSV epidemic in 2021 and compare it with the previous years to the pandemic.
Methods: Retrospective study performed in Madrid (Spain) in a large pediatric hospital comparing the epidemiology and clinical data of RSV admissions during 2021 and the two previous seasons.
Results: 899 children were admitted for RSV infection during the study period. During 2021, the outbreak peaked in June and the last cases were identified in July. Previous seasons were detected in autumn-winter. The number of admissions in 2021 was significantly lower than in previous seasons. There were no differences between seasons regarding age, sex or disease severity.
Conclusion: RSV hospitalizations during 2021 in Spain moved to summer with no cases in autumn and winter 2020-2021. Unlike other countries, clinical data were similar between epidemics.

Respiratory syncytial virus (RSV) infections are a significant public health concern for pediatric populations and older adults, with seasonal winter outbreaks in the United States (US). Little is known about the timing of RSV epidemics across age groups and the relative contribution of within-group and between-group transmission of RSV in each age group. The lack of understanding of age-specific RSV transmission patterns limits our ability to inform vaccination policies.

The seasonality and epidemiology of viral acute respiratory infections (ARIs) have changed since the coronavirus disease 2019 pandemic. However, molecular-based ARI surveillance has not been conducted in Japan. We developed a regional surveillance program to define the local epidemiology of ARIs.

Capsid Integrity qPCR (CI-qPCR) assays offer a promising alternative to cell culture-based infectivity assays for assessing pathogenic human virus viability in wastewater. This study compared three CI-qPCR methods: two novel (Crosslinker, TruTiter) and one established (PMAxx dye). These methods were evaluated on heat-inactivated and non-heat-inactivated 'live' viruses spiked into phosphate-buffered saline (PBS) and wastewater, as well as on viruses naturally present in wastewater samples.

Unlabelled: Palivizumab, a humanized monoclonal antibody against the respiratory syncytial virus (RSV), currently is indicated in groups at higher risk of developing severe RSV disease, such as extreme premature infants and patients with hemodynamically significant heart disease. In Chile, this strategy is guaranteed by Law 20850 (Ricarte Soto Law). Nevertheless, barriers to its administration included the need to transfer these labile patients and exposure to other users, with the risk of contagion in waiting rooms.

Background: Respiratory syncytial virus (RSV) infection in the first year of life has been linked with an increased risk for asthma. Some propose that RSV-induced inflammation leads to lasting airway changes, while others contend that RSV bronchiolitis is a marker for underlying predisposition. Social distancing adopted during the COVID-19 pandemic has led to a dramatic reduction in RSV activity, providing an unexpected opportunity to investigate this debate.
