Respiratory syncytial virus (RSV) and influenza are prevalent seasonal community viruses. Although not completely understood, SARS-CoV-2 may have the same means of transmission. Preventive social measures aimed at preventing SARS-CoV-2 spread could impact transmission of other respiratory viruses as well. The aim of this study is to report the detection of RSV and influenza during the period of social distancing due to COVID-19 pandemic in a heavily affected community.
Prospective study with pediatric and adult populations seeking care for COVID-19-like symptoms during the fall and winter of 2020 at two hospitals in Southern Brazil. RT-PCR tests for SARS-CoV-2, influenza A (Flu A), influenza B (Flu B) and respiratory syncytial virus (RSV) was performed for all participants.
1435 suspected COVID-19 participants (1137 adults, and 298 children). were included between May and August. Median age was 37.7 years (IQR = 29.6-47.7), and 4.92 years (IQR = 1.96-9.53), for the adult and child cohorts, respectively. SARS-CoV-2 was positive in 469 (32.7%) while influenza and RSV were not detected at all.
Measures to reduce SARS-CoV-2 transmission likely exerted a huge impact in the spread of alternate respiratory pathogens. These findings contribute to the knowledge about the dynamics of virus spread. Further, it may be considered for guiding therapeutic choices for these other viruses.
呼吸道合胞病毒（RSV）和流感是常见的季节性社区病毒。尽管尚未完全了解，但 SARS-CoV-2 可能具有相同的传播方式。旨在预防 SARS-CoV-2 传播的预防社交措施也可能影响其他呼吸道病毒的传播。本研究旨在报告在 COVID-19 大流行期间因社交距离而导致的一个受严重影响社区中 RSV 和流感的检测情况。
这是一项前瞻性研究，纳入了 2020 年秋季和冬季在巴西南部的两家医院因 COVID-19 样症状就诊的儿科和成人人群。对所有参与者均进行了 SARS-CoV-2、甲型流感（Flu A）、乙型流感（Flu B）和呼吸道合胞病毒（RSV）的 RT-PCR 检测。
共纳入了 1435 例疑似 COVID-19 患者（成人 1137 例，儿童 298 例），纳入时间为 5 月至 8 月。成人组和儿童组的中位年龄分别为 37.7 岁（IQR=29.6-47.7）和 4.92 岁（IQR=1.96-9.53）。SARS-CoV-2 阳性者有 469 例（32.7%），而流感和 RSV 均未检出。
减少 SARS-CoV-2 传播的措施可能对替代呼吸道病原体的传播产生了巨大影响。这些发现有助于了解病毒传播的动态。此外，这些发现可能有助于指导针对这些其他病毒的治疗选择。
