持续的2019冠状病毒病（COVID-19）大流行促使世界各地采取公共卫生措施，以减轻疾病传播，包括；旅行限制、封锁、洗手信息、使用口罩和保持身体距离。随着大流行的进展，越来越多的报告季节性呼吸道病毒的异常减少。我们的目的是评估大流行对加拿大实验室确认的季节性非sars - cov -2呼吸道病毒检测的影响。流行病学数据来自加拿大呼吸道病毒检测监测系统。分析了从2014年8月30日结束的一周到2021年3月13日结束的一周的每周数据。我们比较了2020/2021季节与2014年至2019年大流行前季节的实验室检测和检测量趋势。我们观察到，与大流行前的季节相比，2020-2021年期间所有季节性呼吸道病毒检测呈阳性的百分比显着降低。甲型流感和乙型流感的阳性率分别降至大流行前水平的0.0015倍和0.0028倍，RSV的阳性率降至大流行前水平的0.0169倍。持续检测到肠病毒/鼻病毒，但流行模式和强度存在区域差异。我们报告2020/2021年大多数季节性呼吸道病毒的年度季节性流行有效消失。这种急剧下降可能与大流行期间实施多层次公共卫生措施有关。这些措施的影响可能与公共卫生实践有关，以减轻季节性呼吸道病毒流行，并为应对未来呼吸道病毒大流行提供信息。这项研究不需要额外的资金来源。
The ongoing coronavirus disease 2019 (COVID-19) pandemic has resulted in implementation of public health measures worldwide to mitigate disease spread, including; travel restrictions, lockdowns, messaging on handwashing, use of face coverings and physical distancing. As the pandemic progresses, exceptional decreases in seasonal respiratory viruses are increasingly reported. We aimed to evaluate the impact of the pandemic on laboratory confirmed detection of seasonal non-SARS-CoV-2 respiratory viruses in Canada. Epidemiologic data were obtained from the Canadian Respiratory Virus Detection Surveillance System. Weekly data from the week ending 30th August 2014 until the week ending the 13th March 2021 were analysed. We compared trends in laboratory detection and test volumes during the 2020/2021 season with pre-pandemic seasons from 2014 to 2019. We observed a dramatically lower percentage of tests positive for all seasonal respiratory viruses during 2020-2021 compared to pre-pandemic seasons. For influenza A and B the percent positive decreased to 0•0015 and 0•0028 times that of pre-pandemic levels respectively and for RSV, the percent positive dropped to 0•0169 times that of pre-pandemic levels. Ongoing detection of enterovirus/rhinovirus occurred, with regional variation in the epidemic patterns and intensity. We report an effective absence of the annual seasonal epidemic of most seasonal respiratory viruses in 2020/2021. This dramatic decrease is likely related to implementation of multi-layered public health measures during the pandemic. The impact of such measures may have relevance for public health practice in mitigating seasonal respiratory virus epidemics and for informing responses to future respiratory virus pandemics. No additional funding source was required for this study.
