To control the pandemic caused by SARS-CoV-2, the implementation of social and hygienic confinement measures was determined in all countries. These measures reduce the circulation of most respiratory viruses that are transmitted preferentially by air and contact.
The impact of these measures on non-Covid respiratory viruses during the period August-December 2020 and 2019 has been comparatively analyzed. To all nasopharyngeal aspirates that were negative against SARS-CoV-2 by RT-PCR and the suspicion of acute respiratory infection persisted, were subjected to a new RT-PCR that simultaneously and differentially amplifies 21 different respiratory viruses.
In the year of the pandemic, a 36.6% decrease was detected in the number of respiratory samples studied and 66% in their positivity in relation to 2019. All viruses showed reduction percentages of between 40-100%. The only viruses that circulated during and after national lockdown were rhinovirus (74.1%), adenovirus (10.1%), and enterovirus (9.6%).
The measures used to control the SARS-CoV-2 infection have also affected the community circulation of most respiratory viruses including influenza and respiratory syncytial virus.
为控制由严重急性呼吸综合征冠状病毒2(SARS-CoV-2)引起的大流行,所有国家都确定实施社会和卫生限制措施。这些措施减少了大多数主要通过空气和接触传播的呼吸道病毒的传播。
对2020年8月至12月期间以及2019年这些措施对非新冠呼吸道病毒的影响进行了比较分析。对所有经逆转录聚合酶链反应(RT-PCR)检测对SARS-CoV-2呈阴性但仍怀疑有急性呼吸道感染的鼻咽抽吸物,进行新的RT-PCR检测,该检测可同时并分别扩增21种不同的呼吸道病毒。
在大流行年份,与2019年相比,所研究的呼吸道样本数量减少了36.6%,阳性率降低了66%。所有病毒的减少百分比在40%-100%之间。在全国封锁期间及之后仍有传播的唯一病毒是鼻病毒(74.1%)、腺病毒(10.1%)和肠道病毒(9.6%)。
用于控制SARS-CoV-2感染的措施也影响了包括流感和呼吸道合胞病毒在内的大多数呼吸道病毒的社区传播。
