The aim of this study was to determine whether the occurrence of the SARS-CoV-2 pandemic affected the incidence of influenza in Poland and the efficiency of the SENTINEL influenza surveillance system.
The analysis was based on virologic data from the 2018/2019-2021/2022 epidemic seasons. The data in question were obtained from the SENTINEL influenza surveillance system, which is utilized in Poland.
In the 2020/2021 epidemic season, only one positive case was confirmed. In the epidemic season of 2021/2022, the number of positive cases increased. There was a delay in the peak of the season, since the start of pandemic, which was observed in the 14th week of 2022. Previously, it was recorded in the 5-10th week, depending on the season. Before the pandemic, the number of positive samples in relation to the tested ones oscillated between 41-49.4%. After the pandemic, it was 0.3% and below 20%, respectively, for season 2020/2021 and season 2021/2022.
The COVID-19 pandemic caused a decline in many other infectious diseases, including influenza, as a result of the numerous lockdowns and from people shifting to remote work. Other safety measures, such as obligatory protective masks and the use of disinfectants, had a significant impact on reducing the number of cases.
本研究的目的是确定新型冠状病毒肺炎大流行的发生是否影响了波兰流感的发病率以及哨点流感监测系统的效率。
分析基于2018/2019 - 2021/2022流行季节的病毒学数据。相关数据来自波兰使用的哨点流感监测系统。
在2020/2021流行季节,仅确诊1例阳性病例。在2021/2022流行季节,阳性病例数量增加。自疫情开始以来,该季节的高峰出现延迟,在2022年第14周观察到,此前根据季节不同记录在第5 - 10周。在疫情之前,阳性样本数量与检测样本数量的比例在41% - 49.4%之间波动。疫情之后,2020/2021季节和2021/2022季节分别为0.3%及低于20%。
由于多次封锁以及人们转向远程工作,新冠疫情导致包括流感在内的许多其他传染病发病率下降。其他安全措施,如强制佩戴防护口罩和使用消毒剂,对减少病例数量产生了重大影响。
