The aim of this study was to analyse changes in influenza detection rates of the influenza seasons 2017/2018, 2018/2019, 2019/2020, and 2020/2021 and the changes in personal awareness of protection during the COVID-19 pandemic.
This retrospective study included patients tested for influenza virus A and B from November 2017 to March 2021 at the Affiliated People's Hospital of Ningbo University (Ningbo, China). Influenza virus A and B tested by direct RT-PCR. A small group of 100 regular participants in influenza virus detection were surveyed on the use of protective measures in four different influenza seasons.
There were 14,902, 14,762, 25,070, and 1107 tests of influenza virus A and B in the four influenza periods, for total positive rates of 32.45%, 35.77%, 29.40%, and 0.54%, respectively. In the two periods of four influenza seasons, from November to January, the total number of influenza samples was 8530, 4980, 22,925, 868; from February to March, the number of tests was 6372, 9782, 2145, 239. Total number of tests and positive rate decreased significantly from February/March onwards of the 2019/2020 season, coinciding with the beginning of COVID-19. The proportion of people taking protective measures also increased during the 2019/20 and 2020/21 flu seasons.
The influenza virus has a high incidence in this area. The diagnosis rate of influenza decreased after the start of the COVID-19 pandemic. The COVID-19 pandemic had an important impact on the detection rates for influenza virus.
本研究旨在分析2017/2018、2018/2019、2019/2020和2020/2021流感季节流感检测率的变化以及新冠疫情期间个人防护意识的变化。
这项回顾性研究纳入了2017年11月至2021年3月在宁波大学附属人民医院（中国宁波）接受甲型和乙型流感病毒检测的患者。甲型和乙型流感病毒通过直接逆转录聚合酶链反应检测。对一小群100名定期参与流感病毒检测的人员进行了调查，了解他们在四个不同流感季节采取防护措施的情况。
在四个流感时期，甲型和乙型流感病毒检测分别有14902、14762、25070和1107次，总阳性率分别为32.45%、35.77%、29.40%和0.54%。在四个流感季节的两个时期，即11月至1月，流感样本总数分别为8530、4980、22925、868；2月至3月，检测次数分别为6372、9782、2145、239。从2019/2020季节的2月/3月起，检测总数和阳性率显著下降，这与新冠疫情开始时间一致。在2019/20和2020/21流感季节，采取防护措施的人员比例也有所增加。
该地区流感病毒发病率较高。新冠疫情开始后流感诊断率下降。新冠疫情对流感病毒检测率有重要影响。
