摘要
目的探讨新冠肺炎疫情的社区防控管理对流行性感冒防控的影响。方法根据2017-2020年度的流感常规监测数据和2020年1-5月新冠肺炎疫情防控管理前后的流感样病例咽拭子标本,监测流感病毒核酸阳性水平;新冠肺炎疫情期间采集部分新冠肺炎疑似病例咽拭子标本进行流感病毒核酸检测,同时对2020年第4周至第18周流感样病例的咽拭子标本进行新冠病毒核酸检测。结果2017-2020年度,芜湖市流感网络实验室分别检测1310份、1405份和1599份流感样病例咽拭子标本,流感病毒核酸阳性率分别为25.42%、18.65%和36.52%,2020年第4周阳性率82.76%,第10周阳性率为0。新冠肺炎疫情防控前流感病毒核酸阳性率48.84%,新冠肺炎疫情防控期间,流感病毒核酸阳性率仅为6.80%,两者比较差异有统计学意义(χ^(2)=204.952,P<0.05),新冠肺炎疫情期间采集的流感样病例咽拭子标本没有检出新冠病毒核酸阳性,但新冠肺炎疑似病例的咽拭子标本,流感病毒核酸阳性率14.59%。结论实施新冠肺炎社区防控措施,流感病毒核酸阳性率明显下降,防控管理措施对流感的流行具有重要影响,同时发现部分新冠肺炎疑似病例流感病毒核酸阳性。
Objective To explore the impact of community prevention and control of COVID-19 on influenza prevention and control.Method According to the 2017-2020 routine influenza surveillance data and the throat swab samples of influenza-like cases before and after the prevention and control of COVID-19 from January to May 2020,the positive level of influenza virus nucleic acid was monitored.Part of the throat swab specimen from a suspected case of COVID-19 was collected during the outbreak of COVID-19.The throat swab samples of the 4 w to 18 th influenza-like cases in 2020 will be tested for SARS-CoV-2 nucleic acid.Results During 2017 to 2020,the Wuhu City Influenza Network Laboratory tested 1,310,1,405,and 1,599 throat swab samples from influenza-like cases,and the positive rates of influenza virus nucleic acid were 25.42%,18.65%,and 36.52%,respectively.The positive rate in the 4 th week of 2020 was 82.76%,and the positive rate in the 10 th week was 0.Before the prevention and control of COVID-19,the positive rate of influenza virus nucleic acid was 48.84%.During the prevention and control of COVID-19,the positive rate of influenza virus nucleic acid was only 6.80%.The difference between the two period was statistically significant(χ^(2)=204.952,P<0.05),The throat swab specimens of influenza-like cases collected during COVID-19 did not detect positive for SARS-CoV-2 nucleic acid,but the throat swab specimens of suspected cases of COVID-19 showed a positive rate of influenza virus nucleic acid of 14.59%.Conclusion The implementation of community prevention and control measures for COVID-19 has significantly reduced the positive rate of influenza virus nucleic acid.Prevention and control management measures have an important impact on the epidemic of influenza.At the same time,some suspected cases of COVID-19 were found to be positive for influenza virus nucleic acid.
