摘要
目的 分析新冠疫情解封后苏州地区甲乙型流感病毒(INFA、INFB)的流行病学特征,为制定防控策略提供科学依据.方法 选取2021年12月20日—2022年11月20日及2022年12月20日—2023年11月20日于苏州大学附属第一医院就诊的1 546 例病人作为研究对象,检测咽拭子INFA与INFB的核酸.结果 2021年12月20日—2022年11月20日苏州地区属于新冠一级防控期间,疫情期间,INFA的阳性率为1.22%,男性0.74%,女性1.83%,INFB的阳性率为1.63%,男性2.21%,女性0.92%;疫情解封后,INFA的阳性率为5.07%,男性4.75%,女性5.59%,INFB的阳性率为0.08%,男性0.13%,女性0%,解封后INFA阳性率高于疫情期间的水平(P＜0.05),且男性升高显著(P＜0.05),女性差异无统计学意义(P=0.11),INFB阳性率低于疫情期间的水平(P＜0.05),且男女性均降低(P均＜0.05).结论 针对新型冠状病毒肺炎的防控措施可有效地阻断INFA的传播,新冠疫情解封后,个人应该继续采取有效的防疫措施.
Abstract
Objective To analyze the epidemiological characteristics of influenza A and B viruses in Suzhou during and after the COVID-19 pandemic,and to provide scientific basis for formulating prevention and control strategies.Methods 1 546 patients who visited the First Affiliated Hospital of Soochow University from December 20,2021 to November 20,2022,and from December 20,2022 to November 20,2023 were selected as the study subjects,and the nucleic acid of influenza A and B virus in pharyngeal swabs was tested.Results From December 20,2021 to November 20,2022,Suzhou belonged to the first level prevention and control period of COVID-19.During the epidemic period,the positive rate of influenza A virus was 1.22%,men were 0.74%,women were 1.83%.The positive rate of influenza B virus was 1.63%,men were 2.21%and women were 0.92%.After the lifting of the epidemic lockdown,the positivity rate of influenza A virus was 5.07%,with 4.75%for males and 5.59%for females.The positivity rate of influenza B virus was 0.08%,with 0.13%for males and 0%for females.After the COVID-19 pandemic,the positivity rate of influenza A virus was higher than the level during the epidemic period(P＜0.05),with a significant increase in males(P＜0.05),with no statistically significant increase in females(P=0.11),the positivity rate of influenza B virus was lower than the level during the epidemic period(P＜0.05),and both genders decreased(both P＜0.05).Conclusion The prevention and control measures against novel coronavirus pneumonia can effectively block the spread of influenza A virus.After the COVID-19 pandemic,individuals should continue to take effective epidemic prevention measures.
