摘　　要：目的分析阳泉市2011~2020年度流感样病例核酸检测数据,了解阳泉市流感流行情况,为今后流感防控提供科学依据。方法对阳泉市哨点医院流感样监测病例以及各县区疾控流感暴发疫情采集病例标本进行核酸检测,并对检测结果统计分析。结果 2011年4月至2020年3月期间,共收到哨点医院流感样病例标本11 047份,核酸检测阳性标本2 179份,阳性率为19.72%,各年度流感病毒阳性率差异有统计学意义(P<0.01)。流感主要流行季节为冬春季,4月份易出现流行高峰,多在中小学生和>61岁老人中间传播。不同性别间流行差异无统计学意义(P>0.05)。9年间共暴发疫情17起,采样187份,阳性147份,阳性率为78.61%,暴发人群均为学生。哨点统计学意义医院和疫情阳性样本中共发现7例混合型流感样病例。结论阳泉市流感重点防控月为12月至次年4月,重点防控措施为加强中小学生和老年人群流感知识宣传教育并提高流感疫苗的接种率。Objective To analyze the nucleic acid test data of influenza-like illnesses and understand the epidemic situation of influenza in Yangquan city during 2011-2020,so as to provide scientific evidence for the prevention and control of influenza in the future. Methods The samples of influenza-like cases collected from sentinel hospitals and epidemic outbreaks in Yangquan city were detected by nucleic acid tests.The testing results were researched for statistical analysis. Results From April 2011 to March 2020,a total of 11 047 samples of influenza-like cases were received, including 2 179 influenza nucleic acid positive samples, with a positive rate of 19.72%.There was a significant statistical difference in the positive rates among years(P<0.01).The epidemic seasons of influenza were winter and spring, and the peaks of influenza usually appeared in April.Influenza viruses were mainly spread among the students in primary and middle schools and the elderly aged >61 years old.There was no statistically significant difference in the positive rate between genders(P>0.05).Throughout the 9 years, there were 17 outbreaks including 187 samples collected and 147 positive samples confirmed with the positive rate of 78.61%.All of the outbreaks occurred in schools.7 mixed infective cases were found in sentinel hospitals and epidemic outbreaks. Conclusion The focus of influenza prevention and control period in Yangquan city is from December to April of the following year.The critical prevention and control measures are to strengthen the publicity and education of influenza knowledge among primary and middle school students and the elderly population and to improve the vaccination rate of influenza vaccine。
