摘要
目的分析2018—2023年中国森林脑炎的流行特征,揭示其发生规律,为制定森林脑炎的防控策略提供科学依据。方法利用中国疾病预防控制信息系统,收集2018—2023年间中国森林脑炎病例数据,采用描述性流行病学方法进行分析。结果2018—2023年,全国森林脑炎报告病例共656例,年平均发病率为0.008/10万,死亡2例,病死率为0.30%。报告病例主要集中在内蒙古自治区、黑龙江省和吉林省,占总报告病例的98.6%,该3省(地区)年平均发病率0.06/10万~0.21/10万,年平均实验室确诊率为53.35%,存在显著的地区间差异(P<0.05)。森林脑炎发病高峰在5-7月,其间报告病例数占总病例数的89.33%。发病人群主要为农民、家务及待业人员和工人,构成比分别为46.95%、27.13%、11.43%。全国报告病例主要集中于40~69岁年龄组,其中50~59岁年龄组占比最高,为37.65%,且男性发病多于女性。结论2018—2023年中国森林脑炎报告病例主要集中于内蒙古自治区东部、黑龙江省和吉林省,春夏季为发病高峰期,50~59岁年龄组、农民及家务待业人员是主要发病群体。
Objective To analyze the epidemiological characteristics of tick-borne encephalitis(TBE)in China from 2018 to 2023,explore the development pattern of TBE,and provide a scientific basis for effective prevention and control of TBE.Methods The case data of TBE in China spanning from 2018 to 2023 was collected through the China Information System for Diseases Control and Prevention(CISDCP),followed by descriptive epidemiological analysis.Results Between 2018 to 2023,a total of 656 TBE cases were reported in China,with an average annual incidence of 0.008 per 100,000 individuals.Among these cases,there were 2 fatalities,yielding a case fatality rate of 0.30%.The distribution of TBE was mainly concentrated in Inner Mongolia Autonomous Region,Heilongjiang Province and Jilin Province,accounted for 98.6%of the total number of reported cases.The average annual incidence rate of TBE in these regions was 0.06-0.21 per 100,000 individuals.The average laboratory confirmation rate of TBE cases was 53.35%,with significant regional differences(P<0.05).The number of TBE cases in the months of May to July,accounted for 89.33%of the total cases,indicated a peak in incidence during these months.TBE predominantly affected farmers,housewives and unemployed individuals,and workers,with ratios of 46.95%,27.13%and 11.43%,respectively.The majority of reported cases of TBE in China were concentrated in the age group of 40-69,with more cases in males than females.The highest proportion was observed in the age group of 50-59(37.65%).Conclusion From 2018 to 2023,reported cases of TBE in China were mainly concentrated in Inner Mongolia Autonomous Region,Heilongjiang and Jilin Province.The peak months for the incidence of TBE were May-July,the occupational composition of the population peaks among farmers,housewives and unemployed individuals,and workers,as well as the 50-59 age group.
