摘要
目的对2005—2020年广元市的流行性乙型脑炎病例进行统计分析,掌握其流行病学特征,为广元市下一步流行性乙型脑炎防控工作提供参考。方法收集2005—2020年中国疾病预防控制信息系统中报告的所有现住址为广元市的乙脑病例,整理乙脑专报系统中的个案调查信息,运用描述性流行病学方法进行统计分析,并进行率的比较及趋势分析。结果2005—2020年广元市共报告流行性乙型脑炎确诊或临床病例217例,年均报告发病率为0.48/10万,总体呈下降趋势(χ^(2)_(趋势)=102.849,P=0.001)。2005—2008年的年均报告发病率高于2009—2020年的年均报告发病率(χ^(2)=127.12,P=0.001)。报告病例主要在每年7-9月发病,发病人群91.70%为14岁及以下的学生或儿童,各县区均有病例发生,80.18%的病例未接种或无明确的接种史。结论广元市的流行性乙型脑炎发病总体有所下降,各县(区)均有病例报告,有明显的时间和人群分布特征,同时病例中有较大比例的免疫空白。为更好地做好乙脑等蚊传疾病的防控,应进一步做好14岁及以下儿童的乙脑常规疫苗接种;加大三带喙库蚊孳生地的清理;倡导居民健康生活方式,从而减少成人发病。
Objectives To analyze the epidemiological characteristics of Japanese encephalitis from2005 to 2020 in Guangyuan City so as to provide reference for the next step of epidemic B encephalitis prevention and control in Guangyuan City.Methods Information about cases of Japanese encephalitis in Guangyuan City were collected from a report on Chinese Disease Prevention and Control Information system in 2005 to 2020.Descriptive statistics were performed,the rates and trends were compared and alylized.Results Totally,217 confirmed or clinical cases of Japanese encephalitis were reported in Guangyuan from 2005 to 2020,with an average annual reported incidence of 0.48/105,showing an overall downward trend(χ^(2)=102.849,P=0.001).The average annual reported incidence in 2005 to 2008 was higher than that reported in 2009 to 2020(χ^(2)=127.12,P=0.001).The reported cases were mainly occurring from July to September in each year.Specifically,91.70%of the patients were students or children aged 14 years and younger.All counties and districts have reported the cases.Notably,80.18%of the cases were not vaccinated or no clear history of vaccination.Conclusions The overall incidence rate of Japanese encephalitis in Guangyuan has decreased,with features of obvious time,population distribution and a large proportion of immune blank.Japanese encephalitis cases were reported in all counties and districts.In order to better prevent and control Japanese encephalitis and other mosquito diseases,it is necessary to do routine Japanese encephalitis vaccination for children aged 14 and younger,increase the breeding sites of Sanbibeak,and advocate a healthy lifestyle to reduce the incidence of adults.
