摘要
目的分析合肥市麻疹发病与流行趋势,为控制和消除麻疹提供依据。方法对2005年合肥市麻疹监测系统确诊的841例麻疹病例进行流行病学分析。结果2005年合肥市麻疹发病率为18.46/10万(841/4 556 978),较2004年上升了720.44%,全年共发生学校暴发5起,其他以高度散发形式存在,呈流行态势。发病高峰集中在3、5两月;发病年龄呈双相移位现象。病例中有免疫史的占29.1%,无免疫史和免疫史不详的占25.6%和45.3%;流动人口发病占总病例数的40%左右。结论流动儿童免疫接种率低,易感人群积累及流动人口比例增多是造成发病上升的主要原因,提高麻疹疫苗接种质量并针对薄弱地区、重点人群进行麻疹疫苗(MV)的强化免疫,是控制麻疹暴发和流行的重要手段。
Objective Incidence and trend of measles in Hefei were analyzed so as to provide basis for controlling and eliminating measles. Methods： 841 confirmed measles cases reported in 2005 from the surveillance system were analyzed. Results ： Incidence of measles was 18.46/100000 （ 84.1/4556978 ） and increased 720.44%, compared with that in 2004. Totally, five outbreaks occurred in schools in 2005. Other cases occurred sporadically. Incidence peak occurred in March and May Double - phase shifting phenomenon was observed in different age groups. Among the cases, 29.1% had the immunity history. 25.6% had not immunity history and 45.3% had unclear immunity history. 40% or so were migrants. Conclusion ： Migrant children had lower vaccination rate. Accumulation of non - immunity population and increasing proportion of migrant population were the main causes leading to higher incidence. Improving the MV vaccination quality and intensifying MV vaccination to key population were the effective way to control outbreak and prevalence of measles.
