Analysis on surveillance of imported malaria cases at Hefei port from 2015 to 2016

目的探讨合肥口岸输入性疟疾的流行病学特征,为进一步加强输入性疟疾防控工作提供科学依据。方法对2015—2016年在安徽国际旅行卫生保健中心进行归国体检的入境人员,开展疟疾快速检测(胶体金法)、血涂片镜检和防控知识问卷调查,对资料进行描述性分析。结果 2015—2016年,在合肥口岸287名入境人员中共发现46例疟疾病例,总阳性率16.0%。均为男性,病例年龄分布在30~49岁年龄组,占82.6%。职业以工人为主,国内居住地占首位的是肥东县,占50%;境外停留国家以安哥拉最多,占56.5%,境外停留时间主要是12~23个月,占47.8%。在国外发病1~2次者36例,占78.3%。疟疾防控知识中"疟疾没有疫苗预防"的知晓率最低(45.7%)。结论合肥口岸输入性疟疾防控形势依然严峻,且有反复发病的情况,必须做好出入境人员健康教育和监测工作。
