2012年四川省入境人群疟疾、登革热、乙脑、基孔肯雅热疫情监测分析

Surveillance and analysis of malaria,Dengue fever,Japanese encephalitis B,Chikungunya fever among returned travelers in Sichuan province 2012

目的了解四川省入境人群疟疾、登革热、乙脑、基孔肯雅热的疫情动态,为入境人群疟疾、登革热、乙脑、基孔肯雅热流行趋势的预测、预警和制定防治对策、措施提供科学依据。方法采集入境人员血液,用镜检、胶体金、ELISA、RT-PCR等方法进行疟疾、登革热、乙脑、基孔肯雅热的检测。结果 2012年四川省入境人群疟疾监测阳性率达2.62%,均为赴非洲的劳务人群。登革热、乙脑、基孔肯雅热阳性率均为0。结论 2012年四川省入境人群蚊媒病感染以疟疾尤其是恶性疟为主,感染者主要是赴非洲务工的劳务人员,因此应进一步加大对赴非洲劳务人员关于防疟知识的宣教和防疟措施的推广;出入境检验检疫局应对来自蚊媒病高发地区的国际航班进行重点监控,加大入境人群的传染病监管力度,及早发现输入性蚊媒传染病;本次虽未检出登革热、乙脑和基孔肯雅热,但这些传染病仍有潜在存在的可能性,应高度重视。

Conclusion The main mosquito -borne disease among returnees in Siehuan Province is malaria, especially falciparum malaria. Most of the infected people are laborers back from Africa. Education on the anti - malaria knowledge and anti -malaria measures for them should be enhanced.
