不同防治阶段慢性丝虫病病人分布情况分析

目的了解不同防治阶段人群慢性丝虫病患病率，为开展慢性丝虫病控制和护理工作提供科学依据。方法对广东省丝虫病不同防治阶段的丝虫病人症状体征调查资料进行统计与分析。结果防治丝虫病前、基本灭丝考核、防治后期监测、消灭丝虫病后4个阶段的慢性丝虫病患病率分别为2．92％(479／16423)、0．34％(373／109561)、0．08％(172／208683)和0．06％(18／29700)。慢性丝虫病3种主要体征鞘膜积液、乳糜尿、象皮肿的构成比随着丝虫病的防治进展而发生改变，防治前鞘膜积液占的比例最大(75．16％)，以后逐渐减少，到消灭阶段调查已难发现；而乳糜尿和象皮肿所占比例越来越大，到消灭阶段分别占42．11％和51．63％。结论通过防治，慢性丝虫病发病率已得到有效控制，但还存在不少象皮肿和乳糜尿病例，必须寻找有效的控制和治疗方法，尽量减轻其痛苦和提高生活质量。
