山东省班氏丝虫病阻断传播后慢性丝虫病患病情况调查

Investigation of status of chronic filariasis patients after transmission interruption transmission of Bancroft's filariasis in Shandong Province

目的了解班氏丝虫病阻断传播后慢性丝虫病患病情况,为后期开展慢性丝虫病防治工作提供科学依据。方法根据全省班氏丝虫病高、中、低流行状况,采用分层整群抽样的方法,在丝虫病流行区,选择有代表性的流行县(市、区),对1周岁以上居民进行调查,对查出的慢性丝虫病患者进行系统查体确诊,对调查资料进行统计、整理、分析。结果防治前(1957年)在济宁等6个流行县(市)内调查38 596例,查出慢性丝虫病患者4 424例,平均患病率为11.46%,班氏丝虫病阻断传播初期,在上述6个县(市、区)调查756 895人,查出慢性丝虫病患者2 346例,患病率为0.31%。结论班氏丝虫病阻断传播后,慢性丝虫病患病率已降至极低水平。

Objective To investigate the infectious status of chronic fdariasis in Shandong Province after transmission interruption of Bancroft＇s filariasis and offer reference for later control activities. Methods Based on different prevalent situation of Bancroft＇s filariasis in Shandong, stratified cluster sampling method was used in the filariasis endemic area and representative prevalent counties （cities, districts） were selected, the residents above age of a year were investigated and positive chronic filariasis patients were checked systematically, then the data were sorted and analyzed. Results Before control in 1957, there 38 596 people were investigated in six endemic counties of Jining and 4 424 chronic filariasis patients were identified, the average prevalent rate was 11.46%, in the early stage of transmission interruption of Bancroft＇s filariasis in the above-mentioned 6 counties （cities, districts）, 756 895 people were investigated and 2 346 chronic filariasis patients were identified, and the average prevalent rate was 0.31%. Conclusion The prevalence of chronic filariasis has dropped to a very low level after the transmission interruption of Bancroft＇s filariasis.
