江西省丝虫病流行与防治

PREVALENCE AND CONTROL OF FILARIASIS IN JIANG-XI PROVINCE

江西省有75个县(市)流行丝虫病,其中33个县(市)为马来丝虫病流行区,9个县为班氏丝虫病流行区,33个县(市)为马来和班氏两种丝虫病混合流行区。防治前平均微丝蚴率为8.33%。中华按蚊、致倦库蚊分别为我省马来和班氏丝虫病的主要传播媒介。1972年,全省丝虫病防治实行分类指导和反复查治,微丝蚴血症给予海群生系统治疗。在发病率高的部分村采取全民预防服药和海群生药盐措施。1988年全省考核验收阶段微丝蚴率已降至0.08%,以村为单位微丝蚴率均降至1%以下,1990年10月卫生部组织抽查复核后确认我省已达到基本消灭丝虫病。

Filariasis was previously endemic in 75 counties and cities of Jiangxi province. Among them, 33 were malayan filariasis endemic areas, 9 bancroftian filariasis endemic areas, 33 mixed endemic areas. The average microfilaria rate was 8. 33% before control program. The main transmission vector was Anopheles sinensis for malayan filariasis, and Culex quinquefasciatus for bancroftian filariasis. The provincial control program have conducted since 1972. Repeated blood examinations and systematic DEC treatment of microfilaremia as well as mass chemotherapy and DEC—medicated salt administrations in villages with heavy prevalence,were carried out. By 1988, the microfilarial rate in the province has been reduced to 0. 08 % and the rate in a village as an unit was reduced to less than 1%. In October of 1990, Chinese Ministry of Public Health organized a re — examination group to review the control program and ascertained that filariasis was basically eliminated in Jiangxi province.
