1989～1996年湖北省丝虫病监测结果与分析

为探讨基本消灭丝虫病后丝虫病的流行动态和残存微丝蚴血症者的传播作用 ,从 1989年开始在全省范围内开展了丝虫病横向监测和纵向监测。 1989～ 1996年 ,全省共监测 12 37871人 ,查出微丝蚴血症者 140例 ,其中 ,1989～ 1993年的年微丝蚴率分别为 0 .0 5 %、0 .0 2 %、0 .0 1%、0 .0 1%和 0 .0 0 4% ,从 1994年以后未发现微丝蚴血症者 ;解剖蚊媒 8995 7只 ,从 1993年以后 ,未发现蚊媒人体幼丝虫。结果提示 ,湖北省的丝虫病传播已被阻断

RESULTS AND ANALYSIS OF FILARIASIS SURVEILLANCE IN HUBEI PROVINCE FROM 1989 TO 1996

To study the situation of filariasis after basic elimination and the transmissive effect of the residual microfilaemia, we carried out a cross and longitudinal surveillance from 1989 to 1996, and examined 1 237 871 persons, as a result, 140 mocrofilaemia cases were detected in the surveillance areas. Yearly microfilaremia rate decreased from 0.05% in 1989 to 0.004% in 1993 and no microfilaremia cases were found after 1994. In the same period, 89 957 mosquitoes were dissected and 3 positive mosquitoes were found. No infectious larvae were found in mosquitoes after 1993. The results showed that filariasis transmission has been interrupted in the Province.
