摘　　要：目的：了解丝虫病防治后期中华按蚊传播马来丝虫病的作用及丝虫病流行病学特征。方法：在不进行任何防治的基础上，对马来丝虫病流行区４个试点村进行人群参数、蚊媒参数和免疫学参数的纵向观察。结果：３个试点村微丝蚴率逐年下降，已不足以构成传播，即水洼１９８２～１９８５年微丝蚴率分别为０．９７％、０．６３％、０．５５％、０．３７％，１９９８年为０．０５％，１９９０和１９９２年均为０。古柏门１９８６～１９８９年微丝蚴率依次为１．５５％、０．８４％、０．４２％和０．３１％；黄垸１９９０～１９９４年为０．７２％、０．３０％、０．０８％、０．０８％、０．０８％；而莫市微丝蚴率无明显变化，维持在２．３％左右，１９８６～１９８９年依次为２．３１％、２．２３％、２．３０％和２．４３％。水洼于１９８２年蚊媒感染期幼丝虫率０．４６％，１９８３年为０．１０％；莫市媒介感染期幼丝虫率１９８７年为０．０９％，１９８８年为０．１９％。黄垸血清阳性反应率逐年下降，与血检结果相一致。结论：以中华按蚊为单一传播媒介的马来丝虫病流行区，其丝虫病传播的微丝蚴率临界水平为１．５％～２．３％；在达到基本消灭丝虫病地区，马来丝虫病传播流行呈下降态势，防治措施可以?A longitudinal study on prevalence trend of malayan filariasis and role of transmission filariasis by Anopheles sinensis have beed carried out in endemics with A.sinenses as only vector from 1982 to 1994 in Hubei province,China.Microfilarial rate (MFR),microfilarial density (MFD),vector parameters and IFA,ELISA,Dot-ELISA have been collected without any control measures in 4 villages. The results showed that MFR was down year by year and transmission was interrupted in three villages in which MFR in Shuiwa village be 0.97 % in 1982, 0.63 % in 1983, 0.55 % in 1984, 0.37 % in 1985, 0.05 % in 1989,0 in 1990 and 0 in 1991; 1.55 %, 0.84 %, 0.42 % and 0.31 % in 1986-1989 in 1989,0 in 1990 and 0 in 1991; 1.55 %, 0.84 %, 0.42 % and 0.31 % in 1986-1989 respectively in Gobaimen village; 0.72 %, 0.30 %, 0.08 % and 0.08 % in 1990-1994 in Huangyuan village respectively.However,MFR without different changes in Moshi village were 2.31 %, 2.23 %, 2.30 % and 2.43 % in 1986-1989 respectively. An.sinensis harbouring infection larvae rate were 0.48 % in 1982, 0.10 % in 1983 in Shuiwa; 0.09 % in 1987, 0.19 % in 1988 in Moshi.The serological positive rate was induced year by year as MFR's.It concluded that 1.5 %- 2.3 %MFRis crisis level for transmission in malayan filariasis where A.sinensis as an only vector;the MFR dropped to bellow 1% after control, there was no indication the rate would upgrade during the survey period, no control measure be needed.A decline trend of the transmission of malayan filariasis,therefore,has been exhibited.
