湖北省丝虫病监测

湖北省基本消灭丝虫病后１９８９～１９９４年横向监测６９个县（市）的１０９６个村，血检１１１５３０２人，查出微丝蚴血症者１４３人，平均微丝蚴率为０．０１３％，各年微丝蚴率依次为０．０２８％、０．０２５％、０．００８％、０．００６％、０．００４％、０．００２％。解剖致倦库蚊２６７２５只，未发现幼丝虫，解剖中华按蚊３２９６０只，仅１９８９年发现阳性蚊２只，１９９２年发现阳性蚊１只。血清学监测流行区人群平均抗体阳性率为２．０８％～２．７０％，与非流行区抗体水平相近，表明湖北省已有效地阻止了丝虫病的传播。

SURVEILLANCE OF FILARIASIS IN HUBEI PROVINCE

Cross sectional surveillance was carried out from 1989 to 1994 in 1096 villages of 69 counties in Hubei province, where filariasis had been basically eradicated. Among 1 115 302 persons surveyed, 143 microfilaremia patients were found by blood examination. The average microfilaremia rate(MFR) was 0. 013%,with the annual microfilaremia rates of 0.028%,0.025%,0.008%,0.006%,0.004%,and 0.002%from 1989 to 1994 respectively.No natural filarial infection was found in 26 725 Culex quinquefasciatus. Only 2 positive mosquitoes were found in 1989 and 1 positive mosquito was found in 1992 among 32 960 Anopheles sinensis. The average positive rate of filarial antibodies in inhabitants living in endemic area by IFAT ranged from 2.08%to 2.70%.There was no significant difference between the filarial antibody levels of inhabitants living in endemic and non-endemic areas. It was concluded that the transmission of filariasis in Hubei province was interrupted effectively.
