目的进一步摸清基本消灭丝虫病后原流行区丝虫病流行病学特征，藉以为消灭丝虫病提供科学依据，评价丝虫病防治工作成效。方法在湖北省选择有代表性的丝虫病纵向监测点１０个进行病原学、蚊媒和血清学纵向监测。结果仅于１９８９～１９９０年发现１９例微丝蚴血症者，微丝蚴率分别０．０７１２％和０．０６６６％。蚊媒阳性率为０．０４５５％（１９８９）、０．０１９９％（１９９０）和０．０２１１％（１９９１）。血清学监测抗体阳性率由１９９０年的２８．５７％降至１９９４年的７．８６％。结论原丝虫病流行区经过防治达到基本消灭丝虫病标准后，通过监测人群微丝蚴率逐年下降，微丝蚴密度亦相应降低，残存微丝蚴血症者于基本消灭丝虫病５年内陆续转阴，证明我省基本消灭丝虫病的成果是巩固的，所采取的防治措施是行之有效的。消灭丝虫病于一个县市、一个地区，乃至全省及全国范围内是有望在短期内实现的。
Objective To further understand the epidemiological characteristics of filariasis in endemic endemic areas after the basic elimination of filariasis so as to provide a scientific basis for the elimination of filariasis and evaluate the effectiveness of prevention and control of filariasis. Methods Ten representative sites of filariasis surveillance in Hubei Province were selected for pathogenicity, mosquito detection and serological surveillance. Results Only 19 cases of microfilaremia were found from 1989 to 1990, with microfilament rates of 0.0712% and 0.0666%, respectively. The positive rates of mosquito were 0.0455% (1989), 0.0199% (1990) and 0.0211% (1991). The positive rate of serological surveillance antibody decreased from 28.57% in 1990 to 7.86% in 1994. Conclusion After the endemic filariasis epidemic area has basically reached the standard of eradicating filariasis, the microfilariae rate of the population declines year by year, and the density of microfilariae also decreases correspondingly. The remaining microfilaremia patients basically eliminate filariasis 5 The year after year turned negative, proving that the province basically eliminated the achievements of filariasis is consolidated, the prevention and treatment measures taken are effective. The elimination of filariasis is expected to be realized in a short time in one county, one region, and even the province and the whole country.
