摘要
山东省于１９８３年基本消灭丝虫病后，１９８４～１９９３年连续１０年对原高、中度流行区的１８个村进行纵向监测，人群微丝蚴率和密度逐年下降，分别由１９８４年的０．１７％和１４．２ｍｆ／１２０μｌ，下降至１９９１年的０．０３４％和１．２ｍｆ／１２０μｌ，１９９２～１９９３连续２年未发现微丝蚴血症者。观察３２例微丝蚴阳性者，均于３～６年内全部自然转阴。１０年中蚊虫平均自然感染率０．０４％（１５７／３８２５４９），１９８８年以来６年中除１９９１年在病家发现含Ⅰ期幼丝虫蚊３只外，各年均未发现阳性蚊。结果表明，达到基本消灭后，年传播潜势呈明显下降，在１９８８～１９９３年间除１９９１年年传播潜势为０．１２外，其余年份均为０。
Through
successive ten years longitudinal surveillance of filariasis(1984-1993)a-mong 18 villages with
previously high and moderate endemics in Shandong Province,in 14 vil-lages with
microfilaremia rate of 0.07%-1.15%and microfilaria density of 1-50 mf/120μl in1984 the
microfilaremia rate dropped down to zero in 2-9 years.Annual quantitative blood ex-amination of
32 mf-positive cases showed all the case became negative naturally in 3-6 years.The ten year
surveillance of Culex pipiens pallens demonstrated that the natural infection ratewas
0.04%(157/382549)in average.After 1988 no any positive mosquito was found except
3mosquitoes captured in patients’dwelling in 1991.
