【摘要】 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的传播作用，１９８４－ １９９３年连续十年对原高、中度流行区的１８ 个村进行纵向监测，结果人群微丝蚴率和密度逐年下降，分别由 １９８４ 年的 ０１７％ 和 １４２ 条／１２０μｌ，下降至 １９９１ 年的 ００３４％ 和 １２ 条／１２０μｌ，微丝蚴阳性村于第 ２－ ９ 年降为０。３２ 例微丝蚴血症者，均于 ３－ ６ 年内全部自然转阴。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。年传播潜势呈明显下降，在 １９８８－ １９９３年间除 １９９１ 年年传播潜势 ０１２ 外，其余年份均为 ０，结果提示，我省丝虫病传播已被阻断更多还原

【Abstract】 To investigate the epidemiological dynamic of filariasis and transmission role of residual microfilaremia patients after filariasis being basically under control, a longitudinal surveillance has been carried out in 18 villages classified previously as hyper and meso endemic areas from 1984 to 1993 successive 10 years. The results showed that the microfilarial rate and density in population decreased year by year i.e. from 0.17% and 14.2 mf/120μl in 1984 dropped to 0.034% and 1.2 mf/120μl in 1991.The village with microfilaremia case dropped to 0 at the 2nd-9th year and all the 32 microfilaremia cases converted naturally into negative at the 3rd-6th year after filariasis being basically under control. In 6 years since 1988, no positive mosquito has been found except 3 mosquitoes with I stage larva found in patient’s houses in 1991. The annual transmission potential revealed remakable decline and all the transmission potential became 0 during 1988 to 1993 except 0 12 in 1991, demonstrating that filariasis transmission has been interrupted in Shandong Province.更多还原
