在经防治后以中华接蚊为媒介的低微丝蚴率和低密度的马来丝虫病流行区的三个村．进行了丝虫病传播状况观察。观察期间，每年对试点村人群进行血检．检出的微丝蚴血症者仅用维生素Ｃ安慰治疗，同时收集蚊媒各项有关参数，计算年叮人率和年传播潜势。结果显示：微丝蚴率低于１．５５％、微丝蚴密度小于１５条／１２μｌ，不再采取任何防治措施、丝虫病传播已停止；微丝蚴率为２．３１％，微丝蚴密度大于２２条／１２０μｌ时，其微丝蚴率仍在原水平徘徊。
The three villages with endemic microfilaria and low-density endemic areas of Malayan filariasis, which were controlled by Chinese mosquitoes, were used as controls. Filariasis transmission was observed. During the observation period, blood tests will be conducted on the pilot village every year. Microfilaria were detected only vitamin C comfort treatment, while collecting mosquito vectors of the relevant parameters, calculate the rate of annual bites and annual transmission potential. The results showed that the rate of microfilariae was less than 1.55% and the density of microfilariae was less than 15 per 12μl. No further measures were taken to prevent the transmission of filariasis. The rate of microfilaria was 2.31% When the density of larvae is more than 22 / 120μl, the microfilariae rate remains at the original level.
