1974～1977年,广东省阳山县犁头镇以单一查治措施防治班氏丝虫病。防治前人群微丝蚴率为15.08％,致倦库蚊自然感染率为9.33％。经4年4次查治后,微丝蚴率降为 0.45％,来发现致倦库蚊自然感染。防治后12年,分层随机抽样进行远期效果观察,血检5711人,解剖致倦库蚊672只,未发现微丝蚴血症者和蚊媒感染。结果表明,单一查治措施防治班氏丝虫病的效果巩固,即使个别村残存低密度微丝蚴血症者较多(2.67％),仍不引起流行传播,且微丝蚴血症者逐年转阴。
1974 ~ 1977, Yangshe County, Guangdong Province, a single investigation and treatment measures to control Bancroftian filariasis. Pre-control crowd microfilaria rate of 15.08%, Culex pipiens pallens natural infection rate was 9.33%. After 4 years of investigation, the microfilariae rate dropped to 0.45%, to discover the natural infection of Culex quinquefasciatus. Twelve years after the prevention and treatment, stratified random sampling was used to observe the long-term effects, 5711 blood tests and 672 anatomy of Culex pipiens pallens were found. No microfilaremia and mosquito infections were found. The results showed that the single investigation and treatment measures to control the effect of Bancroftian filariasis consolidation, even if the individual village residual microfibre microfilaria are more (2.67%), still does not cause the spread of epidemic, and microfilariaemia each year Negative.
