摘要
对韶关市及其所辖班氏丝虫病流行县进行病原学、血清学及媒介昆虫学的纵向观察和横向调查。血检５３２６８人，占流行区人口的１０．２６％，发现微丝蚴血症３例，平均微丝蚴率０．００６％。选择丝虫病流行较严重的乐昌县和乳源县进行纵向观察，人群微丝蚴率和蚊媒自然感染率均逐年下降。人群丝虫抗体阳性率从１９８６年的５２．８２％降为１９９０年的５．８０％，表明韶关市及所辖各县的班氏丝虫病传播已被阻断，基本消灭丝虫病后所残存的少数低微丝蚴密度患者已起不到传染源作用，因此可终止大规模综合性防治工作，加强监测则可达到消灭丝虫病目的。
The bancroftian filariasis has been basically eliminated in 1983 all over Shaoguan City including 6 endemic counties under jurisdiction of this city. Henceforth, the control measures had been stopped. Since 1986, the longitudinal observation of vector, serology and aetiology was carried out, The results showed that the microfiarial rate and natural infection rate of Culex quinquefascratus were come down Year by Year, and the Positive rate of filarial antibody from 52. 82% in 1986 dropped to 5. 80% in 1990. While the laitudinal survey was conducted. 3 cases with microfilariae were found from 53268 persons examined. the microfilarial rate was 0.006%. The results mention above indicated that the filariasis prevalence and transmission had been interrupted, and the large scale control campaign was no need to conduct. The filariasis will be eradicated if strengthening the surveillance.
