沿河县属黔东北山区,原属班氏丝虫病高度流行区,全县微丝蚴阳性率24.2%,致乏库蚊自然感染率27.3%。经过1970—1975年普查普治和全民食用0.3%海群生食盐6个月,1976年微丝蚴阳性率降到0.3%达到基本消灭丝虫病的标准。为了评价防治效果,监测流行动态,1977—1984年连续8年对残存传染源和媒介传播作用进行了纵向和横向观察,现将观察结果报告如下:
Yanhe County is a mountainous area in northeast of Guizhou Province, which belonged to a highly endemic area of Bancroftian filariasis. The positive rate of microfilariae in the county was 24.2%, and the natural infection rate of Culex pipiens pallens was 27.3%. After the 1970-1975 General Survey and the universal consumption of 0.3% of the sea of raw salt 6 months, in 1976 the microfilaria positive rate dropped to 0.3% to basically eliminate filariasis criteria. In order to evaluate the effectiveness of prevention and treatment and to monitor the epidemic dynamics, longitudinal and horizontal observations of the residual sources of transmission and media transmission were conducted for the 8 consecutive years 1977-1984. The observations are reported as follows:
