摘要
浙江省余杭县莫家桥村子1983年基本控制丝虫病后,继续进行了流行病学纵向监测。1984～1988年监测结果,人群微丝蚴阳性率和抗体阳性率分别由1983年的1.03%和30.43%下降为1988年的0和2.63%;原有微丝蚴血症者在3～5年内转为阴性;蚊媒幼丝虫自然感染率由1983年的0.07%下降为988年的0;10岁以下儿童血检微丝蚴及 ELISA 检测均未发现阳性者。表明当地己阻断了丝虫病的传播。根据上述结果,提出了消灭丝虫病的技术标准并对有关问题进行了讨论。
A longitudinal epidemiological surveillance has been carried out since filariasis was controlled in 1983 in Mojiaqiao village of Yuhang county,Zhejiang Province.The results of surveillance revealed that the prevalence rate of microfilaremia and antibody positives rate of sera by ELISA_ in the population decreased from 1.03% and 30.44% in 1983 to 0% and 2.63% in 1988 respectively.The residual microfilaraemia cases became negative within 3—5 years;natural infection rate of the mosquito vectors redu- ced from 0.07% (1983) to 0% (1988).Neither microfilaremia nor sero-positive case was found in children under 10 years old by blood examination or ELISA technique. From these data,it can be seen that the transmission of filariasis has been interrupted in the study area.Therefore,a technical criterion protocol for filariasis eradication is put forward and relevant problems are discussed.
