1987～1991年在基本消灭班氏、马来丝虫病地区,进行了人群流行病学监测。一、材料与方法 1.微丝蚴血症调查.对5岁以上人群进行血检,取耳垂血6大滴(相当120μl),常规染色镜检。对查出微虫蚴血症者不予治疗,并进行流行病学个案调查,建立个案表,定期复查。 2.蚊媒调查在6～9月,对班氏(每年)和马来(连续3年)丝虫病地区各选一个考核前微丝蚴率较高的自然村,定人、定时、定点于20:00～22:00时室外人诱捕蚊和次日凌晨用口吸管捕光50顶蚊帐,待蚊胃血消化后解剖,并计算叮人率。二、结果 1.微丝蚴率及密度 5年调查188个村,阳性村
From 1987 to 1991, population epidemiological surveillance was conducted in areas where Bancicilli and Malayi were basically eliminated. First, the material and methods 1. microfilariaemia investigation.Of 5 years of age above the blood tests, take the ear drop blood 6 drops (quite 120μl), conventional staining. On the detection of micro-parasitemia who are not treated, and epidemiological case investigation, the establishment of case tables, regular review. 2. Mosquito vectors survey From June to September, natural villages with high rates of microfilariae prior to examination in each of Bandz (each year) and Malay (3 consecutive years) filariasis areas were selected and scheduled to be fixed at regular intervals 20: 00 ~ 22: 00 outdoor trapping mosquitoes and the early morning of the next morning with mouth tube light 50 top mosquito nets, to be mosquito stomach digestion after dissection, and calculate the bite rate. Second, the results 1. Microfilaria rate and density of 5-year survey of 188 villages, positive village
