摘要
江汉平原为我国范围最大的单纯以中华按蚊为媒介的马来丝虫病流行区,仙桃市位于江汉平原的中部,该市在基木消灭马来丝虫病后三年,血检调查40个村,检出微丝蚴血症100人,平均微丝蚴率0.22％,相对集中在原微丝蚴率5％以上的村,35％的微丝蚴血症者年龄在30～45岁之间,且以男性为多,绝大多数血症者近十年未接受任何防治措施。纵向观察1个村,共血检微丝蚴血症者26人,4年微丝蚴率依次为1.55％、0.84％、 0.42％、0.31％,有逐年下降趋势;2～3年持续阴转20人;3年中华按蚊自然感染率依次为0、0.08％、0,1～10岁儿童未出现新感染。
Jianghan Plains was the endemic area for Brugia malayi filariasis and Anopheles sinensis was the main vector responsible for the disease. Xiantao City locates in the middle of the plains and 100 microfilaremias were det-ected with an average microfilarial rate of 0.22% in the 40 villages exa-mined 3 years after malayi filariasis was basically eliminated in this city. The mirofilcaremias were relatively concentrated in the villages previously with a microfilarial rate of over 5%. Most of the microfilaremias were males and 35% of the total microfilaremias aged between 30-45 years. In addition, no DEC therapy were given to most of them. In a longitudinal study conducted in a village, 26 microfilaremias were detected through blood examination and the microfilarial rates in the previous 4 years were 1.55%, 0.84%, 0.42% and 0.32% respectively with a tendency of decrease year by year. Twenty cases out of the 26 microfilariaemias became negative in 2-3 years and the natural infection rates of Anopheles sinensis were 0, 0.08% and 0 in the last 3 years. No new infections were found in the children aging between one to 10 years.
