我县于1979年基本消灭血吸虫病,1980年还查出近10万m~2有螺面积,其中99％分布于半山丘陵地区(地面海拔15～35m,山峰海拔370～1000m)。1981年以后,采取了多层次查螺,巩固性灭螺和建立查灭螺责任制等措施,取得了比较明显的效果。1983年,有螺面积减少为6315m~2,比1980年减少了93.5％。 In 1979, the county basically eliminated schistosomiasis. In 1980, nearly 100,000 m 2 of snails were found, of which 99% were found in the mid-mountain and hilly areas (15 to 35 m above sea level and 370 to 1,000 m above sea level). After 1981, a series of measures such as checking snails at multiple levels, consolidating snails and establishing a responsibility system for snail control have been adopted and relatively obvious results have been achieved. In 1983, there was a reduction in the area of ​​6315m ~ 2, a decrease of 93.5% over 1980.
