海群生药化食盐防治丝虫病研究

Study of Filariasis Control with Hetrazan Medicated Salt

目的 研究海群生药化食盐防治丝虫病效果 ,探讨防治丝虫病最有效、最经济的方法。方法 先查清各县 (市、区 )分乡 (镇 )微丝蚴率 ,然后分乡制定出海群生药化食盐的剂量 ,再按规定剂量送盐到户。结果 7县 1市 3区平均微丝蚴率由防治前的 0 .77%下降至 0 .16 %。海群生药化食盐防治丝虫病 ,具有效果好、副反应少的优点 ,比传统的反复普查普治方法节省防治时间 3～ 6年 ,节约防治经费 797万元 ;比普查后实施海群生药化食盐防治丝虫病的方法节约经费 2 4 0万元。结论 海群生药化食盐是防治丝虫病的有效、经济的方法。

Objective To explore most effective, economical way to control filariasis.Methods Microfilarial rate at various levels was investigated first. Then different dose of hetrazan medicated salt was worked out and sent to farmers. Results The results showed that microfilarial rate of 7 counties, 1 city and 3 districts was dropped from 0.77% to 0.16%. Conclusions Controlling filariasis had good effect and low side-effect. Compared with traditional control method, it could save a lot of time (3～6 years or so) and money (7.97 million Yuan). It also could save 2.4 million Yuan compared with common filariasis control with hetrazan medicated salt.
