目的 了解广东省斗门县输入血吸虫病人后是否可能形成血吸虫病的传播流行。方法对输入病例进行个案调查;对周围人群进行血吸虫病感染检查及钉螺孳生情况调查。结果仅发现4例输入性病例,没有发现当地感染病例;在5个镇的15个管理区共调查水渠边长度88 330 m,调查低洼荒地374 268.48 m2,未发现钉螺的孳生。结论 在斗门县等非血吸虫病疫区,只要及时治疗输入性病例,加强螺情监测,严防钉螺的输入,就不会形成血吸虫病流行。
Objective To understand whether the transmission of schistosomiasis could be formed after the introduction of schistosomiasis patients in Doumen County, Guangdong Province. Methods The cases were investigated on a case-by-case basis; the infection of schistosomiasis and the snail breeding in the surrounding area were investigated. Results Only 4 imported cases were found and no local cases were found. In 15 administrative areas in 5 towns, a total of 88 330 m of drainage ditches were surveyed and 374 268.48 m2 of low-lying wasteland were investigated. No snail breeding was found. Conclusion In Doumen County and other non-schistosomiasis-endemic areas, as long as timely treatment of imported cases, strengthen the snail surveillance, prevent snail input, it will not form a schistosomiasis epidemic.
