目的观察新洲居民迁移对血吸虫病流行的影响。方法采用纵向观察法,对新济洲居民迁移前后人群病情和当地螺情的变化情况进行调查分析。结果三年多的观察表明,新济洲居民迁移后,外迁居民血吸虫病感染率呈逐年下降趋势,并未造成新迁居地当地的疫情的回升与扩散,而留居在当地人群的血吸虫感染率呈上升趋势,并且洲上仍有感染性钉螺存在。结论在防治措施的干预下,血吸虫病疫区居民的迁移可避免疫情的扩散,并能保护居民的健康。
Objective To observe the impact of residents relocation on schistosomiasis prevalence in Xinzhou. Methods Longitudinal observation was used to investigate the changes of the population and the local snail before and after the relocation of residents in Xinjizhou. Results The results of more than three years showed that after the relocation of residents in Xinjizhou, the infection rate of schistosomiasis for relocated residents showed a declining trend year by year, which did not cause the rise and spread of the epidemic in the newly relocated area. However, the schistosomiasis infection in the local population The rate is on the rise, and there are still infectious snails in the continent.
