摘要
在洲岛型日本血吸虫病重疫区,采用阳性病人选择性化疗的防治措施后,1989一1992年居民血吸虫感染率分别为39.6%、25.5%、30.6%和28.2%.1990一1992年的再感染率分别为22.6%、47.8%和40.0%,且人群的再感染与治疗前的感染度无关.再感染易感组和抗桔组人群平均年龄分别为17.2岁和24.4%岁.结果表明,单纯化疗后居民血吸虫再感染相当严重.
The reinfection with S. japonicum in residents with higher prevalence in island region, poyang lake,observed after selective treatment of positive cases had been taken since 1989. During 1989 ?992,the infection rates of residents were 39. 6% ,25. 5% ,30. 6% and 28.2% respectively,while the reinfection rates were 22. 6%,47. 8% and 40.0% during 1990?992, respectively. No relationship between population reinfection and intensity of infection prio to selective treatment was found. The average ages of resident population and susceptible population were 24. 4 and 17.2 years old,respectively. The results indicated that the reinfaction rate in residents was very high after single selective treatment in those areas.
