摘要
在垸内水网型疫区对1018名当地居民进行KatoKatz法、孵化法检查、间接血凝试验(IHA)、B超检查和病史询问,并调查当地的螺情,以了解血吸虫病疫情,结果显示:阳性螺密度达0099只/011m2,居民粪检阳性率4476%,IHA阳性率6252%。B超检查显示该地人群血吸虫病引起的肝脾慢性损伤也相当严重。提示:垸内水网型疫区具有特有的流行环境,该地区的疫情控制应引起足够重视。研究还显示:该疫区的日本血吸虫病无明显的家庭聚集性。KatoKatz法与尼龙绢集卵孵化法合用能大大提高检出率,间接血凝实验只有作辅助诊断方法。B超诊断血吸虫病引起的肝脾异常的标准有待改善。
In dam circle marsh region,the authors examined nearly one thousand residents by Kato Katz′s method,hatching method,IHA and Ultrasound to learn the prevalence of schistosomiasis and also survey the snail density in that area.Result showed that the positive snail density was 0 099 per 0 11m 2.Positive rate of fecal examination and IHA was 44 76% and 62.52%.The liver and spleen abnormalities caused by schistosomiasis were also very serious.It shows that much attention should be paid to control the morbidity of dam circle marsh region because of its unique epidemic environment.It also shows that there is no familial aggregation of schistosomiasis in that area.Much more patients can be checked out if Kato Katz and hatching methods are used together.IHA can only be used to diagnose as an auxiliary method.The standards of liver and spleen abnormalities diagnosed byb ultrasound should be improved.
