摘要
目的了解不同流行程度疫区IHA和Kato-Katz法血吸虫感染检出率之间在的相关性。方法随机选择湖沼型的高度流行村(感染率>10%)、中度流行村(感染率5%～10%之间)、低度流行村(感染率1～5%之间)各2个自然村,每村整群抽样300～500人,在感染季节后,对每人同时采用Kato-Katz法和IHA法检测。结果在受检的1831人中Kato阳性率16.66%、IHA阳性率28.18%、双阳性率6.28%。结论IHA的阳性率与血吸虫卵粪便检出率不相关,而IHA的阳性预测值与其成正相关关系,即随着地区疫情程度的加重,IHA法的筛查阳性率也随之升高。
Objective To investigate the the relationship of detectable rates for schistosomiasis between the techniques of IHA and Kato-Katz in different endemic areas. Methods 6 villages, two villages in high epidemic （infection rate of moer than 10% for villagers ）,two villages in medium epidemic （infection rates between 5%-10% for villagersw ） and two villages in low epidemic （infection rate of less than 5% in villagers）, were randomly selected, and 300 to 500 villagers in each villages were examined with both techniques of IHA and Kato-katz at the same time. Results There was positive rate of 16.6% in Kato-Katz technique, and that of 28.2% in IHA, and that of 6.3% of both Kato-katz and IHA in 1 831 villagers detected. Conclusion There was no relationship of detectable rates for schistosonfiasis between the techniques of IHA and Kato Katz. But there was positive correlation between the positive prediction value of IHA and detected rates of Kato-Katz, namely, with the increasing of that of kato-katz, with increase of epidemic, infection rates detected in IHA were increased.
