四川省丝虫病防治后期晚期丝虫病患者调查

在四川省丝虫病防治后期(1986～1996年),于班氏丝虫病区和马来丝虫病区分别累计检出晚期丝虫病患者49504例和903例，患病率分别为2.00％和0.17％。班氏丝虫病晚期体征中鞘膜积液、乳糜尿、象皮肿和混合体征人数分别占72.30％、25.96％、0.95％和0.79％，25岁以上年龄组检出率随着年龄的增长而增高。鞘膜积液和象皮肿的病程均以11～20年较多；乳糜尿患病率女性较男性为高，病程1～5年为多,显示在防治后期新发病例以乳糜尿为主，鞘膜积液和象皮肿的发生基本趋于控制。马来丝虫病象皮肿体征男性多于女性，以50～69岁年龄组最多，19岁以下未检出象皮肿患者，病程大多>21岁，表明已无新发象皮肿病例出现。

SURVEY ON PATIENTS WITH CHRONIC FILARIASIS IN LATE STAGE OF CONTROL PROGRAM IN SICHUAN PROVINCE

During 1986-1996, the late stage of filariasis control program in Sichuan Province, a total of 49 504 bancroftian and 903 malayan chronic filariasis cases were accumulatively detected out in relevant endemic areas of Sichuan. Among the bancroftian cases, the chronic signs of hydrocele, chyluria, elephantiasis and mixed type accounted for 72.30%, 25.96%, 0.95% and 0.79 % respectively. In >25 years old age group, the cases with chronic signs revealed upward trend as the age increased.
