采用病例查询和重点人群血清PVC薄膜快速酶标检测相结合,于1990-1991年对河北省人体囊虫病、包虫病、肺吸虫病和旋毛虫病进行了线索性调查。囊虫病例分布于全省77.78％的地区、省辖市和53.96％的县。重点人群血清学阳性率为2.01％。包虫病例及血清学阳性者见于北部高原山区以畜牧业为主的县,其中所查各县血清学阳性率在0.29％—0.71％之间。肺吸虫病1例病人见于沿海地区的海兴县。血清学阳性者见于海兴县、黄骅市和涉县,阳性率在1.32％—2.08％之间。旋毛虫病血清学检测31个县,检出阳性12个县,阳性率范围为0.44％—3.29％。
A case-by-case survey was carried out in combination with the rapid enzyme-linked detection of serum PVC membrane in key populations. A linear investigation was performed on human cysticercosis, hydatid, paragonimiasis and trichinosis in Hebei Province from 1990 to 1991. Cysticercosis cases located in the province 77.78% of the area, provincial cities and 53.96% counties. Key population serological positive rate was 2.01%. Echinococcosis cases and seropositive were found in the northern plateau mountainous areas mainly in animal husbandry, of which counties counties serological positive rate was between 0.29% -0.71%. A case of paragonimiasis was found in Haixing County, a coastal area. Serological positive found in Haixing County, Huanghua City and Shexian, the positive rate was between 1.32% -2.08%. Serological detection of Trichinella in 31 counties, 12 positive counties detected, the positive rate range of 0.44% -3.29%.
