用PVC板Dot－ELISA在青南高原进行了人群白虫病的流行病学调查，结果表明，人群包虫病血清阳性率为16．01％，男性和女性分别为13．13％和18．89％，女性高于男性。牧民、半农牧、僧侣、干部、学生、农民及其他职业人鲜血清阳性率分别为20．27％、16．20％、1250％、10．41％、7．63％、5．71％、12．80％，以牧民的血清阳性率最高。随年龄的增加，人群包虫病血清阳性率越高（P＜0．01），～10岁为3．25％，～20岁为13．06％，～30岁为16．27％，～40岁为16．49％，～50岁为21．18％，～60岁为23．66％，～70岁为24．72％，～80岁为44．00％。经统计学检测，男性与女性、不同职业人群及各年龄段人群包虫病血清阳性率之间存在显著性差异（P＜0．01）。PVC-Dot-ELISA操作简便，成本低廉，快速直读，适于基层诊断应用和进行大规模流行病学调查。
Epidemiological survey of human white worm disease was conducted in the Qingnan Plateau using PVC plate Dot-ELISA. The results showed that the positive rate of human hydatidosis was 16.01%, and the male and female were 13.13% and 18.89 %, Women than men. The positive seroprevalence of herdsmen, semi-peasants, monks, cadres, students, peasants and other professionals was 20.27%, 16.20%, 1250%, 10.41%, 7.63%, 5.71% , 12.80%, the highest positive rate of herdsman seropositivity. As the age increased, the positive rate of hydatid disease in the population was higher (P <0.01), 3.25% at 10 years old, 13.06% at 20 years old, 16.27% at 30 years old, 16.49% at age 40, 21.18% at age 50, 23.66% at age 60, 24.72% at age 70, and 44.00% at age 80. There was a significant difference (P <0.01) between the seroprevalence of hydatid disease in men and women, different occupational groups and all age groups. PVC-Dot-ELISA is easy to operate, low cost and fast direct reading, suitable for primary diagnosis applications and large-scale epidemiological investigation.
