在洱源县重度流行疫区选择传播资源基本相同的4个白族自然村，共2000人，以村为单位随机分为A、B2组。进行基线调查，结果表明：A组血防知识及格率为48．20％、化疗覆盖率61．60％、人群感染率16．00％。B组血防知识及格率为54．20％、化疗覆盖率65．40％、人群感染率15．48％。在A组中对不同的目标人群用不同的传播途径进行健康教育和培训，B组采取一般防治措施。2年后进行效果评估结果为：A组血防知识及格率93．37％、化疗覆盖率93．35％、人群感染率5．18％。B组血防知识及格率55．83％，化疗覆盖率66．23％，人群感染率10．84％。A组人群感染率较B组下降52．21％，达到预期目标。
In the Eryuan severe epidemic endemic areas choose the same distribution of natural resources in the four white villages, a total of 2000 people, with the village as a unit randomly divided into A, B2 group. Baseline survey showed that: A group of knowledge of pass rate of 48.20% knowledge of blood, chemotherapy coverage 61.60%, population infection rate of 16.00%. The prevalence of blood-borne knowledge in group B was 54.20%, the coverage rate of chemotherapy was 65.40%, and the infection rate in the population was 15.48%. In group A, different target groups were given health education and training with different routes of transmission, while group B adopted general prevention and control measures. Two years later, the results of the evaluation were as follows: the pass rate of blood-protection knowledge in group A was 93.37%, the coverage rate of chemotherapy was 93.35%, and the infection rate in the crowd was 5.18%. The prevalence of blood-borne knowledge in group B was 55.83%, the coverage of chemotherapy was 66.23%, and the infection rate in the population was 10.84%. The infection rate of group A was 52.21% lower than that of group B, reaching the expected goal.
