Epidemic factors and control of hepatic echinococcosis in Qinghai province.
Hepatic echinococcosis, also called echinococcosis, is a health-threatening disease commonly found in pasture, and belongs to parasitic zoonoses. The purpose of this study was to investigate the prevalence and the risk factors of echinococcosis in Qinghai province in order to provide fundamental data for prevention and control of echinococcosis in Qinghai province. A total of 23 445 people from 21 counties were enrolled in this study by multi-stage stratified random sampling. Echinococcosis was diagnosed by using B-mode ultrasonography and serological tests. The results showed that the prevalence of echinococcosis was 4.47% (95%CI: 4.21%-4.73%) and serum positive rate (seroprevalence) was 15.47% (95%CI: 14.92%-16.02%) in 2010. The distribution of echinococcosis differed in age, sex, ethnicity, occupation and regions in Qinghai (P<0.05). GLMM analysis revealed that gender (female vs. male), ethnicity (Tibetan vs. other ethnicities), profession (herders vs. other professions) and region (autonomous prefectures vs. cities) were significant risk factors for echinococcosis (P<0.05). It was concluded that the prevalence of echinococcosis in 2010 was about 4% in Qinghai province, and the distribution of echinococcosis in Qinghai was associated with age, sex, ethnicity and profession.
