To analyzed the current situation of Echinococcus granulosus infection and risk factors of human cycstic echinococcosis in Hoboksar Mongolian Autonomous County of Xinjiang in 2013.

By using a cluster random sampling method, 532 inhabitants from 5 communes(pastures) of Hobukesar Mongolian Autonomous County, were screened by questionnaire, abdominal ultrasonic scan and serological test. Thirty-eight dogs were checked by autopsy and other 126 feces samples were collected and tested with Enzymes linked immunosorbent assay (ELISA).

The prevalence of human echinococcosis was 4.70% (25/532), including 4.32% (23/532) cystic echinococcosis (CE) and 0.38% (2/532) alveolar echinococcosis (AE). Seropositivity rate was 25.46% (125/491). Seropositivity rate in 41 - 65 years old inhabitants (30.70%, 66/215) was higher than that of 0 - 17 years old inhabitants (8.33%, 5/60, P < 0.05); female (30.19%, 93/308) was higher than male (17.03%, 32/183,P < 0.05); Mongolian (29.08%, 107/368) was higher than Han (13.79%, 4/29,P < 0.05); Narenhebuke(36.09%, 61/165) was higher than Bayinaowa (7.69%, 6/78, P < 0.05); and herdsmen (32.77%, 58/177) was higher than students (4.17%, 2/48, P < 0.05). Of the 38 dogs necropsied, 16 dogs were confirmed with Echinococcus spp infection under microscope. ELISA positive rate was 39.68% (50/126); ELISA positive rate in Narenhebuke 48.78%, 20/41) was higher than Chahete (20.00% , 4/20), but the difference was not statistically significant (P > 0.05). The overall average deworming rate of dogs was only 49.20% (62/126). Multivariate Logistic regression analysis showed that regions, occupations and genders were risk factors of human cycstic echinococcosis.

Our results have showed that the prevalence and seropositivity of echinococcosis are at high levels. The current study has showed that the main risk factors may be regions, occupations and genders.
