Objective To evaluate the infection rate and influencing factors of Hepatitis E Virus among different occupational population in nanjiang region of Xinjiang. Methods A cross-sectional survey was carried out in occupational population and non-occupational population having a close contact with livertock. Serum IgG antibodies against hepatitis E virus was tested by indirect enzyme-linked immunosorbent assay , and logistic regression model was used to analyze the risk factors of HEV infection. Results The result showed that the total positive rate was 51.88% and 317 out of 611 subjects were anti-HEV IgG positive. Non-occupational population had the lowest positive rate (35.90%), followed by the stock man of intensive nursery (24.14%), stock man of scattered nursery (76.00%), livestock and meat salesperson (79.37%) and slaughterman (81.53%). Multivariate logistic regression analysis showed that close contact with livestock , eating out and without frequent hand washing increased the risk of HEV infection . And HEV infection rate decreased in the population with professional training. Conclusion It is noticeable that promoting good health habits and cutting off animal-contact transmission are effective measures for the prevention of hepatitis E.
