ABSTRACT

Objective:To investigate the infection status and influencing factors of hepatitis E virus infection among different occupational populations in Xinjiang region,and to provide a available evidence for control of hepatitis E.Methods:A randomly sampling survey was carried out in the population of public health practitioners, the serum IgG antibodies against hepatitis E virus in 1 720 samples were tested by indirect enzyme-linked immunosorbent assay,and the experimental data was analyzed with SPSS 19.0 software;the differences of infection rates between genders,ages and occupations were analyzed.Results:Among 1 720 subjects,440 persons were anti-HEV IgG positive,and the total positive rate was 25.58%;the positive rate of males (27.99%)was higher than that of females (23.35%),and the IgG positive rate was increased along with the age;there were significant differences of the anti-HEV-IgG antibody positive rates between the populations with different ages (χ2 =118.262, P = 0.000 ). There was a statistically significant difference of infection rate of hepatitis E between different occupational populations (χ2 = 98.262,P = 0.000),the slaughterman had the highest positive rate (81.53%), followed by the livestock and meat salesperson (79.37%),food service population (30%),supermarket population (11.21%)and others (9.03%).Conclusion:The hepatitis E infection rate is high among the public health practitioners in Xinjiang region,and occupation,age and gender are the major influencing factors of hepatitis E infection rate.
