Surveillance and analysis of viral hepatitis among train attendants in Jiangxi province in 2013-2015

Objective To understand and analyze the prevalence of viral hepatitis in railway passenger occupational population in Jiangxi province, and to explore its epidemiological characteristics, so as to provide basis for the prevention and control of viral hepatitis in railway occupational population in the future. Methods The test results of anti-hepatitis A virus (HAV)-IgM, anti-HAV-IgG, hepatitis B surface antigen (HBsAg), anti-hepatitis B surface antibody (anti-HBs), anti-hepatitis C virus (HCV), anti-hepatitis E virus (HEV)-IgM and anti-HEV-IgG in some passenger train attendants of Nanchang Railway Bureau from 2013 to 2015 were collected and analyzed by SPSS 19.0 and Excel 2007 software. Results The positive rate of anti-HAV-IgG was 90.6%-98.7% from 2013 to 2015, the positive rate of HBsAg was 6.6%-15.1%, the positive rate of anti-HCV was 0.2%-1.4%, the positive rate of anti-HEV-IgG was 16.1%-24.9%; the positive rate of anti-HEV-IgG was significantly different between men and women, and the positive rate of anti-HEV-IgG was 29.5%, 30.5%, 22.5% between 2013 and 2015. The positive rate of male was higher than that of female (22.3, 22.5, 13.8) (χ2=3.934, P=0.047; χ2 =4.363, P=0.037; χ2=6.755, P=0.009), and there was no significant difference between male and female in the surveillance results of other types of viral hepatitis. Conclusions The positive rate of intestinal transmitted hepatitis was high in the population and low in the acute phase. The positive rate of anti-HCV was low in the population with extraintestinal transmitted hepatitis. The positive rate of HBsAg was high in the population with extraintestinal transmitted hepatitis.
