OBJECTIVE: To understand the status of viral hepatitis infection among workers in iron and steel enterprises and their infection factors. Methods: A total of 213 males (62 males, 627 females, aged from 16 to 60 years) were enrolled in a systematic sampling of 2 013 workers in Anyang Iron & Steel Group Company for the detection of type 4 viral hepatitis infection markers and infection factors survey. Results: The infection rates of HAV, HBV, HCV and HDV were 58.22%, 52.0%, 22.4% and 1.94%, respectively. The positive rate of HBsAg was 84.9%. The prevalence of HAV was significantly related to age and history of foreign meals, with the increase of age or number of meals. The positive rate of HBsAg in men and women there is a significant difference, male over female, respectively, 9 74% and 6 70%. The infection rate of HBV has a significant relationship with the history of blood transfusion and the history of dental traumatology, which increases with the increase of the number of dental braces. Conclusion: Strengthening health supervision, reducing the frequency of foreign meals, strict blood management, control of iatrogenic infection, is the key to preventing hepatitis virus infection
