[Research on risk factors of 5 types of viral hepatities among population with high risk behaviors].
Epidemiological and serological survey on five types of viral hepatities (hepatitis A-hepatitis E) was conducted from October 1994 to December 1996 among 119 labourers returned from abroad, including 55 female prostitutes, 86 medical workers, 88 STD patients and 88 paid blood donors. HAV infection rates for all of the 5 groups were above 83%. HBV infection rate showed significantly different (chi 2 = 3.86, P < 0.05) between medical workers (53.49%) and the control group (30.43%). A significant difference (chi 2 = 5.36, P < 0.05) between HBV infection among prostitutes (52.73%) and control group (26.67%) was also noticed. In all the five groups, none was found to be anti-HDV positive. The HEV infection rates for the medical workers, prostitutes, blood donors, returned labourers and STD patients were 1.16%, 3.64%, 2.27%, 5.88% and 6.82%, whereas the anti-HCV positive rates were 1.16%, 3.64%, 0.00%, 0.00% and 1.14%, among them respectively.
