摘要
Serum samples were collected from 353 heroin addicts in Linchang Prefecture and Kunming Area, Yunnan Province for detecting anti-HIV with ELISA and Western Blot, and 319 of them also for detecting various infection markers of hepatitis A, B, C and D with ELISA. Results showed no anti-HIV was found among them, overall infection prevalence rate of hepatitis A, B, C and D was 78.11%, 72.73% for males and 90.91% for females, and 1.57%, 63.97%, 51.85% and 5.79% positive rates for anti-HAV-IgM, HBV markers, anti-HCV and HDAg and/or anti-HD-IgM, respectively. Prevalence of mixed infection with different types of hepatitis was 40.07%, and 35.35% for mixed HBV and HCV. Infection rate of hepatitis B and C in Kunming Area was significantly higher than that in Linchang Prefecture, and so did in Han nationality than in other minority nationalities. It suggests hepatitis viruses infection is caused by drug abuse, use of non-sterilizing syringes with others.
