[A study on the prevalence rates of human immunodeficiency virus, hepatitis B virus and hepatitis C virus infections in intravenous drug users].
OBJECTIVE
To study HIV, HBV and HCV infections in intravenous drug users.


METHODS
2025 blood samples from intravenous drug users were collected from Sichuan, Hunan, Guangxi and Xinjiang regions, and tested for anti-HIV, anti-HCV, HBsAg using enzyme-linked immuno-sobent assays (ELISAs).


RESULTS
The positive rates of anti-HIV,anti-HCV and HBsAg were14.7%-30.4%, 60.7%-85.5% and 6.6%-22.4% in the intravenous drug users, respectively. The co-infection rates of HIV/HBV, HIV/HCV, HCV/HBV and HIV/HCV/HBV were 0%-0.4%, 11.6%-27.2%, 2.3%-14.3% and 1.6%-4.8% respectively in this population.


CONCLUSIONS
The infection rates of HIV, HBV and HCV were higher in the intravenous drug users than that in general populations in the same regions, and HIV/HCV co-infection appeared most frequent in this population.
