title: [Seroprevalence of viral hepatitis A, B and C in intravenous drug users].
abstract: Markers of viral hepatitis A-C of 99 intravenous drug users predominantly (in 96%) from the Karviná district were examined from March 1998 to February 1999. Pervitin (methamphetamine) was the basic drug in all subjects. Anti-HAV was detected in 6.4% of VHA non-vaccinated individuals, anti-HAV/IgM was not found in any case, HBsAg was detected in 4.0% (acute VHB was diagnosed in all these cases), anti-HBc in 9.2% and anti-HCV in 25.0% of the investigated cases. Our results confirmed the importance of drug use by injection, esp. needle sharing, for the spread VHB and VHC. In case of VHA the fecal-oral route of transmission in this subpopulation is dominant.
