Markers for hepatitis A, B and C in methadone maintained patients: An unexpectedly high co-infection with silent hepatitis B
Hepatitis, Viral, Human
Most methadone-maintained subjects had at least one marker for viral hepatitis, with 41.8% having markers for HAV, HBV and HCV. A quarter of subjects had silent HBV infection, defined as the presence of HBV DNA in the absence of HBsAg. These subjects should be considered infectious and pose a public health risk.
