HIV Co-infection with Hepatitis A – the length of time someone is sick with Hepatitis A can be increased if the person is HIV positive. The illness might also be more severe. If someone is HIV positive, the hepatitis A vaccination might not last as long and people might have to get vaccination boosters more regularly.
HIV Co-infection with Hepatitis B – HIV can speed up the progression of Hepatitis B if you are co-infected with both viruses. Also, if you are HIV positive and get the Hepatitis B vaccinations it might not last as long as if you were HIV negative.
HIV Co-infection with Hepatitis C – HIV speeds up liver damage and the progression of Hepatitis C. If someone is HIV positive it might be harder to diagnose if they have Hepatitis C. Having Hepatitis C can have an effect on how well medication might work for HIV.
