Researchers are evaluating a screening method for hepatitis B, hepatitis C, and AIDS viruses among drug users. The study aims to identify active infections of these viruses using a simple blood collection technique. It focuses on individuals with a history of intravenous or nasal drug use, including those receiving opiate substitution therapy. The study uses a Dried Blood Spot method for blood collection to screen participants for hepatitis B, hepatitis C, and AIDS viruses. This approach allows for easier sample collection and testing in this population. The intervention involves collecting blood samples on special filter paper to detect active infections. Participants are involved in one screening visit where their blood is collected using the Dried Blood Spot method. Researchers will assess the presence of active hepatitis B, hepatitis C, and AIDS infections on the first day. The study monitors the number of individuals with active infections as primary outcomes. The total participation time is focused on this initial screening event.
