INHSU is an international organisation dedicated to scientific knowledge exchange, knowledge translation, and advocacy focused on hepatitis C prevention and care for people who use drugs.

People who use drugs are disproportionately affected by hepatitis C. Further, the burden of hepatitis C-related disease in this group continues to grow at alarming rates and represents a major cost to the healthcare system. However, the majority of those affected are currently not adequately reached. Therefore, increasing hepatitis C testing, linkage to care, treatment and cure among people who use drugs is of paramount importance.
