Tracking people with both hepatitis B and Delta infections

This is a long-term tracking study for people who have both hepatitis B and Delta virus infections at the same time. Researchers will monitor your health regularly and collect blood samples to build a research database that helps them better understand how these two infections affect people and how different treatments work.

Having both hepatitis B and Delta infections together is particularly serious and complex, but there is limited data on how people manage this co-infection over time and how well different treatment approaches work. This study aims to fill that gap by carefully following patients and learning from their real-world experiences.
