Chronic hepatitis B virus infection is a common condition in Zambia. Among Zambian blood donors, up to 8% are chronically infected with HBV. Despite the burden, awareness of HBV is low in Zambia and the Ministry of Health is in early stages of development of guidelines for HBV screening, treatment, and prevention. The purpose of this clinical cohort study is to characterize the clinical features of chronic HBV infection at UTH and describe treatment and care outcomes. The investigators will enroll 500 adults and follow the cohort for up to 5 years to assess short and long-term viral, serologic, and liver outcomes such as cirrhosis and liver cancer.
