*Unless indicated otherwise.
†According to estimated prevalence of HBV infection and HCV infection in the source country based on clinical practice guidelines for immigrants and refugees in Canada.10,24 HBV infection: low risk < 2%, medium risk 2% to < 8%, high risk ≥ 8%; HCV infection: low risk < 3%, medium risk 3% to 5%, high risk > 5%; primary liver cancer: high risk = high risk for HBV or HCV infection.
