Abstract excerpt

Occult Hepatitis B virus infection (OBI) is prevalent among high-risk and immunized populations in regions with high endemicity. OBI could be reactivated and/or transmitted, making it a significant risk factor for liver disease progression, including cirrhosis and hepatocellular carcinoma. This cross-sectional study was conducted on vaccinated children born to HBsAg positive mothers in the Esfandiar region of...
