Hepatitis B infection, caused by the hepatitis B virus (HBV), is commonly transmitted via body fluids such as blood, semen, and vaginal secretions. [1] Consequently, sexual contact, accidental needle sticks or sharing of needles, blood transfusions, and organ transplantation are routes for HBV infection. Infected mothers can also pass the infection to their newborns during the delivery period. [1]
