acute hepatitis B

Acute hepatitis B is a short-term infection caused by the hepatitis B virus, which affects the liver. It spreads through contact with infected blood, semen, or bodily fluids, commonly through unprotected sex, sharing needles, or from mother to child during childbirth. Many people experience symptoms like fatigue, fever, nausea, jaundice (yellowing of the skin and eyes), and dark urine. Most adults recover fully within a few months, though some may develop severe complications. Vaccination can prevent infection, and treatment focuses on relieving symptoms and supporting liver health during recovery.
