Hepatitis B infection is caused by hepatitis B virus (HBV).The virus can cause acute hepatitis. Fewer than 5% of infected children under 5 years of age and 30-60% of infected adults are symptomatic. Common presentations include fever, loss of appetite, nausea, vomiting, abdominal pain, yellow coloring of the eyes, dark urine and clay colored or light stools. Symptomatic or not, approximately 5-10% of adults and 95% of perinatally infected infants are unable to clear the virus, thus becoming chronic carriers. They may subsequently develop chronic hepatitis, permanent liver damage or liver cancer.
