Hepatitis B is a contagious liver disease that is caused by the hepatitis B virus (HBV). The severity of the disease ranges from a mild illness lasting a few weeks (acute) or a lifelong illness (chronic). Although a majority of adults develop symptoms from acute Hepatitis B virus infection, many young children do not. Adults and children over the age of 5 years are more likely to have symptoms. Symptoms of acute Hepatitis B can include: fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine, clay-colored bowel movements, joint pain, and jaundice (yellow color in the skin or the eyes). Symptoms of chronic hepatitis B can be similar to acute Hepatitis B, but most individuals with chronic Hepatitis B may remain symptom-free for as long as 20 or 30 years. 

Hepatitis B vaccine is the most effective way to prevent infection. The routine vaccination series consists of 3 shots administered over a 6-month period at 0, 1-2 months, and 6-18 months. The vaccine is also recommended for infants soon after birth or before hospital discharge.
