(HealthDayNews) -- Hepatitis is an inflammation of the liver that's caused by a virus, according to the U.S. Centers for Disease Control and Prevention.

The United States harbors three types, each caused by a different virus: hepatitis A, hepatitis B and hepatitis C. The symptoms are similar and can include fatigue, loss of appetite, nausea, abdominal discomfort, dark urine or yellowing of the skin and eyes (jaundice).

Hepatitis A -- Good personal hygiene and proper sanitation can help prevent this form. Vaccines are available for people ages 2 and older.

Hepatitis B -- This virus can cause lifelong infection, scarring of the liver, liver cancer, liver failure and death. A hepatitis B vaccine is available for all ages.

Hepatitis C -- You may be at risk for this viral infection if you received blood from a donor who tested positive, have injected illegal drugs, received a blood transfusion or solid organ transplant before July 1992, were a recipient of clotting factor(s) made before 1987, or have been on long-term kidney dialysis.
