Hepatitis A virus (HAV) usually goes away on its own in almost all cases with no serious complications. However, HAV may cause some patients to suffer liver failure.
About 95% of adults who are exposed to Hepatitis B virus (HBV) fully recover within 6 months (acute) without medication. About 5% have it all their lives (chronic) unless they are successfully treated.
Hepatitis C is a virus that affects the liver. It is the leading cause of liver failure and end stage liver disease and is a major cause of liver transplants in the United States.
