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.
Hepatitis Delta (HDV) is one of several infections that can cause damage to the liver. (Others include hepatitis A, B, C). HDV harms liver cells causing inflammation (swelling).
HCV/HIV coinfection means that a person has both viruses at the same time. For every 100 people with HIV, approximately 21 of them also have HCV.
