What are the different types of hepatitis C (HCV)?

There are two types of hepatitis C infection, acute (short-lived) and chronic (long-lived). Acute hepatitis C symptoms can last from a few weeks to six months. Most symptoms of acute hepatitis are mild. It's possible to have acute or chronic hepatitis without feeling ill or having any symptoms. Chronic hepatitis C is more severe and more common than its acute form. Blood tests are used to determine the type and level of hepatitis C infection. Your doctor should monitor your liver for progressive damage. There are also at least six types of the hepatitis C virus, called genotypes. Chronic hepatitis C treatment depends on the genotype of the virus a person has, and other factors.
