Hepatitis C Genotypes - Topic Overview
Six major strains (genotypes) of the hepatitis C virus (HCV) cause infection. You may be infected with more than one genotype at a time.Genotype 1 is the most common strain in the United States.Genotypes 1, 2, and 3 are found worldwide.Genotype 4 is found throughout northern Africa.Genotype 5 commonly is found in South Africa.Genotype 6 is common in Asia.Genotype testing is done with a blood test.How genotype affects treatmentAlthough genotype tests are not used to diagnose HCV infection, they may be done before treatment begins. Knowing the genotype may help a doctor choose the best treatment plan. You should know your genotype before treatment starts.Antiviral medicines are more likely to work for people who have genotype 2 or 3. If blood tests show that you have responded to antiviral therapy (the virus is not detected in your blood) after 6 months, treatment may be:Continued for another 6 months, if you are infected with genotype 1.Stopped, if you are infected with genotype 2 or

Hepatitis C: Your Risk for Cirrhosis - Topic Overview
Up to 85% of people who are infected with the hepatitis C virus will develop long-term (chronic) infection.1 About 25% of people who have chronic hepatitis C will go on to develop cirrhosis—severe liver damage and scarring—after a period of about 20 years or more.2Certain factors may affect how quickly problems such as cirrhosis or liver cancer develop.The way cirrhosis develops depends on:3How much liver damage you had when you were diagnosed and how long you have had the infection. The amount of liver damage you have compared with how long you have had hepatitis C can help determine how likely it is that you will develop cirrhosis.Your age when you were infected. People who are older than 40 when they become infected may develop cirrhosis more quickly. How much alcohol you drink. People who drink too much alcohol (heavy drinking) can develop cirrhosis much more quickly than people with who do not drink or who drink very little alcohol.Your gender. Men may develop cirrhosis more
