The condition and the treatment
Hepatitis C is a disease of the liver that is caused by the hepatitis C virus. There are 6 different types (genotypes) of the virus. Some people who are infected with the hepatitis C virus get rid of it quickly without treatment but most people develop a long‑lasting infection; this is called chronic hepatitis C. People who have chronic hepatitis C may feel well for many years, but the virus causes damage to their liver later and can make them feel ill.
Ombitasvir–paritaprevir–ritonavir (Viekirax) and dasabuvir (Exviera) are drugs used to treat genotypes 1 and 4 of the hepatitis C virus. They are sometimes taken with another drug, called ribavirin, and can get rid of the virus in people who have never had treatment or who had treatment before that didn't get rid of the virus.
