People respond differently to treatment, depending on which of the Hepatitis C virus genotypes they have. About 40-50% in people with genotype 1 have a good, stable response with 8–48 weeks of treatment. In people with genotypes 2 and 3, about 70-80% have a good, stable response with 24 weeks of treatment. About 65% of people with genotype 4 have a good, stable response with 48 weeks of treatment. There is not much evidence about how well treatment works for people with genotype 6 disease is currently sparse. The evidence that does exist looks at results after 48 weeks of treatment at the same medication doses as people with genotype 1.
