Quick Answer
Hepatitis C genotype 3 is a specific strain of the hepatitis C virus (HCV), identified by genetic testing. It is one of several genotypes (numbered 1 through 6) and is more common in South Asia and among people who inject drugs. Genotype influences treatment duration and medication choice, as genotype 3 has been historically harder to cure with older therapies.
- Hepatitis C genotypes are numbered 1 through 6, with subtypes like 3a and 3b.
- Genotype 3 is the second most common HCV genotype worldwide.
- Genotype 3 is associated with faster liver fibrosis progression than other genotypes.
- Determining genotype requires a blood test called HCV genotyping.
- Direct-acting antiviral treatments are effective for genotype 3, though some require longer therapy.
- Hepatitis C is a blood-borne virus, distinct from hepatitis A and B.

Hepatitis C is a liver infection caused by the hepatitis C virus (HCV), which spreads through blood-to-blood contact. Unlike hepatitis A (fecal-oral transmission) and hepatitis B (blood and sexual contact), HCV is primarily transmitted via shared needles, unsterile medical equipment, or blood transfusions before screening. Once a person is diagnosed with HCV, doctors determine the virus's genotype — a genetic variation that affects treatment response. Genotype 3 is one of the six major HCV genotypes and requires specific treatment considerations. Understanding your genotype helps tailor therapy for the best chance of cure.
