Are There Different Types of Hepatitis C Viruses?

Just as sisters are alike in some ways, but still different in others, there are different types of hepatitis C viruses called "genotypes."

Currently, scientists have found 6 major genotypes of the hepatitis C virus worldwide. Some of these genotypes can be broken into even smaller groups, called subtypes.

Of the people infected with the hepatitis C virus in the United States:

  • Approximately 75% have genotype 1
  • 20% to 25% have genotypes 2 or 3
  • The rest have genotypes 4, 5, and 6

Why is it good to know your type?

It’s important to know which genotype you have because not all treatments work for all types of chronic hepatitis C. Doctors use a person's genotype to help determine the type of treatment the person will receive.

How do you know your genotype?

Your doctor can do a blood test to find out your genotype. Get the conversation started with your doctor about hepatitis C, genotypes, and how to keep your liver healthy.
