What are hepatitis C genotypes?

ANSWER

Scientists call the different types of hepatitis C “genotypes.” Each hepatitis C genotype has a different genetic makeup that helps define it. There are six basic genotypes. Scientists break down each of these numbers into subtypes by letters, like 1a, 1b, etc. Some genotypes are more common in certain parts of the world and respond better to a particular treatment.
