What Are the Hepatitis C Genotypes and Where Are They Found?
Today, approximately 2% of the world's population is infected with Hepatitis C. Like other viruses, hepatitis C has evolved into distinct subgroups, which has made the virus difficult to treat with a universal drug.
Doctors recognize six major genotypes, although there may be as many as 11. Because genotypes are the result of evolution, distinct types are often clustered in certain parts of the world and distributed elsewhere through migration. Genotypes 1, 2 and 3 are common in North America, but are also seen across the globe. Genotype 4 primarily exists in the Middle East, Egypt and Central Africa; genotype 5 is largely confined to South Africa and genotype 6 to Southeast Asia.
