Scientists have identified between 6 and 11 distinct HCV genotypes. The different HCV genotypes and subtypes have different distributions throughout the world.
Genotypes 1, 2, and 3 are found worldwide. Genotype 4 occurs in the Middle East, Egypt, and central Africa. Genotype 5 is present almost exclusively in South Africa. Genotype 6 is seen in Southeast Asia.
Genotype 1 is the most common HCV genotype in the United States. It’s found in nearly 75 percent of all HCV infections in the country. Most of the remaining people in the United States with HCV infection carry genotypes 2 or 3.
The HCV genotype isn’t absolutely related to the rate of liver damage or the likelihood of eventually developing cirrhosis. However, genotype is a predictor of the outcome of treatment.
Genotype 1 was considered the most problematic as the cure rates were very low. With the arrival of the direct acting antivirals, the cure rates have risen to over 90%. Right now genotype 3 is the hardest to cure but there are new drugs coming that will change that.
There are at least 6 genotypes -- genetic strains -- of hepatitis C virus. Knowing your hepatitis C genotype is an essential part of your treatment plan because the genotype will affect your treatment, such as how long you're treated.
All types can be treated and be cured. Below this is a link on how to treat each type. I'm not sure any Genotype is more serious then another, just treated different and some types are harder to cure. Best to you.

Genotype 6
This genotype is common in south China, Hong Kong and other southeast Asian countries
There are 6 types of hepatitis. All are serious. Some can be treated. Some can be cured. One 1 is Hepatitis C.
