Breakdown of Geno-type~worlwide

i knew about 1-3 & heard about a 6....was surprised to see G-11!

Genotype patterns

It is believed that theHhepatitis C virus has evolved over a period of several thousand years. This would explain the current general global patterns of genotypes and subtypes:

1a - mostly found in North & South America; also common in Australia
1b - mostly found in Europe and Asia.
2a - is the most common genotype 2 in Japan and China.
2b - is the most common genotype 2 in the U.S. and Northern Europe.
2c - the most common genotype 2 in Western and Southern Europe.
3a - highly prevalent here in Australia (40% of cases) and South Asia.
4a - highly prevalent in Egypt
4c - highly prevalent in Central Africa
5a - highly prevalent only in South Africa
6a - restricted to Hong Kong, Macau and Vietnam
7a and 7b - common in Thailand
8a, 8b & 9a - prevalent in Vietnam
10a & 11a - found in Indonesia

This was the old genotype numbering system.
All the Genotypes above 6 have been re classified into G1 thru G6

International standardization and coordination of the nomenclature of variants of hepatitis C virus (HCV) is increasingly needed as more is discovered about the scale of HCV-related liver disease and important biological and antigenic differences that exist between variants.

The table below comes from http://hcv.lanl.gov but is no longer at the link i have.
But you will get the idea. 5a is missing but G5 only has 5a.
Old designation...New designation
I.........................1a
II........................1b
III.......................2a
IV......................2b
V.......................3a
VI......................3b
4 alpha..............4n
4 beta................4o
7a.....................6e
7b.....................6d
7c/NGII/VII .........6f
7d.....................6c
NGI...................6n
8a.....................6l
8b.....................6k
9a.....................6h
9b.....................6i
9c.....................6j
10a/TD3............3k
11a...................6g

Thankyou!!!!

I was told years ago that I was type V (they called it '5' but wrote it 'V').   Then a doctor wrote down '1' in error, and when I pointed it out they did another test and told me I was 3a.    In the back of my mind I wondered whether I had multi-g's,  even though it had been confirmed I was a '3'.

You've both cleared up some of my excess baggage!!!!

3a - highly prevalent here in Australia (40% of cases) and South Asia.

I'll clear up this G3a is worldwide. Australia and some European countries in high numbers.

No Probs.
Its confusing ay.

Much less confusing now lol...  I contracted it in Aust (I always wondered about the V as hadn't heard of another '5').
