Recommended codes for HIV-1 subtypes
The nomenclature for CRFs is taken from the http://www.hiv.lanl.gov/content/sequence/HelpDocs/classification.html
It is recommended that cohorts check the coding of subtypes according to the list below prior to submission of the data.

Recommended codes for HCV geno- and subtypes
From http://www.hepatitis-central.com/hcv/genotype/explained.html
Classifications
The most commonly used classification of Hepatitis C virus has HCV divided into the following genotypes (main types): 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11. As we've highlighted, HCV genotypes can be broken down into sub-types, some of which include:
- 1a, 1b, 1c
- 2a, 2b, 2c
- 3a, 3b
- 4a, 4b, 4c, 4d, 4e
- 5a
- 6a
- 7a, 7b
- 8a, 8b
- 9a
- 10a
- 11a
Genotype patterns
It is believed that the hepatitis 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
HICDEP Conventions
Indicate only the genotype (numbers from 1-11) if the subtype is unknown.
Combinations of geno- and subtypes: Use the "/" to separate (e.g. "4c/4d" or "1a/1b") Combinations
