     92=== Classifications === 
     93 
     94The 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: 
     95 
     96* 1a, 1b, 1c 
     97* 2a, 2b, 2c 
     98* 3a, 3b 
     99* 4a, 4b, 4c, 4d, 4e 
     100* 5a 
     101* 6a 
     102* 7a, 7b 
     103* 8a, 8b 
     104* 9a 
     105* 10a 
     106* 11a 
     107 
     108=== Genotype patterns === 
     109 
     110It 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: 
     111 
     112* 1a - mostly found in North & South America; also common in Australia 1b - mostly found in Europe and Asia. 
     113* 2a - is the most common genotype 2 in Japan and China. 
     114* 2b - is the most common genotype 2 in the U.S. and Northern Europe. 
     115* 2c - the most common genotype 2 in Western and Southern Europe. 
     116* 3a - highly prevalent here in Australia (40% of cases) and South Asia. 
     117* 4a - highly prevalent in Egypt 
     118* 4c - highly prevalent in Central Africa 
     119* 5a - highly prevalent only in South Africa 
     120* 6a - restricted to Hong Kong, Macau and Vietnam 
     121* 7a and 7b - common in Thailand 
     122* 8a, 8b & 9a - prevalent in Vietnam 
     123* 10a & 11a - found in Indonesia 
     124 
     125=== HICDEP Conventions === 
     126 
     127Indicate only the genotype (numbers from 1-11) if the subtype is unknown. 
     128 
     129Combinations of geno- and subtypes: Use the "/" to separate (e.g. "4c/4d" or 
     130"1a/1b")
