Abstract

Hepatitis C virus (HCV) genotype (GT) distribution and frequency were studied among 22,407 unique specimens tested at a national reference testing laboratory. Subjects with HCV GT 3 were younger (P < 0.0001) than those with GT 1, 2, or 4, and the regional frequencies of HCV GT 2 and 3 ranged from 19.9% to 29.2%.

Frequencies of HCV genotypes (GT) 1, 2, 3, and 4 among 22,378 consecutive, unique clinical serum specimens, with results displayed according to regional locations of the submitting laboratories (A) and subject age groups (B). The nine geographic regions of the United States include the following: SA, South Atlantic (Delaware, District of Columbia, Florida, Georgia, Maryland, North Carolina, South Carolina, Virginia, West Virginia); WSC, West South Central (Arkansas, Louisiana, Oklahoma, Texas); ENC, East North Central (Illinois, Indiana, Michigan, Ohio, Wisconsin); ESC, East South Central (Alabama, Kentucky, Mississippi, Tennessee); MA, Mid-Atlantic (New Jersey, New York, Pennsylvania); P, Pacific (Alaska, California, Hawaii, Oregon, Washington); NE, New England (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, Vermont); WNC, West North Central (Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, South Dakota); and M, Mountain (Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, Wyoming).
