Prevalence of Hepatitis C Virus Genotypes in a Mexican Population

Prevalence of hepatitis C virus in the Mexican population: A systematic review

“…In health personnel and the other asymptomatic subjects, the proportion of studies presenting prevalences 0.5% are 29% and 9%, respectively. Therefore the prevalence of these asymptomatic groups is probably higher than 0.37% calculated in Cital-Zamora et al 74 Another relevant article, which is part of the National Health Survey 2000 in Mexico, 51 explores a random population sample of 45,294 subjects from all Mexican states, of which 21,271 subjects were submitted to analysis of antibodies against HCV. This article, due to its methodology, has more representative data on HCV prevalence in Mexico and reports a value of 1.4%.…”

“…In one case, subtypes are not reported 73 and four studies determined that the most prevalent is subtype 1a 22,65,66,71 ; the other five studies reported that 1b is the most prevalent subtype. 6,37,69,72,74 Only one article shows substantially different results because it reports that genotype 2b is the most common subtype and even that genotypes 1a and 1b were not detected. 34 It is also important to note that in two papers, virus with genotype 2 is not reported.…”
