Prevalence of HCV genotypes and subtypes in Southeast Asia: A systematic review and meta-analysis.

Known for its high genetic diversity and variation in genotypic presence in different regions of the world, hepatitis C virus (HCV) is estimated to infect about 71 million people globally. Selection of an appropriate therapeutic regimen largely depends on the identification of the genotype responsib...
