Analysis of genetic heterogeneity of HCV NS3 and NS5b subgenomic regions from genotype 3a variants obtained from Pakistan.
•
Analyses showed that Pakistani isolates were as genetically diverse as global variants, with extensive intermixing.
•
Bayesian estimates showed that tMRCA for genotype 3a in Pakistan was last extant in ∼1896–1914 C.E.
•
Death/birth models suggest that HCV 3a reached saturating diversity with decreasing turnover rate and positive extinction.
