Hepatitis C virus (HCV) is a leading worldwide cause of
liver disease. Here, we use a new model of HCV spread to investigate the epidemic behavior of the virus and to estimate its basic
reproductive number from gene sequence data. We find significant
differences in epidemic behavior among HCV subtypes and suggest that
these differences are largely the result of subtype-specific
transmission patterns. Our model builds a bridge between the
disciplines of population genetics and mathematical epidemiology by
using pathogen gene sequences to infer the population dynamic history
of an infectious disease.
