Summary

  • Prevalence rates of HCV in very low endemicity countries vary greatly from those in highly endemic areas where rates of infection are as high as 10% (Figure 1)[CDC Travel]
  • Major factors that contribute to current and future HCV prevalence include new infections, population migration, and mortality and cure rates (Table 1)
  • Transmission routes vary geographically, with iatrogenic transmission remaining important in resource-constrained settings and parenteral transmission predominant in resource-rich settings
