Core Tip

Core tip: Geographic integration of hepatitis C virus (HCV) is a newly described epidemiological phenomenon that is illustrated for the first time in this review article. The global burden of HCV infection has surpassed expectations and HCV genotypes are no longer restricted to certain countries or regions. All countries and their citizens are at a higher risk of HCV infection. HCV integration can be either intra-continental or trans-continental. Globalization, immigration and drug trafficking, in addition to the traditional HCV transmission factors, have acted as vectors for the geographical integration of HCV. International efforts and new strategies that go beyond borders should be combined to tackle this global threat.
