Core Tip

Core tip: Hepatitis C virus (HCV) infection is a global public health burden, causing an increasing level of liver-related morbidity and mortality due to the disease progression. Unfortunately, in many countries, there is a lack of robust epidemiological data, especially HCV genotypes distribution, upon which to base country-specific prevention, diagnosis and treatment strategies in order to reduce the disease burden represented by HCV. Stratification by viral genotypes at national and regional level, and a better understanding of viral diversity within target populations, might also critically inform the rational design and testing of future HCV vaccines.
