Hundreds of millions of people worldwide are affected by viral hepatitis. Chronic hepatitis B and C are estimated to affect half a billion of people. Many more are affected by acute hepatitis, especially in developing countries, resulting in significant symptoms, including death. Recently, clusters of cases of non A-E viral hepatis have raised concerns, and a potential link with adeno (and adeno-associated) viruses is being explored. The GVN is pursuing its mission of connecting and supporting scientists worldwide in their research on viral causes of human diseases, including viral hepatitis. On World Hepatitis Day, the GVN community stands with the many people affected by the disease, with a determination to find effective cures and vaccinations for all forms of viral hepatitis.
