18 June 2014 -- Viral hepatitis – a group of infectious diseases known as hepatitis A, B, C, D, and E – affects millions of people worldwide, causing acute and chronic liver disease and killing close to 1.4 million people every year. Hepatitis remains largely ignored or unknown. In April this year, WHO issued new recommendations on treatment of hepatitis C. In May, World Health Assembly delegates from 194 Member States adopted a resolution to improve prevention, diagnosis, and treatment of viral hepatitis. On World Hepatitis Day, 28 July 2014, WHO and partners urge policy-makers, health workers and the public to "think again" about this silent killer.
