WHO Health Topics: Measles
WHO " Measles is a highly contagious, serious disease caused by a virus. In 1980, before widespread vaccination, measles caused an estimated 2.6 million deaths each year. It remains one of the leading causes of death among young children globally, despite the availability of a safe and effective vaccine. Approximately 158 000 people died from measles in 2011 – mostly children under the age of five."
