Severe acute respiratory syndrome (SARS) is a viral respiratory disease caused by a SARS-associated coronavirus.

It was first identified at the end of February 2003 during an outbreak that emerged in China and spread to 4 other countries.

WHO co-ordinated the international investigation with the assistance of the Global Outbreak Alert and Response Network (GOARN) and worked closely with health authorities in affected countries to provide epidemiological, clinical and logistical support and to bring the outbreak under control.
