Abstract
Severe acute respiratory syndrome, SARS, is an illness that has been recently reported in Asia, North America, Europe and Africa. SARS appears to be a new disease. The first known case of atypical pneumonia occurred on 16 November 2002 in Foshan City, Guangdong Province, China. However, its significance was not known until later. The disease soon spread to the rest of the Guangdong Province and then further points in South East Asia. The World Health Organization (WHO) started to track the disease actively during mid-February 2003.
