An atypical form of pneumonia. It first appeared in November 2002 in the Guangdong Province of the People's Republic of China. SARS is now known to be caused by the SARS coronavirus (SARS-CoV), a novel coronavirus. SARS has a mortality rate of around 10 percent.

Initial symptoms are flu-like and may include: fever, myalgia, lethargy, gastrointestinal symptoms, cough, sore throat and other non-specific symptoms. The only symptom that is common to all patients appears to be a fever above 38 °C (100.4 °F). Shortness of breath may occur later. Symptoms usually appear 2–10 days following exposure, but up to 13 days has been reported. In most cases symptoms appear within 2–3 days. About 10–20% of cases require mechanical ventilation.
