Severe acute respiratory syndrome


SARS appeared in 2002 in China. It spread worldwide within a few months, though it was quickly contained. SARS is a virus transmitted through droplets that enter the air when someone with the disease coughs, sneezes, or talks. No known transmission has occurred since 2004.


Fever, dry cough, headache, muscle aches and breathing difficulty are symptoms.


No treatment exists except supportive care.
