• SARS is a contagious respiratory disease first identified in 2002.



• SARS is caused by a coronavirus (SARS-CoV) that exists in bats and civets in Southern China.



• The infection is spread easily from person to person through respiratory droplets.



• Infected people have symptoms of pneumonia, including fever and shortness of breath. Diarrhea may also occur.



• Severely affected people experience respiratory failure and may need mechanical ventilation. Older people, pregnant women, and those with underlying illnesses are at higher risk for severe disease.



• No cases of SARS have been diagnosed since 2004. SARS should be suspected in people with a compatible illness who work with SARS-CoV in the laboratory or who have gotten ill after exposure to bats or civets in Southern China.



• If there are grounds for suspicion, respiratory secretions are sent for testing to reference laboratories or to the CDC.



• There is no medication that is known to treat SARS. Treatment is supportive.



• During the 2002 outbreak, approximately 25% of people had severe respiratory failure and 10% died.



• The SARS outbreak in 2002 was controlled solely by using public-health measures such as wearing surgical masks, washing hands well, and isolating infected patients.
