问武汉肺炎为时过早，问非典可作为借鉴

Impact of SARS Epidemic

The 2003 epidemic was responsible for more than 8,000 cases of SARS in 29 countries, including 29 cases in the United States. There were 774 SARS-related deaths; none reported in the U.S. SARS was fatal for 1 in 10 patients. Age was an important factor in mortality; the risk of the disease being fatal increased to about half of patients over the age of 60. A small percentage of patients had long-term effects from their illness, including depression or anxiety, cough, shortness of breath, chronic lung disease or kidney disease. However, most patients fully recovered.
