Severe Acute Respiratory Syndrome (SARS)
Severe Acute Respiratory Syndrome (SARS) is caused by a previously unknown type of coronavirus. There may be factors related to the infected person's immune system or factors in the environment that affect the symptoms and severity of SARS. Normally, coronaviruses cause mild to moderate upper-respiratory symptoms, such as the common cold.
