Respiratory symptoms. In general, severe acute respiratory syndrome (sars), begins with a high fever (temp >100.4°f [>38.0°c]). Other symptoms may include headache, an overall feeling of discomfort, and body aches. Some people also have mild respiratory symptoms at the outset. About 10-20% of patients have diarrhea. After 2 to 7 days, sars patients may develop a dry cough. Most patients develop pneumonia.
Nonspecific. The symptoms are generally myalgias, fever, chills, cough, and confusion, which can be present in nearly any systemic viral infection, and can present as a severe case of influenza. Contact with an infected person or travel to an endemic area would be needed to raise suspicion of this disease in the US.
