What are the symptoms and signs of severe acute respiratory syndrome (sars)?

Unusual presentation: The prodrome is often somewhat prolonged, lasting for three to seven days and is characterized by fever (temperature ≥100.5ºf [>38ºc]) malaise, headache, and myalgias. Unlike many all other resp viral prodromes, most patients have no upper resp symptoms during this stage. At the end of this prodrome, the respiratory phase begins with a nonproductive cough, and may lead to dyspnea and resp failure.

SARS: Fever over 100.4 °f, dry cough, shortness of breath, headache, muscle stiffness, loss of appetite, malaise, mental confusion, rash and diarrhea have all been reported as part of this illness.
