SARS Symptoms and Signs

Symptoms of SARS can be similar to those of other viral infections. The first symptoms begin two to seven days after exposure and may include the following:

  • Fever (temperature of more than 100.4 F)
  • Headache
  • Fatigue (tiredness)
  • Muscle aches and pain
  • Malaise (a feeling of general discomfort)
  • Decreased appetite
  • Diarrhea

Respiratory symptoms develop three or more days after exposure. Respiratory symptoms include the following:

  • Dry cough
  • Shortness of breath
  • Runny nose and sore throat (uncommon)

By day seven to 10 of the illness, almost all patients with laboratory evidence of SARS infection had pneumonia that could be detected in the lungs on X-ray films. Respiratory distress may occur. This symptom is a concern for the patient and the doctors because it suggests the disease is becoming more severe.
