Symptoms

The hallmark symptoms are:

  • Cough
  • Difficulty breathing
  • Fever greater than 100.4 degrees F (38.0 degrees C)
  • Other breathing symptoms

The most common symptoms are:

  • Chills and shaking
  • Cough -- usually starts 2-3 days after other symptoms
  • Fever
  • Headache
  • Muscle aches

Less common symptoms include:

  • Cough that produces phlegm (sputum)
  • Diarrhea
  • Dizziness
  • Nausea and vomiting
  • Runny nose
  • Sore throat

In some people, the lung symptoms get worse during the second week of illness, even after the fever has stopped.


Signs and tests

Your health care provider may hear abnormal lung sounds while listening to your chest with a stethoscope. In most people with SARS, changes on a chest x-ray or chest CT show pneumonia, which is typical with SARS.




Tests used to diagnose SARS might include:

Tests used to quickly identify the virus that causes SARS include:

  • Antibody tests for SARS
  • Direct isolation of the SARS virus
  • Rapid polymerase chain reaction (PCR) test for SARS virus

All current tests have some limitations. They may not be able to easily identify a SARS case during the first week of the illness, when it is most important.
