What are the treatments for severe acute respiratory syndrome (SARS)?

There is no proven effective treatment for SARS. The CDC recommends that health-care professionals treat SARS patients in the same way they would treat someone with an unknown type of pneumonia. There have been different treatment

approaches used throughout the affected countries, and the CDC is in constant communication with officials and health-care workers there.

In spite of a concerted global effort, scientists have yet to find an effective treatment for SARS. Suspected cases of SARS must be isolated, preferably in negative pressure rooms, with full barrier nursing precautions taken for any necessary contact with these patients. Doctors may try treating SARS with antiviral drugs, including oseltamivir and ribavirin, and corticosteroids. However, there is no evidence that these or any other drugs are effective. The virus eventually disappears. People with mild symptoms need no specific treatment. Those with moderate difficulty breathing may need to receive oxygen by plastic nasal prongs or a face mask. Those with severe difficulty breathing may need mechanical ventilation to aid breathing. Research now is focused on developing a test for rapid diagnosis, effective therapies, and a preventive vaccine.

There may be some benefit from using steroids and other immune system modulating agents in the treatment of the more acute SARS patients as there is some evidence that part of the more serious damage SARS causes is also due to the body's own immune system overreacting to the virus. Research is continuing in this area. A combination of antiviral drugs commonly used to treat AIDS - lopinavir/ritonavir along with ribavirin - has been shown in clinical studies to prevent serious complications and deaths from SARS. Further testing is needed before these drugs are approved for use in people with SARS.

What are the symptoms and signs of SARS? - The main symptoms of SARS are high fever, combined with a dry cough, shortness of breath, or breathing difficulties.
How is SARS diagnosed? - Blood is tested for SARS infection when the illness is first recognized and again 3 weeks later. Three possible diagnostic tests have emerged.
