Diagnosis

When SARS first surfaced, no specific tests were available to help doctors diagnose the disease. Now several laboratory tests can help detect the virus. But no known transmission of SARS has occurred anywhere in the world since 2004.

Treatment

In spite of a concerted global effort, scientists have yet to find an effective treatment for SARS. Antibiotic drugs don't work against viruses, and antiviral drugs haven't shown much benefit.
