For purposes of case finding and surveillance in the United States, the March 17th CDC SARS case definition has been updated as follows:

• Temperature must be measured

• SARS areas are limited to those with suspected or documented community transmission; this differs from the WHO definition as it excludes areas where secondary transmission has been limited to only health care workers or direct household contacts. Note: the list of SARS areas will be updated as new information becomes available.

OR Close contact within 10 days of onset of symptoms with either a person with a respiratory illness and travel to a SARS area or a person under investigation or suspected of having SARS
