Incubation Period and Symptoms

The incubation period is short, approx 3-6 days (maximum 10 days), and, despite the media frenzy surrounding the initial outbreak, SARS is less infectious than influenza. The following clinical case definition of SARS has been developed for public health purposes (82).

A person with a history of any combination of the following should be examined for SARS:

• One of more symptoms of lower respiratory tract illness (cough, difficulty in breathing, or dyspnea); and

• Radiographic evidence of lung infiltrates consistent with pneumonia or respiratory distress syndrome or postmortem findings of these with no identifiable cause;

• No alternative diagnosis can fully explain the illness.

Laboratory tests have been developed that include detection of viral RNA by PCR from nasopharyngeal secretions or stool samples, detection of antibodies by enzyme-linked immunosorbent assay or immunofluorescent antibody in the blood, and viral culture from clinical specimens.
