Mysterious Pneumonia Cases Still Growing
New Evidence Shows Virus Is Likely Cause of SARS Outbreak

Gerberding says severe acute respiratory syndrome appears to be transmitted only through close, personal contact with an affected individual, such as a family member or healthcare worker of an infected individual. There is no evidence to suggest that casual contact with someone with SARS can result in infection.
Symptoms of the pneumonia or the respiratory illness caused by SARS develop within two to seven days after exposure. A CDC health alert advises travelers to Southeast Asia to seek medical attention immediately if they become ill with a fever and respiratory symptoms, such as cough or difficulty breathing, within 10 days of travel to affected areas. A related travel advisory also states that U.S. citizens planning nonessential travel to the regions affected by the SARS outbreak may wish to postpone their trips until further notice.
At this time, officials say there is no reason to believe that this mysterious pneumonia might have unnatural causes or is an example of a bioterrorist attack. The pattern of pneumonia outbreak is what would normally be expected from a contagious respiratory or flu-like illness, but CDC officials say they are keeping an open mind about the issue.
