Steve Sternberg USA TODAY American-style SARS appears be a weaker cousin of the devastating pneumonia-like illness that has taken root in Canada and Asia, statistics out Thursday suggest. Severe acute respiratory syndrome, or SARS, is so much milder in the USA than abroad that Florida epidemiologist Steven Wiersma says some experts cautiously joke about renaming the U.S. version ''MARS,'' for mild acute respiratory syndrome. ''The cases we have seen in Florida have been of mild acute respiratory syndrome,'' Wiersma says. The latest Centers for Disease Control and Prevention (news - web sites) statistics reflect this. Of 166 people with suspected SARS in the USA, most have had normal chest X-rays. Only 33 have developed pneumonia or respiratory distress. Only four of 60 patients who needed hospitalization were still admitted Wednesday. Only one person has needed mechanical assistance breathing, and no one has died, says Julie Gerberding, director of the CDC. Canada, in contrast, reports 253 suspected cases and 10 deaths. Worldwide, 111 of the 2,781 SARS victims have died. Hundreds have developed pneumonia, and people in need of mechanical ventilation have filled intensive-care units in Hong Kong and Hanoi. Health authorities are baffled at the apparent difference in the severity of a disease caused by the same virus in different countries. ''We can't explain it,'' says John Jernigan, the CDC expert who is monitoring patient care in the USA. ''We're actively investigating possible reasons for that.'' One possible explanation is that the case definition used in the United States is extremely broad, linking a temperature and flu-like symptoms with foreign travel in affected areas. ''It's quite possible that people can meet the case definition for SARS and not be related to the outbreak at all,'' Jernigan says. Another, he says, is that the broad definition, coupled with efforts to educate travelers who may have been exposed to SARS abroad, may prompt people to get treatment earlier than elsewhere. In other developments: * The CDC has developed an educational video about SARS to be shown on international flights, Gerberding says. * Singapore's government said it would quarantine new workers from SARS-afflicted regions for 10 days. People who are quarantined will be monitored with Web cameras and an electronic wristband that sounds an alarm if they leave home.
