The recurrence of severe acute respiratory syndrome (SARS) in China
during 2004 has highlighted the continuing threat to human health from infectious
disease outbreaks. A zoonosis caused by a novel coronavirus,1,2 SARS
first emerged among humans in the southern Chinese province of Guangdong during
November 2002. By March 2003, SARS had spread to neighboring Hong Kong and
from there to Toronto, Ontario, and many other areas in a matter of days.
