the WHO's efforts, individual countries and local governments
also worked within their borders to control SARS. Since those
infected with the disease can infect others, many countries have
made attempts to prevent those exposed to SARS from spreading
it. In Canada, the provincial government in Ontario asked everyone
with even one of SARS's symptoms to stay home over the Easter
weekend. In Singapore, those suspected of being exposed to SARS
have been confined to their homes -- a measure that is sometimes
enforced with Web cams and electronic bracelets.
U.S. has not needed to institute these more stringent measures,
President Bush did sign an executive order on April 4 allowing
for a forced quarantine, if necessary, of those who might have
been exposed to SARS or a number of other diseases. The order
calls for the "apprehension, detention or conditional release
of individuals to prevent the introduction, transmission or spread
of suspected communicable diseases."
A few days
before that order was signed, Secretary of Health and Human Services
Tommy Thompson said that such measures didn't yet appear warranted
in the United States.
is a virus that is explosive ... and the only way to control it
is by quarantine, we have to consider it," he said. "But
we're not there yet."
governments are also working to prevent anyone already infected
with SARS from entering their country. Singapore is screening
all travelers arriving from areas the WHO designated as being
affected by SARS. Taiwan is taking the temperatures of all those
who arrive by air from China. The government in Hong Kong, one
of the areas hardest hit by the disease, has begun taking the
temperatures of airline passengers leaving the country to prevent
those who have the disease from flying.
In the U.S.,
air passengers arriving from affected regions are not screened
for SARS, but the Centers for Disease Control and Prevention is
giving them cards that explain the symptoms of the disease. The
U.S. is also advising that people planning nonessential trips
"to mainland China and Hong Kong; Singapore; and Hanoi, Vietnam
may wish to postpone their trips until further notice."
