A
new disease called SARS
Severe acute respiratory syndrome (SARS) is a respiratory illness that has
recently been reported in Asia, North America, and Europe. This fact sheet
provides basic information about the disease and what is being done to
combat its spread. To find out more about SARS, go to www.cdc.gov/ncidod/sars/
and www.who.int/csr/sars/en/
. The Web sites are updated daily.
Symptoms
of SARS
In general, SARS begins with a fever greater than 100.4°F [>38.0°C].
Other symptoms may include headache, an overall feeling of discomfort, and
body aches. Some people also experience mild respiratory symptoms. After 2
to 7 days, SARS patients may develop a dry cough and have trouble
breathing.
How
SARS spreads
The primary way that SARS appears to spread is by close person-to-person
contact. Most cases of SARS have involved people who cared for or lived
with someone with SARS, or had direct contact with infectious material
(for example, respiratory secretions) from a person who has SARS.
Potential ways in which SARS can be spread include touching the skin of
other people or objects that are contaminated with infectious droplets and
then touching your eye(s), nose, or mouth. This can happen when someone
who is sick with SARS coughs or sneezes droplets onto themselves, other
people, or nearby surfaces. It also is possible that SARS can be spread
more broadly through the air or by other ways that are currently not
known.
Who
is at risk for SARS
Most of the U.S. cases of SARS have occurred among travelers returning to
the United States from other parts of the world with SARS. There have been
very few cases as a result of spread to close contacts such as family
members and health care workers. Currently, there is no evidence that SARS
is spreading more widely in the community in the United States.
Possible
cause of SARS
Scientists at CDC and other laboratories have detected a previously
unrecognized coronavirus in patients with SARS. The new coronavirus is the
leading hypothesis for the cause of SARS.
What
CDC is doing about SARS
CDC is working closely with the World Health Organization (WHO) and other
partners in a global effort to address the SARS outbreak. For its part,
CDC has taken the following actions:
- Activated
its Emergency Operations Center to provide round-the-clock
coordination and response.
- Committed
more than 700 medical experts and support staff to work on the SARS
response.
- Deployed
medical officers, epidemiologists, and other specialists to assist
with on-site investigations around the world.
- Provided
ongoing assistance to state and local health departments in
investigating possible cases of SARS in the United States.
- Conducted
extensive laboratory testing of clinical specimens from SARS patients
to identify the cause of the disease.
- Initiated
a system for distributing health alert notices to travelers who may
have been exposed to cases of SARS.
CDC
RECOMMENDATIONS
CDC has issued recommendations and guidelines for people who may be
affected by this outbreak.
For
individuals considering travel to areas with SARS:
CDC has issued two types of notices to travelers: advisories and alerts. A
travel advisory recommends that nonessential
travel be deferred; a travel alert does not
advise against travel, but informs travelers of a health concern and
provides advice about specific precautions. CDC updates information on its
website on the travel status of other areas
with SARS as the situation evolves.
For
individuals who must travel to an area with SARS:
CDC advises that travelers in an area with SARS should wash their hands
frequently to protect against SARS infection. In addition, CDC advises
that travelers may wish to avoid close contact with large numbers of
people as much as possible to minimize the possibility of infection. CDC
does not recommend the routine use of masks or other personal protective
equipment while in public areas. For more information, read the Interim
Guidelines about Severe Acute Respiratory Syndrome (SARS) for Persons
Traveling to Areas with SARS.
For
individuals who think they might have SARS:
People with symptoms of SARS (fever greater than 100.4°F [>38.0°C]
accompanied by a cough and/or difficulty breathing) should consult a
health-care provider. To help the health-care provider make a diagnosis,
tell them about any recent travel to places where SARS has been reported
or whether there was contact with someone who had these symptoms.
For
family members caring for someone with SARS:
CDC has developed interim
infection control recommendations for patients with suspected SARS in the
household. These basic precautions should be followed for 10 days
after respiratory symptoms and fever are gone. During that time, SARS
patients are asked to limit interactions outside the home (not go to work,
school, or other public areas).
For
health-care workers:
Transmission of SARS to health-care workers appears to have occurred after
close contact with sick people before recommended infection control
precautions were put into use. CDC has issued interim
infection control recommendations for health-care settings as well as
for the management
of exposures to SARS in health-care and other institutional settings.

CDC
protects people's health and safety by preventing and controlling
diseases and injuries; enhances health decisions by providing credible
information on critical health issues; and promotes healthy living
through strong partnerships with local, national, and international
organizations.
