| Severe Acute
Respiratory Syndrome (SARS) |
Objective 1: Downgrade
or remove travel notifications as appropriate.
Activities
- CDC
will downgrade a travel
health warning to a travel health precaution when there
is:
- Adequate
and regularly updated reporting of surveillance data from the
area
- No evidence of ongoing transmission outside defined settings for for 20 days (two incubation periods) after date of onset of symptoms for the last confirmed case without an epidemiologic link, as reported by public health authorities.
- CDC
will remove a health precaution when there is:
- Adequate and regularly updated reporting of surveillance data from the area
- No
evidence of new cases for 30 days (three incubation periods) after
the date of onset of symptoms for the last case, as reported by
public health authorities.
- Limited
or no recent instances of exported cases from the area. An exported case is
an ill person who meets the definition for a probable or confirmed
case of SARS-CoV disease and who acquired SARS-CoV infection in
the area in question and then traveled outside the affected area
to another region and was diagnosed there (i.e., the person was
not identified as a part of contact tracing activities, and travel
was not restricted). This criterion excludes intentional or planned evacuations.
Objective 2: Reduce measures used for inbound travelers
as appropriate.
Activities
For
all passengers arriving from areas with SARS-CoV transmission:
- Continue
general education for passengers from a particular area until
the
travel health precaution
has been lifted (30 days after the onset of
symptoms for the last case in that area). Because travel patterns
may make it difficult to determine passengers' points of origin,
it may be more practical to continue general education until
travel health precautions
have been lifted for all areas.
- Continue
evaluating travelers who report symptoms of SARS during travel
until the
travel health precaution for that area has been lifted (30 days
after the onset of symptoms for the last case from that area).
For
passengers arriving from areas under a travel health warning:
- Continue
the use of screening questionnaires until the area of origin
is downgraded from
a travel health warning to a travel health precaution.
- Continue
meeting conveyances from SARS-affected areas and visually inspecting
passengers until the area of origin is downgraded from a travel health warning to a travel health precaution.
Objective 3 : Reduce other measures
used for outbound travelers as appropriate.
Activities
- Continue
pre-departure fever and symptom screening for passengers
departing from areas with ongoing unlinked transmission, but consider
discontinuing these activities 20 days after the onset of symptoms
for the last unlinked case.
- Continue
stop lists until there are no longer any cases under isolation
or contacts under quarantine.
Objective
4 : Reduce measures for management of passengers
with SARS-CoV disease
on conveyances as appropriate.
Activities
- Continue
meeting any flight with an ill passenger on board who has SARS-like
symptoms. If the passenger is seriously ill, evaluate and follow-up
according to established protocols.
- Continue
to collect locating information as long as the passenger has
symptoms compatible with SARS-CoV disease and has traveled from
an area with ongoing unlinked transmission (under a travel advisory).
For areas that have been downgraded to a travel health precaution, locating
information may not be needed unless the ill passenger meets
the epidemiologic criteria for likely exposure to SARS-CoV (See
Supplement B, Appendix B1).
- The
need for monitoring and quarantine of contacts of a passenger
from an area on travel health precaution should be determined after the ill
passenger has been fully evaluated.
