Surveillance Case Definition: Severe Acute Respiratory
Syndrome (SARS)
Confirmed Case –
A person with:
Early clinical presentation of SARS, i.e.:
Fever (over 38ºC) AND cough or breathing difficulty
AND Radiographic evidence consistent with SARS, Radiographic evidence of
infiltrates consistent with pneumonia or respiratory distress syndrome (RDS)
AND Laboratory evidence of SARS-associated coronavirus (SARS-CoV)
infection, i.e. Nucleic acid amplification test (e.g., PCR) positive
results or seroconversion or virus isolation.
OR
A deceased person with:
A history of early clinical presentation of SARS, i.e.: Fever AND cough
or difficulty breathing resulting in death.
AND Autopsy findings consistent with SARS, i.e.: Evidence of pneumonia
or RDS without an alternate identifiable cause.
AND Laboratory evidence of SARS coronavirus infection, i.e.: Nucleic
acid amplification test (e.g., PCR) positive results, or seroconversion
if appropriate specimens are available or virus isolation.
Probable Case -
A person with:
Early clinical presentation of SARS, i.e.: Fever over 38ºC AND cough or
breathing difficulty
AND
evidence consistent with SARS,
Radiographic evidence of infiltrates consistent with pneumonia or
respiratory distress syndrome (RDS)
AND Epidemiologically linked to a person or place linked to SARS, i.e.
Close contact** with a confirmed SARS case, within 10 days of onset of
symptoms.
OR Close contact with a symptomatic person who has laboratory evidence
of SARS-CoV infection, within 10 days of onset of symptoms.
OR Residence, recent travel or visit to an “Areas with recent local
transmission of SARS” within the 10 days prior to onset of symptoms.
OR
A decreased person with:
A history of early clinical presentation of SARS, i.e. Fever AND cough
or difficulty breathing resulting in death.
AND Autopsy findings consistent with SARS, i.e. Consistent with the
pathology of RDS without an identifiable cause.
AND Epidemiologically linked to a person or place linked to SARS, i.e.
Close contact with a confirmed SARS case, within 10 days of onset of
symptoms.
OR Close contact with a symptomatic person who has laboratory evidence
of SARS-CoV infection, within 10 days of onset of symptoms.
OR Residence, recent ravel or visit to an “Area with recent local
transmission of SARS” within the 10 days prior to onset of symptoms OR
close contact (including health care providers) with a probable case who
has been to an “Area with recent local transmission of SARS” within the
10 days prior to onset of symptoms
OR Symptomatic lab workers dealing with SARS CoV
OR
A deceased person with:
A history of early clinical presentation of SARS, i.e. Fever AND cough
or difficulty breathing resulting in death
AND Laboratory evidence of SARS coronavirus infection, i.e. Nucleic acid
amplification test (e.g., PCR) positive results, or seroconversion if
appropriate specimens are available or virus isolation.
NOTE:
**Close contact means having cared for, lived with or had face-to-face
(within 1 metre) contact with, or having had direct contact with
respiratory secretions and/or body fluids of a person with SARS. |
