Management
of Severe Acute Respiratory Syndrome (SARS)
These guidelines are constantly reviewed and updated as
new information becomes available. They are compiled to provide a generic
basis on which national health authorities may wish to develop guidelines
applicable to their own particular circumstance.
Revised
11 April 2003
Please
refer to Case Definitions for Surveillance of Severe Acute Respiratory
Syndrome (SARS)
Management
of Suspect and Probable SARS Cases
Hospitalize
under isolation or cohort with other suspect or probable SARS cases (see
Hospital Infection Control Guidance )
Take samples (sputum, blood, sera, urine,) to exclude standard causes
of pneumonia (including atypical causes); consider possibility of coinfection
with SARS and take appropriate chest radiographs.
Take samples to aid clinical diagnosis SARS including:
White blood cell count, platelet count, creatine phosphokinase, liver
function tests, urea and electrolytes, C reactive protein and paired sera.
(Pair sera will be invaluable in the understanding of SARS even if the
patient is later not considered a SARS case)
At the time of admission the use of antibiotics for the treatment of community-acquired
pneumonia with atypical cover is recommended
Pay particular attention to therapies/interventions which may cause aerolization
such as the use of nebulisers with a bronchodilator, chest physiotherapy,
bronchoscopy, gastroscopy, any procedure/intervention which may disrupt
the respiratory tract. Take the appropriate precautions (isolation facility,
gloves, goggles, mask, gown, etc. ) if you feel that patients require
the intervention/therapy.
In SARS, numerous antibiotic therapies have been tried with no clear effect.
Ribavirin with or without use of steroids has been used in an increasing
number of patients. But, in the absence of clinical indicators, its effectiveness
has not been proven. It has been proposed that a coordinated multicentred
approach to establishing the effectiveness of ribavirin therapy and other
proposed interventions be examined.
Definition of a SARS Contact
A
contact is a person who may be at greater risk of developing SARS because
of exposure to a suspect or probable case of SARS. Information to date
suggests that risky exposures include having cared for, lived with, or
having had direct contact with the respiratory secretions, body fluids
and/or excretion (e.g. faeces) of a suspect or probable cases of SARS.
Management
of Contacts of Probable SARS Cases
Give
information on clinical picture, transmission, etc. of SARS to the contact
Place under active surveillance for 10 days and recommend voluntary home
isolation
Ensure contact is visited or telephoned daily by a member of the public
health care team
Record temperature daily
If the contact develops disease symptoms, the contact should be investigated
locally at an appropriate health care facility
The most consistent first symptom that is likely to appear is fever
Management of Contacts of Suspect SARS Cases
As
a minimum the following follow up is recommended:
Give
information on clinical picture, transmission etc of SARS to the contact
Place under passive surveillance for 10 days
If the contact develops any symptoms, the contact should self report via
the telephone to the public health authority
Contact is free to continue with usual activities
The most consistent first symptom which is likely to appear is fever
Most national health authorities may wish to consider risk assessment
on an individual basis and supplement the guidelines for the management
of contacts of suspected SARS cases accordingly.
Removal
from Follow up
If
as a result of investigations, suspected or probable cases of SARS are
discarded (no longer meet suspect or probable case definitions) then contacts
can be discharged from follow up.
