Q:
What is SARS?
A:
Severe acute respiratory syndrome (SARS) is
a highly contagious respiratory illness associated
with coronavirus that has recently been reported
in Asia, North America, and Europe. SARS is
an infection in which affected individuals develop
a fever, followed by respiratory symptoms such
as cough, shortness of breath or difficulty
breathing. In some cases, the respiratory symptoms
become increasingly severe, and people require
oxygen support and mechanical ventilation. Other
symptoms of SARS include muscle aches, headaches,
and sore throat. Currently,
the cause of SARS is unknown, and no specific
agents have been identified.
Q:
What is coronavirus?
A:
Normally, coronaviruses cause mild to moderate
upper-respiratory illness such as the common
cold. When viewed under a microscope, the coronavirus
has a halo or crown-like appearance. Coronaviruses
can also be found in animals.
Q:
What is metapneumovirus?
A:
Metapneumovirus is part of the paramyxovirus
family. Viruses in the paramyxo family can be
responsible for mumps, measles, pneumonia and
the common cold. The metapneumovirus was only
recently identified in humans and has been proven
to be very common. It causes respiratory symptoms
that are not usually as severe as those evidenced
in the current outbreak.
Q:
What are the symptoms of SARS?
A:
The main symptoms of SARS are high fever (
38?Celsius), dry cough, shortness of breath
or breathing difficulties. Changes in chest
X-rays indicative of pneumonia also occur. SARS
may be associated with other symptoms, including
headache, muscular stiffness, loss of appetite,
malaise, confusion, rash and diarrhoea.
Q:
How contagious is SARS?
A:
Based on currently available evidence, close
contact with an infected person is needed for
the infective agent to spread from one person
to another. Contact with aerosolized (exhaled)
droplets and bodily secretions from an infected
person appears to be important. To date, the
majority of cases have occurred in hospital
workers who have cared for SARS patients and
the close family members of these patients.
However, the amount of the infective agent needed
to cause an infection has not yet been determined.
Q:
How should SARS patients be managed?
A:
Patients should be placed in an isolation unit.
Strict respiratory and mucusol barrier nursing
is recommended. It is very important that suspected
cases are separated from other patients and
placed in their own hospital room. Health care
workers and visitors should wear efficient filter
masks, goggles, aprons, head covers, and gloves
when in close contact with the patient.

Q:
What is the treatment for SARS?
A:
While some medicines have been tried with some
success, no drug can, at this time, can cure
the disease. Antibiotics do not appear to be
effective. Symptoms should be treated by adequately
protected health professionals.
Q:
When will this disease be identified?
A:
An international multicenter research project
to expedite identification of the causative
agent was established on Monday 17 March. Eleven
top labs in ten countries are consulting daily
and are working together to identify the causative
agent. Various specimens have been collected
from cases and post-mortem examinations. Laboratory
tests are ongoing and a candidate causative
infectious agent is under investigation.
Q:
How fast does SARS spread?
A:
SARS appears to be less infectious than influenza.
The incubation period is short, estimated to
range from 2-7 days, with 3-5 days being more
common. However, the speed of international
travel creates a risk that cases can rapidly
spread around the world.
Q:
Does the drug Ribavirin cure SARS?
A:
Health Canada's Special Access Programme (SAP)
provides access to drugs that are not approved
for sale in Canada for patients suffering from
serious and life-threatening conditions when
other marketed therapies have either failed
or are unsuitable.
SAP
is currently providing access to intravenous
and oral Ribavirin for use in SARS. These products
are not approved for sale in Canada. The efficacy
of Ribavirin in treating SARS is unknown, although
it has been used to treat a variety of viral
illnesses including Respiratory Syncytial virus,
Lassa fever, and Hanta virus.
SAP
is working closely with health care professionals
at each of the hospitals involved to gather
information on the use of Ribavirin for SARS,
and potential adverse effects.
Q:
How is SARS diagnosed?
A:
In the absence of a laboratory test, doctors
are using the following criteria to diagnose
SARS:
people
who have recently travelled to affected countries
in Asia or who have had close contact with persons
diagnosed with SARS; and
develop
a fever (over 38.0 degrees Celsius); and
have
one or more of the following respiratory symptoms:
cough, shortness of breath or difficulty breathing.
Q:
What is the difference between classical/typical
pneumonia and atypical pneumonia?
A:
Classical/typical pneumonia is mainly caused
by bacteria such as streptococcus.
Atypical
pneumonia is mainly caused by viruses such as
influenza and adenovirus, bacteria such as chlamydia
and mycoplasma, and other unknown agents.
Q:
What is the difference between influenza and
atypical pneumonia?
A:
Influenza symptoms such as fever, cough and
headache usually subside within a few days without
any serious complications or signs of pneumonia.
Q:
Which countries have reported cases of SARS?
A:
Click here for SARS Locator.
Q:
What is the difference between a "suspect"
and a "probable" case?
A:
A "suspect" case of SARS is a person
who fits into one of the following two categories:
a
person who develops fever and one or more respiratory
symptoms, including cough, shortness of breath
or difficulty breathing, within 10 days of returning
from travel to areas in Asia where SARS cases
are being reported; or
a
person who develops fever and one or more respiratory
symptoms, including cough, shortness of breath
or difficulty breathing, within 10 days of having had close contact with a "probable"
case of SARS.
"Probable"
cases of SARS are similar to suspect cases,
but often they have a more severe illness, with
progressive shortness of breath and difficulty
breathing, and in some cases, chest x-rays show
signs of atypical pneumonia.
Q:
Who is at risk of developing SARS?
A:
At this time, the only risk factors identified
are recent travel to affected countries in Asia,
or close contact with a person who has SARS.
Close contact includes living in the same household,
providing health care to someone with SARS,
or having direct contact with respiratory secretions
and body fluids of a person with SARS.
Q:
Is there anything that can be done to help prevent
the spread of SARS?
A:
Practising good personal hygiene is a key to
stopping the spread of this disease. Thorough
hand-washing - using hot, soapy water and lathering
for at least 20 seconds - is the single most
important procedure for preventing infections.
This is because disease-causing micro-organisms
can frequently be found on the hands.
Q:
Is this disease spreading through or being spread
by the Asian community only?
A:
While identifying the cause of the disease has
been difficult, time has shown that its spread
is not limited to any one geographic region,
nor is it linked to a particular ethnic group.
SARS can be contracted and passed on by any
individual, regardless of their cultural identity
or background. The only requirement to becoming
infected is by direct, close contact with a
SARS affected individual.
Q:
Is there any evidence to suggest air-borne transmission?
A:
Based on available information, and the results
of scientific analysis, transmission is most
consistent with droplets and direct contact
with a patient's secretions.
Q:
Is it safe to use public swimming pools?
A:
There is no evidence of transmission through
swimming. In any case, people feeling unwell
should not go swimming.
Q:
Is there a vaccine against the disease?
A:
A vaccine is not yet available.
Q:
How can I avoid contracting the disease in an
office setting?
A:
If feeling unwell, employees should seek early
medical advice and not go to work. All staff
should maintain good personal hygiene and a
healthy lifestyle. The office should be well
ventilated, and windows opened from time to
time. Air conditioners should be well maintained
and cleaned regularly. Office furniture and
equipment should be kept clean.
Q:
How can I prevent contracting the disease in
a lift?
A:
Maintain good personal hygiene. Wash hands frequently.
Cover your nose and mouth with a tissue when
sneezing or coughing. Wear a face mask if you
have symptoms of a respiratory tract infection.
Building management should ensure lifts and
public access areas are kept clean - lift control
panels and door handles should be thoroughly
and frequently cleaned with disinfectant or
a diluted bleach.
Q:
Should I take any precautions when visiting
a health care facility?
A:
People seeking medical consultation should maintain
good personal hygiene. Wash hands frequently.
Wear a face mask.
Q:
What precautions should be adopted if a family
member or friend has contracted the disease?
A:
People should avoid visiting patients with atypical
pneumonia. People who have close contact with
patients suffering from the disease should:
-
Observe quarantine regulations. You will be
required to stop work, stay at home and report
daily to surveillance centres for 10 days.
-
If you must leave your home, wear a face mask
and observe good personal hygiene.
-
If you think you may have had contact with an
infected person, wear a face mask for at least
10 days and seek medical advice.
-
At home, clean toys and furniture properly (using
a solution of 1 part bleach : 49 parts water).
-
Pay special attention to your health and hygiene.
Wash hands frequently.
-
Seek early medical advice if feeling unwell.
Q:
Should clothes be washed after visiting hospitals?
A:
Yes. Wash them immediately you get home.
Q:
What is the Department of Health advice about
sharing food at home or in restaurants?
A:
Do not share eating utensils. Adopt the good
practice of using serving spoons and chopsticks.
Q:
Can the disease be prevented by wearing a face
mask?
A:
Wearing a proper face mask can help lower
the risk of infecting the disease. Make sure
hands are washed before putting on a mask.
Q:
Who should wear a face mask?
A:
The following people should wear a face mask:
-
People with respiratory infection symptoms
-
People who care for patients with respiratory
infection symptoms
-
People who have been in close contact with confirmed
cases of atypical pneumonia should wear a face
mask for at least 10 days from the last contact
-
Health care workers
-
When travelling to places with SARS cases
Q:
What type of face mask should be used?
A:
An ordinary surgical face mask is effective
in preventing the spread of droplet infections.
Q:
Is the N95 face mask the only effective model
to prevent atypical pneumonia?
A:
Surgical face masks and the N95 face mask are
both effective in preventing the spread of droplet
infections. Wear N95 face masks, which is recommended
by WHO for health care workers, if you are in
direct contact with people with SARS symptoms
and are travelling to places with severe SARS
outbreak like China and Hong Kong.
Q:
How often should a face mask be replaced?
A:
In general, a surgical face mask needs to be
changed daily. However, replace the face mask
immediately if it becomes worn or damaged.
Q:
Is the outbreak in Guangdong Province, China
linked?
A:
Extensive investigation is under way to better
understand the outbreak of atypical (unusual)
pneumonia that began in Guangdong province in
November 2002. Findings from this investigation
should help clarify possible links with cases
of SARS.
Q:
Could this result from bioterrorism?
A:
There is no indication that SARS is linked to
bioterrorism.
Q:
Should we be worried?
A:
This illness can be severe and, due to global
travel, has spread to many countries in a relatively
short period of time. However, SARS is not highly
contagious when protective measures are used,
and the percentage of cases that have been fatal
is about 5%.
Q:
Is it safe to travel?
A:
Observe good personal hygiene. Wash hands frequently.
Avoid visiting overly crowded places that are
poorly ventilated. Wear face mask. Travellers
should be aware of the main symptoms and signs
of SARS. People who have these symptoms and
have been in close contact with a person who
has been diagnosed with SARS, or have a recent
history of travel to areas where cases of SARS
have been spreading, should seek medical attention
and inform health care staff of recent travel.
Travellers who develop these symptoms are advised
not to undertake further travel until fully
recovered.
Q:
What is the purpose of a global travel advisory?
A:
The purpose of the advisory WHO issued on 15
March </entity/csr/don/2003_03_15/en>
is to tell people what SARS looks like and what
they need to report to a physician. The WHO
alert does not recommend cancellation of, or
change in, travel plans. Trade and tourism should
not be restricted. The purpose of the alert
is to heighten the awareness of travellers,
health authorities, and physicians, not to restrict
travel.
Q:
Could this be the next flu pandemic?
A:
Tests have not yet conclusively identified the
causative agent of SARS. The possible involvement
of an influenza virus was an initial concern.
Q:
What does WHO recommend?
A:
WHO recommends that global surveillance continue
and that suspected cases are reported to national
health authorities. WHO urges national health
authorities to remain on the alert for suspected
cases and followed recommended protective measures.
SARS patients should be isolated and cared for
using barrier nursing techniques and provided
with symptomatic treatment.
Q:
How can the public keep apprised of the situation?
A:
The public is advised to consult the home page
of the WHO website <http://www.who.int>
: for daily updates on the outbreak and relevant
press releases. More information is available
on the WHO SARS web page which is easily accessed
through the WHO home page or through: Severe
Acute Respiratory Syndrome (SARS) <http://www.who.int/csr/sars>.
This website will also provide daily updates
on SARS news.
Q:
What is WHO doing?
A:
WHO, through the Global Outbreak Alert and Response
Network, is working with its partners to track
the global dimensions of this outbreak and coordinate
efforts to quickly identify the causative agent,
improve diagnostic precision, and provide advice
on recommended treatment. WHO works closely
with health authorities in the affected countries
to provide epidemiological, clinical and logistic
support as needed.
Q:
What are the objectives of the international
response to the multi-country SARS outbreak?
A:
The aims of the international response, coordinated
by WHO, are to:
-
Contain
and control the outbreak
-
Identify
the causative agent
-
Identify
effective treatment regimes
-
Support
health care infrastructure in affected countries
by coordinating supplies and additional health
care workers if needed
-
Provide
information to health officials and address
public concerns
Q:
Are there any positive developments?
A:
A significant number of cases in Viet Nam, as
a result of good supportive care, have improved.
In addition, the global surveillance system
has proven to be a very sensitive and rapid
means of reporting of suspected cases. Health
authorities around the world are now alert to
the risk of SARS. Information on cases compiled
over the last three weeks is expected to
shed
new light on the behaviour of this disease.
Secondary outbreaks have to date been avoided
since global surveillance was put in place and
rapid isolation of cases undertaken.
