SARS
Introduction
• SARS, a highly contagious
disease that originated in
China, has killed more than
200 people and infected
nearly 3,900 others in 25
countries. The majority of SARS
related deaths have occurred
within the Pacific Rim, but more
cases are cropping up in
North America nearly 200
nonfatal cases of SARS have
been reported in the United
States, and 14 Canadians have
died from the disease.
History
•
The epidemic of SARS appears to have started in Guangdong
Province, China in November 2002. The first reported case of SARS or
iginated in Shunde, Foshan,Guangdong in November 2002,and
the patient, a farmer, was treated in the First People's Hospital of
Foshan (Mckay Dennis). The patient died soon after, and no definite
diagnosis was made on his cause of death. Despite taking some
action to control it, Chinese government officials did not inform the
World Health Organization of the outbreak until February 2003.
Symptoms
• Initial symptoms are flu-like
and may include fever,
lethargy symptoms, cough, sore
throat, and other nonspecific
symptoms. The only symptom
common to all patients appears
to be a fever above 38 °C (100 °F).
Shortness of breath may
occur later. The patient has
symptoms as with a cold in the
first stage, but later on they
resemble influenza.
Spread
• SARS originated in the Far East and has travelled
across the globe by those infected by it. The virus can
spread by close contact (meaning having cared for,
having lived with, or having had direct contact with
respiratory secretions and body fluids of a person
with SARS).SARS is spread through 'droplet
transmission', that is when someone infected coughs
or sneezes droplets into the air and someone else
inhales them. It is also possible to transfer the
infection through from objects that have become
contaminated.
Prognosis
• During the pandemic, approximately 25% of people with SARS
developed severe respiratory failure or ARDS. In the general
population, people with SARS had approximately a 10% chance of
dying. Deaths in children were rare. However, up to 50% of
people with underlying medical conditions died; peopleover 50
years old also had a similar death rate. Unfortunately, many people
who eventually recover from SARS have had pulmonary fibrosis,
osteoporosis, and femoral necrosis and are disabled, according to
reports from China.
Prevented
• There is no vaccine to date. Isolation
and quarantine remain the most
effective means to prevent the
spread of SARS. In addition,
handwashing, use of universal
precautions, disinfection of surfaces
for fomites, and use of a surgical mask
are recommended. Avoid contact
with bodily fluids. Annual influenza
vaccinations and 5-year
pneumococcal vaccinations may be
beneficial; but vaccinations only
reduce or weaken the severity of SARS
infection.
