SARS

Whats SARS
- Severe acute respiratory syndrome (SARS)
- is corona virus as a serious form of pneumonia
resulting in acute respiratory distress. - Also most probably causes the common harmful
sickness, even severe ill will probably die.
3
- According to researchers in Hong Kong the SARS
virus actually come from animals and spread
rapidly over the world in the end of February in
2003.
4
How SARS spread?
- The virus spreads direct and indirect ways by
person to person. - Direct infection
- It spreads through the air, particularly
with someone who is SARS will definitely infect
many people around such as, respiratory , the
skin contact cause contamination of infectious
droplets and then touching your eyes, nose or
mouth eg. Sharing of eating. - Indirect infection
- Contact with any objects containing virus for
example, a contaminated phone and even lead to
infection on eyes, nose or mouth.
5
Diagnostic of SARS
- 1. Molecular tests (PCR)
- Polymerase chain reaction (PCR) can detect
genetic material of the SARS-CoV in various
specimens eg. Blood, body tissue. - The primer is a key piece as the genetic material
detection whether it contain corona virus or not. - Principally, existing PCR tests are very specific
but lack sensitivity
6
- 2. Antibody tests
- The antibodies produced in response to the SARS
corona virus infection. - Two different types of antibodies (IgM and IgG)
appear and change in level during the course of
infection. - They can be undetectable at the early stage of
infection - IgG usually remains detectable after resolution
of the illness. - Positive show antibody test with a previous
- infection with SAR-CoV.
- Negative no detection of antibody after
- 21 days.
7
- ELISA (Enzyme Linked ImmunoSorbant Assay)
- a test detecting a mixture of IgM and IgG
antibodies in the serum of SARS patients yields
positive results reliably at around day 21 after
the onset of illness. - IFA (Immunofluorescence Assay)
- a test detecting IgM antibodies in serum of SARS
patients yields positive results after about day
10 of illness. - This test format is also used to test for IgG.
This is a reliable test requiring the use of
fixed SARS virus on an immunofluorescence
microscope. - However, this two methods are being developed,
but are not commercially available yet !
8
- 3. Cell culture
- Virus in specimens (such as respiratory
secretions, blood or stool) from SARS patients
can also be detected by inoculating cell cultures
and growing the virus. - Once isolated, the virus must be identified as
the SARS virus with further tests. Cell culture
is a very demanding test, but currently - (with the exception of animal trials) only means
to show the existence of a live virus. - Positive indicate the presence of live CoV in
the sample test. - Negative do not exclude SARS.
9
Symptoms Work
- To beginning with, sick in fever gt38 C,
- (the incubation period range from 2 to 7 days
after exposing the virus. However, it can take as
long as 14 days for symptoms to appear.) - ?
- Headache, muscle soreness body or an overall
feeling of discomfort - ?
- Dry cough and a trouble breathing
- ?
- 4. Death
10
- In some cases have reported the incubation
periods of as many as 14 days, but this is not
currently considered the norm. - Some people also experience mild respiratory
symptoms, which will be acute breathing of lung
problem.
11
Treatment
- Researchers have not yet found any anti-viral
drugs because antibiotics are not effective
against viral infections. - SARS patients having pneumonia will be treated by
putting on mechanical ventilation to help them
breathe. - Therapy has included antivirals as steroids in
combination with ribavirin and other
antimicrobials. - However, ribavirin does not inhibit virus growth
or cell spread of the new coronavirus.
12
Prevention
- Put on masks to reduce the chance of spread of
infection - Carefully dispose of materials used to wipe
respiratory secretions - Keep hands clean and wash hands properly
- Maintain good indoor ventilation
- Build up good body immunity
- Adhere to good personal hygiene practices
13
Conclusion
- SARS is a corona virus as to cause respiratory
illness, contacting by respiratory and body
contact that show fever, headache, discomfort
feeling after 10 days, then developed a dry cough
to become the lung damage. - Although the scientists have been finding some
efficient vaccines to relieve the SARS disease,
still the vaccines work not well. - Hopefully, the scientists will be able to
discover the vaccine which definitely get the
corona virus extinction.
