patients
Typical VS Atypical
Pneumonia
 Typical Pneumonia –
a lung infection,
where the alveoli in
the affected area fill
up with exudates
Typical VS Atypical
Pneumonia
 Atypical Pneumonia –
the tissue surrounding
the alveoli swells,
collapsing the alveoli,
reducing the blood
supply to the area, and
obstructing oxygen

which increases when taking a breath
How does SARS spread?
 Close person-to-person contact
 Physical contact with something that has been
contaminated by a SARS patient (such as
droplets)
Incubation period
After the virus enters the body, it requires 3 to 10
days incubation period before the disease
appears
Cause of SARS:
Coronavirus
Coronavirus Family
 Halo or crown-like (corona) virus
 Cause mild to moderate respiratory
illnesses such as common cold
 Able to survive in dry air for up to 3 hours
 Can be killed by exposure to ultra-violet
light
 Mutate easily, and each mutation triggers
off an epidemic of respiratory disease
Transmission of Coronavirus
 Airborne Transmission :
 Coronavirus family has
the property of surviving
in dry air/surfaces for up
to 3 hours. In these
conditions, the virus
crystallizes, and can
float in the air like dust.
Transmission of Coronavirus
 The SARS virus
seems to enter the
body through the
eyes, nose and
mouth.
Treatments on SARS
Recent Treatments:
• Antivirals such as oseltamivir or ribavirin
• Steroids (orally or intravenously) in
combination with ribavirn and other
antimicrobials
Being developed
