Response to question 1
SARS stands for Severe Acute Respiratory Syndrome which is a severe form of
pneumonia. It is caused by SARS virus that causes acute respiratory disabilities that can
sometime cause death. Epiville is an educational tool that has been designed specifically for
enhancing the web-based learning outcomes. SARS virus belongs to a group of corona virus
that also causes common cold. It can spread via cough or sneeze from the infected persons to
the healthy persons. From the case study it is thus, clear that the individuals who either had a
direct contact with the infected person or had cared for the person are at highest risk for the
disease (Epiville.ccnmtl.columbia.edu, 2019).
Response to question 2
From the case study, it is clear that the people who are suffering from the disease
spread the disease to normal healthy person. For example, a 70 year old man who was
suffering from respiratory disorders was looked after a doctor and a nurse who fell sick
within week (Who.int, 2019). This example shows the pattern in which the virus affects the
healthy people. It is also seen that the individuals who either have a pet at their house or do
not clean their house regularly also fall prey to SARS virus. This is because research has
shown that animal source virus of SARS is found in people who are infected with SARS.
This virus is common in household pets and other insects commonly found in household such
as cockroaches (Who.int, 2019).
Response to question 3
Thus, the conclusions that can be drawn on the mode of transmissions of the diseases
is through the contact with the infectious droplets as the route of infection is through the
mucous membranes in the eyes, nose and mouth or exposure to the poisonous fomites
