Question

Why is it important to test patients for antibodies to COVID-19?

Answer #1

Currently several methods are being used for Covid-19 like viral test or antibody test etc. An early detection cannot be done by anti-bodies methods as its take couple of weeks to generate in the body after an infection to cope with.

Some time Covid-19 patient does not show any symptoms as it is asymptomatic in lots of people and if they have or ever had Covid-19 in the past then anti-body test would be the best method, as it will show presence of anti-bodies in the patient as a result of viral infection. Such anti-bodies can be used as therapeutic agent through plasma therapy in active patients.

How
Monoclonal antibodies can be considered as an option to treat COVID
19?

Give your opinion about using Monoclonal antibodies in the
treatment of COVID 19?

Antibodies against COVID-19 have 90% chance of
preventing reinfection. Probability of getting infected and sick
without antibodies is 50%. It is estimated that in a country 25% of
all people have COVID-19 antibodies.
a) If a person is selected at random, find the
probability that (s)he is at the danger of contracting the
disease.
b) Draw Vennâ€™s diagram and decision tree for the
situation. Explain.

A firm has developed a new test for COVID-19. If someone has
COVID-19, the test finds it 93% of the time. If someone does not
have COVID-19 the test returns a positive COVID-19 8% of the time.
If the 30% of the populations has COVID-19, what is the probability
of someone selected at random having COVID-19 if they tested
positive? Give your answer to four decimal places.

The University of Minnesota and the Mayo Clinic are close to
developing a test for COVID-19 antibodies in our blood (They may
have already accomplished this by the time you do this extra
credit).
Individuals may have COVID-19 antibodies in their blood because
these antibodies are produced by A. T-cells, B. b-cells, C.
Neutrophils in order to A. Prepare for possible
infection, B. Signal to the adaptive immune system that a foreign
antigen is present, or C. Combat a foreign...

A drive through at the Mt. Nittany Medical Center tests patients
in their car for COVID 19. They have found that 15% of the patients
who are tested for COVID 19 test positive for the disease; the
remaining patients test negative. Use this information to answer
the following questions.
1.If 20 patients are tested, what is the probability that three
of them test positive? (Use 4 decimal places)
2.Let X = # of patients who test positive for COVID 19...

Q3]
The duration of COVID-19's disease for many patients ranges from 5
to 20 days until death; the average is 7 days with a standard
deviation of 3 days. The hospital randomly chose the medical
reports of 20 dead COVID-19's patients from the database and
recording the average duration. Find the following probabilities?
1-The average of COVID-19's duration is less than 6
days.
2-The average duration of COVID-19' lies within 2 days for the
population mean u=7.
3-The average of...
