Employee had been infected with a disease and was contagious when he had attended a work event. he had close contact with all 40 other meeting attendees (assume all were exposed) shortly after, 22 people developed symptoms of the disease. of the 22, that developed symptoms 4 had to be hospitalized because of severe symptoms. all 40 attendees (besides the original employee) later submitted to a blood test and it was later found that 33 had been infected with the disease. calculate the following (do not include the index case): (a) inefectivity of the desease = ) pathogenicity of the desease = ) virulence of the desease =

Inefectivity of the desease = 82.5 %

(b) Pathogenicity of the desease = 55%

(c) Virulence of the desease = 10%

Step-by-step explanation:

Given data:

Total number of employee 40

Total number of employee infected to disease 22

Total number of employee with severe symptoms 4

Later, it was found total number of employee infected to disease is 33

A) Inefectivity is ability to established infection

b) pathogenicity of disease is ability of organism to cause disease

c) virulence of disease is ability of pathogen to cause severe disease

number one is the correct answer

step-by-step explanation: dogs and cats are mentioned, no other animals

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
