Q:

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 = ____(b) Pathogenicity of the desease = ____(c) Virulence of the desease = ____

Accepted Solution

A:
Answer: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 40Total number of employee infected to disease 22Total number of employee with severe symptoms 4Later, it was found total number of employee infected to disease is 33A) Inefectivity is ability to established infection [tex]= \frac{33}{40} \times 100  = 82.5%[/tex]b) pathogenicity of disease is ability of organism to cause disease[tex]=\frac{22}{40}\times 100 = 55%[/tex]c) virulence of disease is ability of pathogen to cause severe disease[tex]=\frac{4}{40}\times 100 = 10%[/tex]
