Consider the figure attached, showing seven people studied between point A and B, and where the position of the numbers marks the onset of the disease in the people depicted. Supposing the total number of persons observed between A and B was 100, calculate the  Point prevalence at A and B , Period prevalence and what  disease measures could be computed for analytic studies?

Expert Solution
Step 1Point prevalence

Prevalence of an illness = Number of people in the sample with illness/Total number of people in the sample

Point prevalence at A(1,2,&3 are ill) = 3/100 =0.03

Point prevalence at B(2,6&7 are ill) = 3/100= 0.03
