Relative Risk Calculation Worksheet




Prior to completing this worksheet, review the lessons, reading and course text up to this point.

Also review the tables of calculations. Each question is worth five (5) points. There is only one

right answer for each of the ten problems.




1. The population in the city of Springfield, Missouri in March, 2014 was 200,000.

The number of new cases of HIV was 28 between January 1 and June 30th 2014.

The number of current HIV cases was 130 between January 1 and June 30th 2014.



The incidence rate of HIV cases for this 6 month period was:

A. 7 per 100,000 population

B. 14 per 100,000 population

C. 28 per 100,000 population

D. 85 per 100,000 population



Population: 200,000

New HIV cases=28

Current HIV cases=130



Calculating incidence rate for HIV= number of new cases of a disease =28

Number of the total people at risk ( entire population)=200,000



28/200,000 x 100,000=14

B. 28 per 100,000 population

C. 79 per 100,000 population

D. 130 per 100,000 population



Population: 200,000

New HIV cases=28

Prevalence rate= total number of people infected by disease at a specific time ( new + current HIV

cases) 130+28=158

Total population =200,000




158 x 100,000 = 79
