Based on the results of the study shown below, the epidemiologist has reason to worry because the incidence rate increased over four times the previous level as shown below:
- number of HIV cases = 440 persons
- new incidence rate = 2.25 per 1000 persons
<h3>What is prevalence and incidence rate?</h3>
Prevalence rate is the proportion of persons in a population who have a particular disease or attribute at a specified point in time or over a specified period of time.
- Prevalence rate = number of cases/total population × 100%
Incidence rate is the proportion of new cases of a condition observed within a given period of time.
- Incidence rate = number of new cases/population at risk × 1000
- population at risk = total population - previous cases
The number of people who had HIV in January 2012 is calculated as follows:
- number of HIV cases = prevalence rate × total population
number of HIV cases = 2.2% × 20000
number of HIV cases = 440 persons
Incidence rate between February 2012 and January 2013 is calculated as follows:
Incidence rate = 50/(20000 - 440) × 1000
Incidence rate = 2.25 per 1000 persons.
Based on the new incidence rate, the epidemiologist has reason to worry because the incidence rate has increased over four times the previous level.
