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.

<h3>What is
kidney failure?</h3>
A medical condition called kidney failure, also known as end-stage renal disease, occurs when the kidneys can no longer effectively filter waste materials from the blood and function at less than 15% of normal levels. Acute renal failure, which develops quickly and may resolve, and chronic kidney failure, which develops gradually and is frequently permanent, are the two categories of kidney failure.
Leg swelling, exhaustion, nausea, appetite loss, and confusion are possible symptoms. Uremia, elevated blood potassium, and volume overload are side effects of both acute and chronic failure. Heart disease, hypertension, and anemia are further chronic failure side effects.
