a city has a population of 300,000. of these, 15,000 have disease x, which is incurable. there are 1000 new cases and 600 deaths each year from the disease. there are 4500 deaths per year from all causes. the prevalence of this disease is given by:

Answer 1

Answer: The prevalence of the disease is 0.015

Step-by-step explanation:

Mathematically,

Disease Prevalence (P) = Incidence (I) * Average duration of the disease (D)

From the inquiry, the Incidence is 500/100,000 individuals-years

The course of the disease = 3 years

Preponderance = 500/100,000 * 3 = 0.015

hope this helped!
