The incidence rate of a nonfatal disease is 500/100,000 person-years. People usually have the disease for an average of 3 years, at which time the disease resolves spontaneously. Estimate the prevalence of this disease using this information. Assume that the population is in a steady state.

Respuesta :

Answer:

The prevalence of the disease is 0.015

Explanation:

Mathematically,

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

From the question, the Incidence is 500/100,000 person-years

Duration of the disease = 3 years

Prevalence = 500/100,000 * 3 = 0.015
