Rationale for change

"Formulas
Prevalence = (incidence) × (average duration of disease)
If the population is in a steady state, the relationship between incidence rate (IR), prevalence (P), and the average duration of the disease (T) can be described mathematically as follows:
P/(1 - P) = IR × T
OR
IR = (P/(1 - P))/T
If the disease is extremely rare, P ≈ IR × T
Number of new cases per unit time = IR × (population at risk)"
