B.    (A/P) × 100,000

C.    (P/D) × 100,000

D.    (P/A) X 100,000

D.    None of the above

  1. Which factors can decrease an observed prevalence?

A.    Decrease in incidence

B.    Better reporting of diagnoses

C.    Improved cure rates of disease

D.    A & C only

  1. Prevalence measures do not aid in:
