Different measures of disease are useful to evaluate and assess public health programs and needs in different situations. For each of the following scenarios, (a) state which measure would best support your goal, and (b) explain why you chose that measure.
Measures of disease:
I = incidence rate
P = prevalence
L = lifetime prevalence
M = crude mortality rate (crude death rate)
R = simple sex ratio
