The following is [very] excerpted from _Natural History_
Defn: Incidence in the number of NEW cases of a disease reported per
unit time. It differs from Prevalence (cases/population) in that a rare but
long-term disease can have a low incidence but high prevalence, and the
reverse situation is possible.
Keeping that in mind, consider the following:
The incidence of AIDS among never-married men (not specifically Gays,
whose number is less easy determine than singles) in San Francisco and New
York is HIGHER than the incidence of Chicken Pox in Children. (Of course
NYC and SF account for 2/3 of the nation's cases.)
