Traveler's diarrhea: Rare Disease
Traveler's diarrhea is listed as a "rare disease" by the Office of

(NIH). This means that Traveler's diarrhea, or a subtype of Traveler's diarrhea,
affects less than 200,000 people in the US population.

estimated 10 million (DBMD1) ... see also overview of Traveler's diarrhea.

About prevalence and incidence statistics:
The term 'prevalence' of Traveler's diarrhea usually refers to the estimated population
of people who are managing Traveler's diarrhea at any given time.
The term 'incidence' of Traveler's diarrhea refers to the annual diagnosis rate,
or the number of new cases of Traveler's diarrhea diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
