Traveler's diarrhea: Rare Disease

Traveler's diarrhea is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Traveler's diarrhea, or a subtype of Traveler's diarrhea, affects less than 200,000 people in the US population.

Incidence (annual) of Traveler's diarrhea:

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

Incidence Rate:

approx 1 in 27 or 3.68% or 10 million people in USA [Source statistic for calcuation: "estimated 10 million (DBMD1)" -- see also general information about data sources]

Incidence extrapolations for USA for Traveler's diarrhea:

10,000,000 per year, 833,333 per month, 192,307 per week, 27,397 per day, 1,141 per hour, 19 per minute, 0 per second. [Source statistic for calculation: "estimated 10 million (DBMD1)" -- see also general information about data sources]

Prevalance of Traveler's diarrhea:

Each year between 20%-50% of international travelers, an estimated 10 million persons, develop diarrhea. (Source: excerpt from Travelers' Diarrhea: DBMD)

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. For more information see about prevalence and incidence statistics.
