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.

Traveler's diarrhea Prevalence: Book Excerpts

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)

Diarrhea - Case 17-1: 2-Month-Old Boy: III. Incidence and Epidemiology
(Pediatric Complaints and Diagnostic Dilemmas)

The incidence of inguinal hernia is estimated to be between 1% and 5%, or approximately 10 to 20 cases per 1,000 live births. The incidence in premature infants is significantly higher, approaching 30%. The ratio of boys to girls is 6:1. In boys, the right side is more frequently involved than the left, presumably due to the embryologic origin of inguinal hernias through a patent processus vaginalis and the fact that the right testis descends later during gestation than the left. In both boys and girls, 60% of inguinal hernias occur on the right, 30% on the left, and 10% bilaterally. Inguinal hernias are usually diagnosed during the first year of life, most frequently during the first month. There is often a family history of inguinal hernia. Undescended testes may be associated with inguinal hernias. Other conditions associated with inguinal hernias include Ehlers-Danlos syndrome, cystic fibrosis, congenital cytomegalovirus infection, and testicular feminization. There is no apparent ethnic or racial predisposition to inguinal hernia. Incarcerated inguinal hernias occur most frequently before 6 months of age, are less common after 2 years of age, and are rare after 5 years of age.

Diarrhea - Case 17-4: 15-Month-Old Boy: III. Incidence and Epidemiology
(Pediatric Complaints and Diagnostic Dilemmas)

The annual incidence of neuroblastoma is approximately 8 per 1 million children younger than 15 years of age. The median age at diagnosis is 22 months, and 95% of cases are diagnosed by the age of 10 years. Neuroblastoma accounts for approximately 6% of all pediatric tumors. There is a slight male preponderance, with a ratio of 1.2:1. There also appear to be cases that are familial in nature and manifest at a younger age, with a median age of 9 months at diagnosis. These tumors derive from postganglionic sympathetic cells found in the paraspinal sympathetic ganglia and in the adrenal chromaffin cells. Neuroblastoma and ganglioneuroblastoma represent the malignant forms of these neural crest tumors, whereas ganglioneuroma represents the most benign form, with no metastatic potential.

Chronic Diarrhea: Chronic Diarrhea - epidemiology
(The 5-Minute Pediatric Consult)

  • Chronic diarrhea seen in the tropics and developing countries is more likely infectious in nature than in the US.
  • Gender and genetic factors do not play a significant role in most cases of chronic 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. For more information see about prevalence and incidence statistics.
