Prevalence and Incidence of Amebiasis
Amebiasis: Rare Disease
Amebiasis is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Amebiasis, or a subtype of Amebiasis,
affects less than 200,000 people in the US population.

Amebiasis:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
E. histolytica exists in two forms: a cyst (which can survive outside the body) and a trophozoite (which can't survive outside the body). Transmission occurs through ingesting feces-contaminated food or water. The ingested cysts pass through the intestine, where digestive secretions break down the cysts and liberate the motile trophozoites within. The trophozoites multiply and either invade and ulcerate the mucosa of the large intestine or simply feed on intestinal bacteria. As the trophozoites are carried slowly toward the rectum, they are encysted and then excreted in feces. Humans are the principal reservoir of infection.
Amebiasis occurs worldwide but is most common in the tropics, subtropics, and other areas with poor sanitation and health practices. Incidence in the United States averages between 1% and 3% but may be higher among homosexuals and institutionalized people, in whom fecal-oral contamination is common.

Amebiasis:
Amebiasis - epidemiology
(The 5-Minute Pediatric Consult)
- Spreads person to person via fecal–oral transmission
- Less common modes of transmission include food and water borne infection
- Sexual transmission can occur among men who have sex with men.
Amebiasis - incidence
Amebiasis accounts for 40–50 million cases of colitis worldwide and leads to 40,000–110,000 deaths annually.
Amebiasis - prevalence
- The estimated prevalence in the US is 4% although there have been no recent serosurveys in developed countries.
- Worldwide distribution involving an estimated 10% or more of the world’s population. Most common in tropical areas, with infection rates as high as 20–50%. The highest morbidity and mortality are seen in developing countries in Central America, South America, Africa, and Asia.

About prevalence and incidence statistics:
The term 'prevalence' of Amebiasis usually refers to the estimated population
of people who are managing Amebiasis at any given time.
The term 'incidence' of Amebiasis refers to the annual diagnosis rate,
or the number of new cases of Amebiasis 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.
