Overview
The global prevalence of Strongyloides is unknown, but experts estimate that there are between 30–100 million infected persons worldwide, mainly in tropical and subtropical countries. Infection is more common in the pediatric age group (ages 2-10 years).[1][2][3]
Epidemiology and Demographics
Prevalence
- The global prevalence of Strongyloides is unknown, but experts estimate that there are between 30–100 million infected persons worldwide.
Incidence
- In the United States, a series of small studies in select populations have shown that between 600-1,000 per 100,000 individuals sampled were infected.
- Studies in immigrant populations have shown a much higher percentage of infected persons, ranging from 460-1,000 per 100,000 individuals.
Geographic distribution
Strongyloides is known to exist on all continents except for Antarctica, but it is most common in the tropics, subtropics, and in warm temperate regions.
Age
Strongyloidiasis occurs in all age groups but it is more common in the pediatric age group (ages 2-10 years).
Gender
Males and females are equally affected.
