Answer

Globally, prevalence rates of strongyloidiasis are as high as 40% in certain areas where suitably moist soil and improper disposal of human waste coexist, especially West Africa, the Caribbean, and Southeast Asia, as well as Colombia, tropical sections of Brazil, and temperate sections of Spain. [27, 28] The disease is estimated to affect 100-200 million people worldwide in 70 countries.

The international prevalence of larva currens among patients with strongyloidiasis varies, with rates in the range of 30-90% in Southeast Asia. High rates of larva currens are also reported in Latin America. A stool and serosurvey for S stercoralis conducted in a community in the Peruvian Amazon region found strongyloidiasis due to S stercoralis in the stool of 69 (8.7%) of 792 participants. [29]
