Presumptive treatment and screening for strongyloidiasis, infections caused by other soil- transmitted helminths, and schistosomiasis among newly arrived refugees

Strongyloides parasites, other soil-transmitted helminths (STH), and Schistosoma species are some of the most common infections among refugees [1, 2]. Among refugees resettled in North America, the prevalence of potentially pathogenic parasites ranges from 8% to 86% [1, 2]. This broad range may be explained by differences in geographic origin, age, previous living and environmental conditions, diet, occupational history, and education level. Although frequently asymptomatic or subclinical, some infections may cause significant morbidity and mortality. Parasites that infect humans represent a complex and broad category of organisms. This section of the guidelines will provide detailed information regarding the most commonly encountered parasitic infections.intestinal-parasites-domestic-h.pdf201
