Notes from the Field: Strongyloidiasis at a Long-Term-Care Facility for the Developmentally Disabled - Arizona, 2015.
Strongyloides stercoralis is an intestinal nematode endemic in the tropics and subtropics. Infection is usually acquired through skin contact with contaminated soil, or less commonly, from person to person through fecal contamination of the immediate environment. Infections are often asymptomatic, but can result in a pruritic rash, respiratory symptoms (e.g., cough or wheeze), and gastrointestinal symptoms (e.g., diarrhea and vomiting). Immunosuppressed persons can develop strongyloides hyperinfection syndrome, which can be fatal (1). In June 2015, the Pinal County Public Health Services District in Arizona was notified of a suspected strongyloidiasis infection in a resident of a long-term-care facility for developmentally disabled persons. The patient had anemia and chronic eosinophilia. The patient's serum tested positive for S. stercoralis-specific immunoglobulin G (IgG) by a commercial enzyme-linked immunosorbent assay (ELISA) and at CDC by a crude antigen ELISA, a quantitative assay for detection of IgG against S. stercoralis. An investigation was conducted to determine the infection source and identify additional cases.
