The aim of this study is to highlight the potentially fatal risk of Strongyloidiasis Hyperinfection Syndrome for hospitalized immigrant patients with moderate to severe COVID-19 disease and undiagnosed Strongyloidiasis. We reviewed electronic medical records of immigrants from 2010 to 2022 and extracted the number of patients with eosinophilia, strongyloidiasis and COVID-19 infection, outpatient and hospitalized. While 885 outpatients were diagnosed with eosinophilia, only 356 (40.2%) were tested for strongyloidiasis and 160 (44.9%) yielded a reactive serology. COVID-19 infection was reported in 6,412 patients. 1135 (17.7%) of these patients sought hospital care. Patients with undiagnosed strongyloidiasis are at risk for a potentially fatal parasitosis if treated with systemic corticosteroids for COVID-19. This supports clinical guidelines in hospital settings for those with severe COVID-19. Strongyloidiasis should be considered by taking a thorough travel or migration history and testing before giving immunosuppressive drugs.
