Figure

Case determination algorithm used for analysis in the Centers for Disease Control and Prevention investigations of potential donor-derived strongyloidiasis, United States, 2012–2024. Each investigation begins with a trigger, either recipient positive posttransplant (1) or donor positive (2), and follows the algorithm to a designated case determination based on clinical, laboratory, and epidemiologic data and our case definitions. Determination categories include proven, excluded, NINDT, IWDT, probable, possible, and inconclusive cases. IWDT, intervention without disease transmission; NINDT, no intervention and no disease transmission.
