Approximately 20% of new arrivals into Texas between June 2009 and May 2011 had positive ova and parasite stool samples during post-arrival screening exams. 1 Of 295 records that specified a parasite, more than 50% were positive for Giardia, 36% for Dientamoeba, 20% for Entamoeba, and 2% or less for Ascaris, Clonorchis, hookworm, Schistosoma, Strongyloides, and Trichuris. On serological tests, a more sensitive means of detecting Schistosoma and Strongyloides infection, of 272 refugees tested, 20% were positive for Strongyloides while only 2% of 64 tested were positive for Schistosoma. 1
