Eosinophilia and the seroprevalence of schistosomiasis and strongyloidiasis in newly arrived pediatric refugees: an examination of Centers for Disease Control and Prevention screening guidelines.J Pediatr. 2010 Jun; 156(6):1016-1018.e1.JPed
The US Centers for Disease Control and Prevention has published refugee health guidelines that recommend examination of the absolute eosinophil count (AEC) to screen for asymptomatic schistosomiasis and strongyloidiasis. We examined the predictive validity of an AEC >400 cells/microL to identify refugees with serologic evidence for schistosomiasis or strongyloidiasis. Our study revealed that eosinophilia was not predictive of serologic evidence of either a Schistosoma species or Strongyloides stercoralis infection in the pediatric refugees examined in this study.
