Case #478 – October, 2018

A 4-year-old boy returned from a summer vacation in Tanzania with his parents with symptoms of fever and chills. He was evaluated at a clinic in St. Louis, Missouri where blood smears were ordered, stained with Giemsa and examined at 1000x magnification with oil. Images captured from the stained thin smear were sent to the DPDx Team for identification. Figures AF show what was observed in some of the images submitted. What is your diagnosis? Based on what criteria?
