Case #499 – September, 2019

A 5-year-old child was taken to a children’s hospital with presumed febrile illness (symptoms and travel history were not provided). A blood smear was made and stained with what appeared to be Wright-Giemsa. The stained slides were sent to the State Public Health Lab which submitted images to CDC/DPDx for diagnostic assistance (Figures AH). What is your diagnosis? Based on what criteria?

The images of this case were kindly provided by the Pennsylvania Department of Health; the exact age of the patient has been edited for the purpose of this case.
