Case #514 - April, 2020

A 24-year-old female exchange student from Guinea reported to the clinic with headaches, itchy skin, and enlarged lymph nodes. She recalled multiple painful insect bites in her country prior to her travel to the United States. A rapid diagnostic test for malaria performed at the clinic was negative. Smears were subsequently made and stained with Wright-Giemsa. Figures A and B show what was observed on a thin blood smear at 1000x oil magnification. What is your diagnosis? Based on what criteria?
