Case #153 – April, 2005

A 32-year-old male from Nigeria had been visiting some relatives in the United States for approximately a week. He went to a local emergency room for headaches, nausea, and general weakness and fatigue. Blood was drawn by fingerstick and thick and thin blood films were made. Images from the thick smears were captured and sent to CDC for confirmation. Figures A and B show what was seen on the Giemsa stained thick film when it was examined. What is your diagnosis? Based on what criteria? What additional steps would you recommend to achieve a definitive diagnosis?
