Case #290 – December, 2010

A 31-year-old man was admitted to a local hospital with fever, chills, myalgia, and fatigue. His travel history included a two week work-related trip to Cambodia and a one week vacation in Connecticut immediately after that trip. His symptoms began about 3 days after returning from Connecticut. He indicated that he did take anti-malarial prophylaxis while in Cambodia but failed to take the remainder of his medication before going to Connecticut. Blood smears were ordered, stained with Giemsa, and examined. Figures AD show what was observed at 1000x oil magnification. What is your diagnosis? Based on what criteria?
