A 46-year-old male presents to his general practitioner (GP) reporting cyclical fever

A 46-year-old male presents to his general practitioner (GP) reporting cyclical fever, occurring every three days. He also experiences shivers, sweats, and muscle aches. There is no significant past medical or family history. His travel history includes a recent month-long trip to sub-Saharan Africa. The trip was unplanned so he did not take any medications or use mosquito-repellent nets. No abnormalities are noted on examination.
