OBJECTIVES:


CASE:

A 36 year old previously healthy woman from El Salvador presents with 10 days of fevers and headache. Her fevers come and go, and range up to 40C.  Her headache is mild without associated photophobia, vision changes or neck pain/stiffness. She  otherwise denies sinus pain, congestion, cough, SOB, abdominal pain, diarrhea, dysuria or skin changes. She initially started taking some left over ciprofloxacin for the first 4 days but stopped at the recommendation of her PCP who felt it was likely viral.  After arriving in the US to visit friends, she presented to the ED on day 9 of her fevers. She was discharged from the ED last night and called back for blood cultures positive for GNRs.

She is otherwise healthy except for occasional UTIs. She is on no chronic medications but has been taking APAP as needed for fever and headache. She lives in El Salvador and recently traveled to Guatemala. She denies an substance use.
