The traveling farm wife

In late summer, a 77-year-old woman was hospitalized after 9 days of chills, low-grade fever, fatigue, and generalized weakness. She did not have abdominal pain, coughing, diarrhea, dyspnea, jaundice, nausea, rashes, sore throat, vomiting, or weight loss. Her medical history was significant for well-controlled type 2 diabetes mellitus, dyslipidemia, hypertension, hypothyroidism, osteoarthritis, and osteoporosis. She took alendronate, calcium, levothyroxine, lisinopril, metformin, naproxen, and simvastatin. None of these had been initiated in the weeks prior to onset of symptoms.
