A Case of Chronic Q Fever Treated With Doxycycline and Trimethoprim-Sulfamethoxazole With a Favorable Outcome.

In United States, Q fever cases increased from < 50 to 200 from 2000-2019. Case: 31-year-old female with fever after exposure to unpasteurized milk. Investigation revealed positive Q fever IgG. Trimethoprim-sulfamethoxazole and doxycycline were started due to QTc prolongation. Evidence is limited on treatment without hydroxychloroquine, and the use constraints might prompt additional studies.
