Arizona Republic Her first symptoms — a scratchy throat and cough — were so mild that Jannie Cox "totally blew them off" on Dec. 27, when they first emerged. Three days later, the 74-year-old Tucson resident could no longer deny it: She was sick. Her throat had become fiercely sore, she had flu-like body aches, and it was clear she was either catching a cold, or worse. That same day, she tested positive for COVID-19 infection and her husband, 75-year-old David Syverson, was developing symptoms, too. Cox, a retired health care foundation executive, knew what she wanted for herself and her husband: an intravenous infusion of a relatively new treatment therapy for outpatients with mild to moderate COVID-19 called monoclonal antibodies.
