A New Study Pinpoints a Cause of Long-Haul COVID Symptoms


An Attack on Mitochondria? Authors:  MAGGIE RYAN February 2, 2022 As the pandemic continues, long COVID-19 remains very prevalent (affecting between 31 and 69 percent of COVID-19 patients) and somewhat bewildering because there’s no clear connection between the severity of a patient’s initial symptoms and how long they might linger. That was one thing that Irina Petrache, MD, chief of the […]
