On this edition of ST Medical Monday, we offer a discussion of what is commonly referred to as "long-haul syndrome" or "long COVID." Our guest is Dr. Stan Schwartz, who's the chief medical officer of The Zero Card, a digital-health enterprise. He's also a former medical director of Tulsa's Warren Clinic. Dr. Schwartz joins us to expand on remarks that he recently made in a Tulsa World article about the issues, symptoms, and facts related to COVID-19 "long-haulers."
