Dr. Rutul Dalal, medical director, Infectious Diseases, UPMC Susquehanna, on masking; what masks do, don’t do, and the myths. We’ll discuss the discussions of going back to school safely this fall, his work and concerns about fall sports and guidance UPMC trainers are offering at local schools. We’ll ask about his description of the contagiousness and severity of the current strain of coronavirus around here, and elsewhere. We’ll talk about the post July 4th ‘waiting period,’ and we’ll ask about the latest numbers.
