Today’s guest is part of a growing body of experts calling on the Infection Prevention and Control (IPAC) community to accept that SARS-CoV-2 is not only transmitted by aerosols but that the airborne route may be the dominant mode of transmission. Dr. David Fisman, an epidemiologist and professor at the Dalla Lana School of Public Health, along with several colleagues, published Ten scientific reasons in support of airborne transmission of SARS-CoV-2. Dr. Fisman tells us that the evidence is clear, but the IPAC community has been slow to accept it.
