Dr. William Latimer speaks with Dr. John Glenn Morris, the director of the Emerging Pathogen Institute and a Professor of Infectious Diseases at the University of Florida. On this episode Dr. Morris discusses aerosols, what they are, and why they are important in understanding COVID transmission. He also discusses the Coronavirus, its origin, how new strains may arise and the idea that prior exposure to animal coronaviruses might stimulate pre-existing immunity to SARS-CoV-2 – reducing the likelihood of severe illness. Dr. Morris also discusses his unique childhood, growing up and living in Thailand, and how his experience with the cholera epidemics occurring at that time shaped his career.
