Coronavirus Pandemic Update 104: COVID 19 Reinfection & Immunity

The first documented COVID 19 reinfection has been reported in Hong Kong verified by genetic sequencing. Dr. Seheult of https://www.medcram.com explains the importance of this patient’s symptoms (he was asymptomatic with the second infection) and how immunity to viruses typically builds over time with subsequent exposures or vaccines. Dr. Seheult also discusses comparisons to previous viruses such as smallpox that have caused large numbers of deaths among populations without any prior exposure. (This video was recorded August 26, 2020).
