The determination of biological sex occurs at the genetic level in which one of our 46 chromosomes can either be an X or a Y. But that one variance can lead to countless differences between the two. Now, thanks to COVID-19, we have another as it has become clear XX and XY respond to the virus differently.  Last year, Eileen Scully outlined those differences and I’ve asked her to come on the show to share them with us. She is an assistant professor of medicine at the Johns Hopkins University School of Medicine and has been researching infection, immunity, and biological sex for years particularly in terms of HIV infection. Now she’s taking us on a journey into the possible consequences of COVID-19 infection based on biological sex.  While I do what I can to get to the bottom of the differences, I’m sure you will have questions. Which is why I hope you reach out to me on Twitter, by Email, or via voice message at Speakpipe.com/SASS.
