Over the course of the pandemic, our vocabulary has gained a specific word that has come to represent great concern and distress in our global community. Variant. In the context of COVID-19, it has meant a resurgence in viral infections, resistance to treatments, and the risk of an ineffective vaccine.  This week, we’re going to look at the science behind SARS-CoV-2 variants with Earl Brown. He’s a professor emeritus at the University of Ottawa and also a colleague with whom I’ve performed research and published on emerging pathogens such as SARS and avian flu. Our discussion will not only enlighten you but also reveal aspects of the nature of variants you won’t hear anywhere else.  While we try to identify all the potential questions you might have regarding wastewater testing, I’m sure you will have more. Which is why I hope you reach out to me on Twitter, by Email, or via voice message at Speakpipe.com/SASS.
