The COVID-19 pandemic has impacted everyone across this planet, has tested our ability to adapt, develop and role out vaccines and figure out efficient ways to test and monitor our entire population. When testing is limited, what is the best way to understand the spread of a virus in a large population? In this episode we learn about Wastewater Surveillance and how you can test samples from our sewers to understand where the virus has spread. We get insight from Dr. Steve Hrudey the Chair of the COVID-19 Wastewater Coalition from the Canadian Water Network. Dr. Hrudey helps us understand how this technology works, where it's been used before, and how it can be used in the future. You don't have to be a math whiz to know that being able to test an entire population with one sample versus testing everyone individually means a lot less work. This technology is becoming even more important as we begin tracking new variants within our communities and begin planning to protect ourselves for any potential future pandemics.
