The U.S. is in the grips of a third wave of the coronavirus pandemic and the numbers are rising at a rapid pace.

A vaccine is what public health officials are banking on to get us out of it.

With that, viral mutations are a concern.

My guest today is screening wastewater for the presence of COVID-19 to determine if the virus is circulating and if different strains of the virus are cropping up.

Joining me for today's show is Edwin Oh, PhD. Dr Oh is an Associate Professor at the University of Nevada, Las Vegas School of Medicine.
