The Arizona health department has reported four cases of West Nile virus so far this year, although it’s still early in the season. That’s a far cry from 2021, when Maricopa County experienced the biggest outbreak of the virus ever reported in an American county.

Michael Riehle, a professor in the Department of Entomology at the University of Arizona, joined The Show to talk about what to expect later this summer.
