More Beloit residents have tested positive for the coronavirus than in any other Rock County municipality, but Janesville claims the higher mortality rate. After months of back and forth between county and municipal leaders, the Rock County Public Health Department has started publishing community-specific data on its website for Janesville and Beloit. The county’s remaining cities, villages and towns have been lumped together in a separate category. Epidemiologist Nick Zupan said health department officials hope to offer data for smaller municipalities in the future. Municipal data confirms the coronavirus has reached more Beloit residents.
