Authors of a new study conducted by researchers at the World Health Organization and Stanford University say there is no evidence of increased transmission of COVID-19 in Wisconsin following the state’s April 7 primary election.

The study, published on medRxiv, an online medical research platform operated by Cold Spring Harbor Laboratory, BMJ (a medical publisher), and Yale University, states that data suggest Wisconsin’s high-profile vote was a low-risk activity.
