Federal health officials have recently expanded their masking recommendations for more than just public indoor spaces. Now they are recommending that people mask up when they are in crowded outdoor areas, where transmission rates are high.
Dr. Michael Osterholm spoke with News Talk 830 WCCO's Chad Hartman about the switch in guidance ahead of the start of the Minnesota State Fair and what he thinks about it.
"First of all, we have to go back to 'why are we even talking about it,'" Osterholm said. "This Delta variant, this particular mutated form of the virus, is highly highly infectious."
With the increase in transmissibility being a factor, Osterholm talked about the effect that large gatherings outdoors have had on COVID-19 numbers this summer. He went on to share that there have been four identified events that have caused outdoor air transmission.
"It just points out that this virus is highly infectious and being in close contact with people in the outdoor environment is surely a major risk factor," he shared.
