Epidemiologist Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota, is sought out by journalists, scientists and policymakers who consider him one of the world's most insightful experts on COVID-19.
But for five Twin Cities kids, he's just Grandpa.
Summers have been a time to make memories for Osterholm, 67, and his grandchildren, who range in age from 2 to 10. This summer, though, he's only seen them twice since March, and only then from a proper 6-foot distance.
"I miss them dearly," he said. "Not being able to hug the kids is tough. I miss the physical and emotional contact."
But Osterholm is adhering to the Centers for Disease Control and Prevention's recommendation that those 65 and older (who are at higher risk of having a severe case or dying if they contact COVID-19) should limit contact to people in their household. That means steering clear of children who might be asymptomatic, inadvertent carriers of the virus.
He also understands why some grandparents duck that directive.
"Everyone's getting pandemic fatigue. They start rationalizing, they think, 'I don't know anyone who died or had a serious illness,' " he said. "I see how grandparents can slip."
If an international authority on the pandemic is tempted to break the rules, it's no wonder that the resolve of an everyday Nana and Papaw may be starting to fray.
