Michael Osterholm is a frequent flier, often racking up more than 200,000 miles a year.
But as the number of U.S. coronavirus cases climbs, the director of the Center for Infectious Disease Research and Policy at the University of Minnesota is sticking close to home.
"At this point, I have now ended all my travel," Osterholm said.
He is practicing what he and other public health experts preach: social distancing. This means staying home as much as possible, avoiding large crowds and keeping a 3- to 6-foot distance between you and others when you go out.
Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, has recommended social distancing for all Americans ages 60 and up, as well as those with an underlying health condition that puts them at greater risk. Officials have also suggested this practice for everyone living in areas where coronavirus has begun to spread locally.
There's no doubt that social distancing is a bit awkward (avoiding handshakes or even elbow bumps, turning down invitations), disappointing (missing a much-anticipated event or gathering) and isolating (like a snow day that lasts for weeks). But health experts say it is important because it can slow the virus' spread, providing a chance to keep the caseload at a more manageable level for hospitals and care providers.
"Social distancing is the spacing out of people in places in such a way that you greatly reduce the likelihood that an uninfected person will come in contact with an infected person," explained Osterholm. "It's really a very simple concept. It's just about space and time. So, when you have large crowds together in closed spaces, the likelihood that they are all sharing air with each other, both that which we breathe in and breathe out, is markedly increased. This virus is transmitted very easily via the respiratory route."
Social distancing hasn't been widely recommended in Minnesota in years, aside from nursing homes that might restrict visitors when influenza transmissions are high, said Craig Hedberg, a professor who researches foodborne illness and infectious disease outbreaks at the University of Minnesota's School of Public Health.
