From the article:Ryan noted that instead of lockdowns, the country has “put in place a very strong public policy around social distancing, around caring and protecting people in long-term care facilities.”“What it has done differently is it has very much relied on its relationship with its citizenry and the ability and willingness of its citizens to implement self-distancing and self-regulate,” Ryan said. “In that sense, they have implemented public policy through that partnership with the population.”I'm not certain that a similar partnership is widely possible in the U.S. as things now stand.(And on a personal note: one of my husband's oldest friends died of Covid-19 in Sweden two days ago.)
I also assume you've read--in the same article--the higher numbers of infections and deaths from Covid-19 than its stricter Nordic neighbours.
Just because I link to something doesn't mean I'm totally in agreement with it. The idea is to get as much discussion going as possible, since I do think what we don't know about all of this is significantly greater than what we think we know.
