To work, quarantine measures and other steps to control disease require broad public buy-in. If that vital ingredient is lacking, all the best practices grounded in the latest science from leading doctors and researchers simply aren't going to work.
Minnesota does not yet have COVID-19 under control and on Thursday, the day after Gov. Tim Walz announced a controversial light touch on the reopening "dial," there were 32 new deaths reported in the state. That's the highest daily tally to date.
To send that number back to zero, energetic cooperation is required from the public. There's no vaccine or proven treatment for COVID-19, so the best defenses are hand-washing, social distancing and face coverings.
Minnesota's mitigation measures still hew to reopening guidance from the White House and the U.S. Centers for Disease Control and Prevention.
But if public support for them is fracturing, and it appears to be, Walz needs to reconsider current strategy, particularly for restaurants. Flexible guidelines followed by more people are better than rigid ones that increasingly inspire open defiance or covert end-runs around them.
There's been plenty of political point-scoring by legislators who decry restrictions on businesses but have yet to offer up a detailed plan of their own to guard against COVID-19's spread. But this week brought game-changing developments.
On Wednesday, Walz's dial-turning kept in place a 10-person gathering size limit for churches, synagogues and mosques. And while outdoor dining with restrictions was allowed for restaurants, inside dining remains a no-go, disappointing struggling restaurant owners and their patrons.
Soon after the governor's announcement, the Minnesota Catholic Conference sent a terse rejection to Walz. In it, the state's Roman Catholic bishops give parishes permission to resume the public celebration of mass on May 26. Their plan to do so allows for gathering sizes of more than 10 where sanctuaries are large enough to maintain social distancing.
