Minnesota surpassed 50,000 confirmed cases of COVID-19 Saturday, with the last of its 87 counties reporting its first positive test on the day a statewide mask-wearing mandate took effect to help slow the spread of the coronavirus.
Sparsely populated Lake of the Woods County in far northern Minnesota stood for more than a month as the only county in the state without a confirmed case. Now, it is one of six with fewer than 10 cases, according to Saturday's data release from the Minnesota Department of Health.
The data again reflected an uptick in the number of new COVID-19 cases as the volume of tests completed in the state continues at high levels.
"50,000 laboratory-confirmed cases is a milestone we hoped we would not reach," Dr. Ruth Lynfield, state epidemiologist, said in an e-mail. "With high levels of the virus circulating in our communities, we will continue to have spread and cases, and there will be some Minnesotans who develop severe and fatal illnesses."
The Health Department reported five more deaths from COVID-19, bringing the statewide toll to 1,571 since the start of the pandemic. Four of the newly reported deaths were residents of assisted-living or long-term care facilities.
COVID-19 is a viral respiratory illness caused by a new coronavirus that surfaced late last year. Since the first case was reported in Minnesota in early March, 4,889 people have been hospitalized.
The mask mandate that took effect Saturday applies to most indoor spaces outside people's homes, as well as outdoor spaces where workers can't stay 6 feet from one another. It exempts children younger than 2 and people with certain medical conditions. It also specifies conditions where a face covering can be temporarily removed.
Minnesota is one of roughly 30 states that have imposed some degree of mask-wearing requirements, which have been widely supported by physicians and public health experts. They point to studies such as a report this month in the Journal of the American Medical Association, which found a link between slowing the growth in cases and requiring masks for all health care workers at a group of hospitals in the Boston area.
