Minnesota's COVID-19 case count jumped to 115 with 26 new infections announced Friday as state officials grappled with the logistics of obtaining testing materials and health care supplies.
It is the biggest one-day increase in confirmed case numbers since COVID-19 testing began in the state, but it is unclear when these newly reported cases were infected. It can take up to two weeks for disease symptoms to develop.
COVID-19 illnesses are expected to continue to spread, with state health officials saying that they are working with University of Minnesota researchers to help predict the speed and breadth of new infections, as well as measure the effectiveness of the many community mitigation efforts that were designed to prevent a quick surge.
That monitoring has been hampered by a lack of testing supplies that are needed to broaden the scope of disease detection. With the help of private labs, including the Mayo Clinic, a backlog of 1,800 patient samples has been winnowed to 1,300 that are awaiting processing.
The new coronavirus was first detected in Minnesota two weeks ago with cases that were imported by travelers, and then it moved to some of their close contacts.
Now it is increasingly being spread through community transmission where the source of the infection often can't be determined.
At least 15 confirmed cases are known to have spread that way, but there are likely to be many more.
In the past two days, cases have been identified in five more counties, Chisago, Clay, Fillmore, Mower and Rice. But infections have likely spread beyond the 21 counties that have confirmed cases.
