ST. PAUL (AP) — Minnesota health officials reported 871 newly confirmed coronavirus cases on Sunday, the fourth straight day the state has reported more than 700 new cases.

The spike in new daily cases was one of the largest in Minnesota since May, the Star Tribune reported. But the increase came on a volume of about 16,272 completed tests, which is much higher than daily test tallies in May.

The new cases raise the total of confirmed infections in Minnesota since the pandemic started to 51,153.

Positive cases and deaths continue to climb in southwest Minnesota. Eight new cases were reported in Lyon County as it recorded a milestone, surpassing the 400-mark for total cases.

And Pipestone County recorded two more deaths over the weekend and now has eight total.

In other area counties, Murray County added eight more cases over the weekend, Pipestone five, Yellow Medicine County two and Lincoln County 1.

Three new deaths were reported Sunday, raising Minnesota’s death toll to 1,574. One of the newly reported death was a resident of a long-term care or assisted-living facility. Of COVID-19 deaths in Minnesota, 1,205 or about 77% are among residents of long-term care or assisted-living facilities.

A total of 273 patients were hospitalized Sunday, down from 287 on Saturday. The number of patients requiring intensive care remained at 115 on Sunday. Daily counts for hospitalized patients in Minnesota have been trending down or holding steady in recent weeks.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia.
