Thirteen more people have died of COVID-19 in Minnesota, health officials reported Sunday.

The Minnesota Department of Health reported a net increase of 741 new confirmed coronavirus infections, according to a data release on Sunday morning.

Residents of long-term care and assisted-living facilities accounted for nine of the newly announced deaths, which came on a volume of about 1.7 million completed tests. Statewide, the pandemic's toll reached 1,919 deaths.

The latest Minnesotans to die ranged in age from 60 to 99. Hennepin and Ramsey counties each reported three death. St. Louis and Waseca counties each had two deaths. Anoka, Freeborn and Kanabec counties each reported one death.

The numbers show 241 patients were hospitalized, compared with 247 on Saturday; 136 patients required intensive care, compared with 140 on Saturday. Daily tallies for hospitalized patients in Minnesota have been trending down or holding steady in recent weeks.

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, 84,311 people have tested positive in Minnesota and 6,931 people have been hospitalized.

People at greatest risk from COVID-19 include those 65 and older, residents of long-term care facilities and those with underlying medical conditions.

Those health problems range from lung disease and serious heart conditions to severe obesity and diabetes. People undergoing treatment for failing kidneys also run a greater risk, as do those with cancer and other conditions where treatments suppress immune systems.

Most patients with COVID-19 don't need to be hospitalized. The illness usually causes mild or moderate sickness and many lack symptoms.

Numbers released Sunday show health care workers have accounted for 9,146 cases statewide. A total of 77,461 Minnesotans who were infected with the novel coronavirus no longer need to be in isolation.

Confirmed cases have been reported in all of the state's 87 counties.
