FARGO, N.D. (AP) — North Dakota health officials on Friday confirmed the state’s first death due to COVID-19, the disease caused by the new coronavirus.

A Cass County man in his 90s who had underlying health conditions died, the state Health Department said. He acquired the virus through community spread, in which officials can’t determine how a patient got infected.

“Each of us has a responsibility to help prevent the spread of COVID-19 in North Dakota and protect those most vulnerable to the disease — our elderly and individuals with underlying health conditions,” Gov. Doug Burgum said in statement. “We’re all in this together.”

Officials reported early Friday that 13 people had been hospitalized with the virus. For most people, the coronavirus causes mild or moderate symptoms, which can include fever and cough but also milder cases of pneumonia, sometimes requiring hospitalization. The risk of death is greater for older adults and people with other health problems.
