OKLAHOMA CITY (AP) — Four more people have died in Oklahoma after contracting the coronavirus, bringing the state's death toll to 311, state health officials reported on Saturday.

Another 111 Oklahomans have tested positive for the virus as the total number of cases reached 5,960, the State Department of Health reported. The true number is likely higher because many people have not been tested, and studies suggest people can be infected and not feel sick.

The four new deaths were a man in the 65-and-older age group, who died in Oklahoma County, and three who died in Tulsa County — a man in the 65-and-older age group, a woman in the 65-and-older age group, and a man in the 50-to-64 age group.

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, and death.
