OKLAHOMA CITY (AP) — Oklahoma health officials reported 4,332 newly confirmed COVID-19 cases Sunday, and 22 more deaths linked to the disease caused by the novel coronavirus.

The Oklahoma State Department of Health said the new counts bring the state to a total of 237,668 case of the virus and 2,064 fatalities.

The actual number of cases is believed to be far higher because many people haven't been tested and some who get the disease don't show symptoms.

Over the last seven days, more than 16% of coronavirus tests in Oklahoma have come back positive, according to data from Johns Hopkins University.

State health officials are expecting as many as 33,00 doses of the Pfizer coronavirus vaccine to arrive in Oklahoma this week. Health care workers, long-term care providers and residents, paramedics, emergency medical technicians, and CVS and Walgreens staff who will administer the vaccine in long-term care facilities are set to be among the first inoculated.

For most people, the coronavirus causes mild or moderate symptoms that clear up within weeks. But for others, especially older adults and people with existing health problems, the virus can cause severe symptoms and be fatal. The vast majority of people recover.
