Health care workers in Oklahoma who have tested positive for the novel coronavirus but are asymptomatic — meaning they are not showing any symptoms — can continue working at hospitals and long-term care facilities, but only as a “last resort,” according to health officials in the state. “Because some Oklahoma hospitals and nursing homes are experiencing staffing shortages, the Oklahoma State Department of Health is allowing asymptomatic staff who previously tested positive for COVID-19 to continue working,” Travis Kirkpatrick, deputy commissioner of the Oklahoma Department of Health, in a statement, according to The Oklahoman.
