Many of the base's nearly 10,000 workers already have been teleworking as a result of the coronavirus pandemic. The 55th Wing also recently closed the Kenney Gate and added screening measures at the StratCom and Bellevue gates.
The screening process includes questions about current health, signs of any symptoms and potential interaction with someone exposed to the virus.
