Edwards Air Force Base in California will move from Health Protection Condition Alpha to Bravo beginning June 21, according to the base’s website and Facebook page.

“With the surrounding community levels moving into the medium [COVID-19 risk] level, Edwards Air Force Base will move into HPCON Bravo,” the Facebook post said.

HPCON Bravo means there is an outbreak or heightened exposure risk of COVID-19, according to the base’s website.

Screening testing will be reinstated for entry to DOD facilities for anyone who is not vaccinated. Organizations will also limit building occupancy to 80%, the website said.

Masks are still not required in indoor settings, the website said.
