Updated Status for H&S BN, HQMC, Henderson Hall, 31 October 2022

Face Mask Usage on Joint Base Myer Henderson Hall
Joint Base Myer-Henderson Hall has transitioned to Health Protection Condition Bravo

Effective Mar. 1, 2022, JBM-HH rescinds its Aug. 2, 2021 policy requiring face coverings indoors. When the CDC COVID-19 Community Level is low in the county where a DoD installation or facility is located, indoor mask-wearing is not required for DoD personnel or visitors. As of Mar. 1, 2022, both the District of Columbia and Arlington County have been designated “low” by the CDC.

Individuals may choose to still wear a mask regardless of the CDC COVID-19 Community Level. Regardless of the CDC COVID-19 Community Level, DoD force health protection guidance for workplace access and mask wearing for DoD personnel with symptoms, a positive test, or exposure to someone with COVID-19 remains in effect. All other force health protection guidance remains in effect, including guidance regarding workplace access, occupancy levels, physical distancing, travel, and meetings. Individual must follow more rigorous workplace mask mandates when commanders and supervisors determine that it is required to protect health and safety in the workplace, such as mask wearing by health care workers. Accordingly, the mask policy for Rader Health Clinic and the Cody Child Development Center has not changed – all personnel and visitors, regardless of vaccination status, are still required to wear a mask indoors at these facilities until further notice.
