Effective February 25, 2022, CDC previously announced that it would use
enforcement discretion to not require people to wear a mask in outdoor
areas of conveyances (if such outdoor areas exist on the conveyance) or
while outdoors at transportation hubs. CDC will continue to evaluate the
requirements of its Order and determine whether additional changes may be
warranted.
While in indoor areas of conveyances or while indoors at transportation
hubs, people are not required to wear a mask under the following
circumstances:
– while eating, drinking, or taking medication for brief periods of time;
– if, on an aircraft, wearing oxygen masks is needed because of loss of
cabin pressure or other event affecting aircraft ventilation;
– when experiencing difficulty breathing or shortness of breath or
feeling winded, until able to resume normal breathing with the mask; when
vomiting until vomiting ceases; or if wearing a mask interferes with
necessary medical care such as supplemental oxygen administered via an
oxygen mask.
