As a result of a court order, effective immediately and as of April 18, 2022, CDC’s January 29, 2021 Order requiring masks on public transportation conveyances and at transportation hubs is no longer in effect. Therefore, CDC will not enforce the Order. CDC continues to recommend that people wear masks in indoor public transportation settings at this time.
