April 2020 — A temporary public health sign outside a Walgreens store instructs customers to follow CDC guidance and remain six feet apart while inside and outside the building. Such signage became widespread in the United States in March 2020, when retailers adopted distancing protocols in response to the COVID-19 pandemic. The six-foot standard reflected federal public health recommendations intended to reduce airborne transmission of the SARS-CoV-2 virus in shared indoor spaces. National pharmacy chains like Walgreens remained open as essential businesses, implementing floor markers, occupancy limits, plexiglass barriers, and posted guidance like this to manage customer flow and maintain access to prescriptions and basic goods during lockdown periods.
