The transport mask mandate may have been overturned by a Florida ruling on February 18 but the Centres for Disease Control have made their advice clear; mask up, even if you don't have to.
While America's Department of Justice works to appeal the Florida ruling, the Centers for Disease Control and Prevention reiterated their recommendation on Tuesday that people should continue to mask up in certain places.
Based on "currently available data" the CDC said it was beneficial to wear a mask in "crowded or poorly ventilated locations," like aeroplanes and airports.
Given the data surrounding the efficacy of masking when it comes to protecting yourself and others from Covid-19, the recommendation is no surprise.
"CDC continues to recommend that all people — passengers and workers, alike — properly wear a well-fitting mask or respirator in indoor public transportation conveyances and transportation hubs to provide protection for themselves and other travelers in these high volume, mixed population settings," said CDC Director Dr Rochelle Walensky in a statement.
"We now have a range of tools we need to protect ourselves from the impact of COVID-19, including access to high-quality masks and respirators for all who need them."
