JUNEAU, Alaska (AP) — Alaska’s state-run ferry system is not requiring that passengers and crew wear face coverings in response to COVID-19 concerns, with a spokesperson saying rider numbers are low and social distancing on board is “easily attainable.”

CoastAlaska reported the Alaska Marine Highway System said it puts the health and safety of employees and passengers first. Cloth masks are available for crew members but not mandated, the system said.

State transportation department spokesperson Meadow Bailey said rider numbers are “very low, and social distancing is easily attainable for employees and passengers.” Two ferries currently are operating.

The system said it’s taken steps aimed at preventing the spread of COVID-19, including turning away passengers with flu-like symptoms.
