"Additionally, it is important for all of us to protect not only ourselves but also to be considerate of others at increased risk for severe COVID-19 and those who are not yet able to be vaccinated. Wearing a mask in indoor public transportation settings will provide protection for the individual and the community," she said.
Causes in the US may be far fewer than during the omicron-related wave but have started to increase in recent weeks. This week, the seven-day moving average of new cases is over 60,000 and the CDC believes this is largely a result of omicron's new subvariant, BA.2.
America's federal transportation mask mandate was first implemented in January 2021 and was extended multiple times.
After it was overturned by a federal judge in Florida last month, major US airlines and airports, rideshare services and Amtrak quickly dropped their mask-wearing policies.
In New Zealand, under the orange setting of the COVID-19 Protection Framework, there are several transport-related instances where masks are mandated. Masks must be worn on public transport and domestic flights, at indoor arrival and departure points like bus stops or airports and in taxis or rideshare vehicles.
