Effective February 25, 2022, CDC is exercising its enforcement discretion to not require that people wear masks on buses or vans operated by public or private school systems, including early care and education/child care programs. CDC is making this change to align with updated guidance that no longer recommends universal indoor mask wearing in K-12 schools and early education settings in areas with a low or medium COVID-19 Community Level. School systems at their discretion may choose to require that people wear masks on buses or vans.
The problem here is the problem we have faced throughout the pandemic. Power is claimed by the CDC that it does not possess. This relaxation of the “enforcement” means that it can be re-imposed at any time.
