New CDC mask guidance adds to a confusing patchwork of rules across US

Some businesses lift mask mandates while others keep them; New York will drop its mandate indoors for vaccinated people

The patchwork system for mask guidance in the US will continue despite federal authorities' decision last week to say people fully vaccinated against Covid-19 mostly do not need to wear masks indoors.

Companies including Walmart and Starbucks lifted mask mandates in response. Others, including Gap, plan to keep them in place. States including New Jersey and California also plan to keep mask rules in place.
