The Centers for Disease Control and Prevention reversed course on July 27 on

Many parts of New York, including Long Island, are considered areas with "high transmission" and would fall under the new guidance. See the CDC map of transmission areas here.

New York State had adopted the CDC mask and social distancing guidelines in May that said fully vaccinated people no longer had to wear a mask or social distance except where it's required by law or by businesses, or in certain public places. And several businesses updated their mask policies accordingly.

But many companies have revised their mask policies again, citing the spread of the virus and the contagious delta variant. Here are some of the mask-wearing policies we know of at major retailers around Long Island.

This is not a full list of stores across the Island, and some have not yet announced changes to their mask policies. We will be updating this list as we learn more.
