Cuomo, Murphy, Lamont 'reviewing' new CDC guidance on masks By FOX 5 NY Staff Published CDC Director Dr. Rochelle Walensky said the agency updated its mask-wearing recommendations based on unpublished new data. NEW YORK - Officials in New York, New Jersey, and Connecticut are reviewing the U.S. Centers for Disease Control and Prevention's course correction on its guidance for wearing masks before issuing any new mandates — if any. The CDC announced on Tuesday that even if you're vaccinated you should go back to wearing a mask indoors in parts of the country where the delta variant is fueling surges in infections. The CDC also recommended that all teachers, staff, students, and visitors at schools nationwide — regardless of vaccination status — wear masks indoors.
