New Jersey has recorded 1,263 cases of in-school transmission of the virus since schools began to reopen in September, according to the New Jersey Health Department. Less than 1 percent of the state’s K-12 students and teachers had a coronavirus case linked to in-school transmission, while the positivity rate among the general population was 11 percent.
New York is hosting upcoming N.B.A. playoff games inside Madison Square Garden and the Barclays Center in Brooklyn, where at least 50 percent of seating will be for vaccinated people, Governor Cuomo said. Masks and social distancing will be required in the section for unvaccinated fans.
Mr. Cuomo said that the Tribeca Festival would return next month and its final night would be held at Radio City Music Hall with full capacity for vaccinated filmgoers and no masks required. The New York City Marathon will return in November at 60 percent capacity, or about 33,000 runners.
The guidance the C.D.C. issued on Thursday said that it was no longer necessary for fully vaccinated people to mask or maintain social distance in many settings. The change set off public confusion and drew objections from some local officials and labor unions, including the country’s largest union of registered nurses. A number of major U.S. retailers have already lifted mask requirements, essentially turning to an honor system that relies on unvaccinated people to keep their masks on in public.
Businesses in New York can still set individual policies and some will require masks. They do not have to do vaccination checks.
“They can check, they can ask at the door, they can ask when you are seated at the table, or not,” Mr. Cuomo said. “There is no mandatory compliance the state is imposing on the private vendors.”
The state’s health department is keeping its recommendation to wear masks indoors where the vaccination status of nearby people is not known. It applies to retail stores, food services, offices, gyms and fitness centers, amusement and family entertainment, hair salons, barber shops and other personal services, among others.
