NEWARK, N.J. — Businesses in Newark, New Jersey’s largest city, will face restrictions beginning Tuesday after the city’s positivity rate reached levels not seen since late May.

Newark Mayor Ras Baraka announced that non-essential businesses must close at 8 p.m. and restaurants must curtail indoor dining but can stay open for delivery and takeout.

Baraka, a Democrat, says testing from Oct. 11 to Oct. 18 showed Newark’s positivity rate at more than 11 percent, the highest since May 23.

Beauty salons, nail salons and barbershops can be open by appointment only. Gyms and health clubs must close for half an hour each hour for sanitizing. The restrictions will be re-assessed in two weeks.

In one Newark neighborhood, the positivity rate was more than 25 percent. The state’s positivity rate is roughly 5 percent.
