As leading infectious disease experts in the U.S. warn that the coronavirus is not going anywhere, some officials in parts of the country have paused reopening plans and threatened renewed shutdowns.

On Monday, Gov. Andrew M. Cuomo of New York again called on local governments to enforce the state’s restrictions on reopening, though he did not single out New York City. A day earlier, he said that the state had been deluged with some 25,000 complaints about businesses that were “in violation of the reopening plan.” Governors in Oregon and Utah said last week they were pausing reopening plans after seeing cases rise. “I don’t want to go forward and then take a step backward,” Gov. Gary Herbert of Utah said on Thursday, adding that he did not intend to enact any additional restrictions on businesses. And Gov. Kate Brown of Oregon said on Thursday that her state was placing county applications for reopenings on hold for a week, in order to give public health experts time to ensure that the virus wasn’t spreading too quickly.

Experts have said that without a vaccine about 70% of the population would need to be infected and develop immunity in order to stop the virus’s spread, a concept called herd immunity. The current number of confirmed cases in the U.S. is over 2 million, less than 1% of the U.S. population, according to a New York Times database.
