■ New York and New Jersey again have the nation’s highest rates of coronavirus infection.

They are tops in new infections per capita among U.S. states

A year after becoming a global epicenter of the coronavirus pandemic, New York and New Jersey are back atop the list of U.S. states with the highest rates of infection.

Even as the vaccination campaign has ramped up, the number of new infections in New Jersey has crept up by 37 percent in a little more than a month, to about 23,600 every seven days. About 54,600 people in New York tested positive for the virus in the last week, a number that has begun to inch up recently.

The two states now rank Nos. 1 and 2 in new infections per capita among U.S. states. New Jersey has been reporting about 647 new cases for every 100,000 residents over the past 14 days. New York has averaged 548.

The situation in New York and New Jersey mirrors a national trend that has seen case numbers inch up in recent days. The U.S. is averaging nearly 62,000 cases a day, up from 54,000 two weeks ago.

Neither state is experiencing anything like what they saw last spring, when hospitals — and morgues — were overflowing. And like the rest of the country, both are in a much better place than in January, at the peak of the pandemic’s winter spike.

But the lack of improvement in recent weeks has raised concerns that the states are opening too quickly and people are letting down their guard, just as potentially more contagious variants of the virus are circulating more widely.

“When we’re seeing leveling off of cases or increase, that’s when it’s a time to rethink policies,” said Roy Gulick, chief of the infectious diseases division at Weill Cornell Medical College and New York-presbyterian Hospital/weill Cornell Medical Center.

In February, New York Gov. Andrew Cuomo allowed the state’s largest stadiums to host sporting events and concerts again, albeit at 10 percent of normal capacity. New York City movie theaters have been allowed to reopen. Restaurants can now operate at 50 percent capacity in New York City and 75 percent capacity elsewhere in the state. Indoor fitness classes have resumed, too.

New Jersey Gov. Phil Murphy has led a similar reopening, with the state’s restaurants also allowed to operate at half capacity and barbers, salons and other personal care businesses resuming trade.

That’s happened in other parts of the country, too.

Utah, Alabama, Arkansas and Indiana will end mask mandates in early April, joining states including Arizona, Texas, Mississippi, Montana and Iowa that have eliminated face covering requirements in recent weeks. Some states are allowing businesses to operate at full capacity.
