China edges closer to normal as stores in the epicenter city of Wuhan begin reopening.

NEW YORK — The U.S. death toll from the coronavirus climbed past 3,500 Tuesday, eclipsing China’s official count, as the deepening crisis in New York hit close to home for the governor when he disclosed, teary-eyed, that his brother, CNN anchor Chris Cuomo, has become infected.

“But there’s a lesson in this,” Gov. Andrew Cuomo said of his 49-year-old brother, now quarantined in his basement. “He’s an essential worker, a member of the press so he’s been out there. If you go out there, the chance that you get infected is very high.”

Elsewhere around the world, hard-hit Italy reported that the infection rate appears to be leveling off and new cases could start declining, but that the crisis is far from over. Spain, too, struggled to fend off the collapse of its hospital system. Vladimir Putin’s Russia moved to crack down on quarantine violations and “fake news” about the outbreak. And China edged closer to normal as stores in the epicenter city of Wuhan began reopening.

Worldwide, more than 800,000 people have been infected and over 39,000 people have died, according to a tally kept by Johns Hopkins University. Italy and Spain accounted for half the deaths, while the U.S. had around 3,550 by midday, overtaking China’s official toll of about 3,300.

New York was the nation’s deadliest hot spot, with about 1,550 deaths statewide, the majority of them in New York City.

A Navy hospital ship with 1,000 beds that docked in New York on Monday was expected to begin accepting non-coronavirus patients on Tuesday. A 1,000-bed emergency hospital set up at the Javits Convention Center began taking patients Monday night. And the Billie Jean King USTA National Tennis Center, the site of the U.S. Open tennis tournament, was being transformed into a hospital.

Chris Cuomo tweeted that he suffered from fever, chills and shortness of breath and that he would be doing his shows from his basement. He said that he worried about infecting his family, but added: “We will all beat this by being smart and tough and united!”

Close to 80,000 former nurses, doctors and other professionals are already said to be stepping forward to help New York. New York City also sought to bring in 250 out-of-town ambulances and 500 paramedics and emergency medical technicians to help its swamped EMS system.

The city’s ambulances are responding to about 6,000 calls a day, or 50% more than average, authorities said. Fire Commissioner Daniel Nigro said a five-day stretch last week was the busiest in the history of the city’s EMS operation.

Figures on deaths and infections around the world are supplied by government health authorities and compiled by Johns Hopkins. But the figures are regarded with skepticism by public health experts because of different counting practices, a lack of testing in places, the numerous mild cases that have been missed, and perhaps government efforts to downplay the severity of the crisis.

For example, in Italy, where the death toll was put at about 12,400, the country’s emergency coordinator, Domenico Arcuri, acknowledged that officials don’t have a handle on how many people outside of hospitals are contracting the virus and how many are dying at home or in nursing homes.

Still, there was a glimmer of hope in Italy: Dr. Silvio Brusaferro, the head of Italy’s national institutes of health, said that three weeks into a national lockdown, the hardest-hit country in Europe is seeing the rate of new infections level off.

“The curve suggests we are at the plateau,” he said. “We have to confirm it, because arriving at the plateau doesn’t mean we have conquered the peak and we’re done. It means now we should start to see the decline if we continue to place maximum attention on what we do every day.”

With the country’s health care system buckling under the pressure, an intensive care field hospital, built in just 10 days, was unveiled at the Milan fairgrounds.

“We made a promise and we kept it,” said the head of the project, former civil protection chief Guido Bertolaso, who ended up catching the virus while on the job and had to work from his hospital bed.

In Russia, lawmakers approved harsher punishments, including prison of several years, for violating quarantine rules and spreading misinformation. The chief doctor at Moscow’s top hospital for coronavirus patients said he tested positive for the virus, a week after shaking hands with Putin.

Spain reported more than 840 new deaths, pushing the death toll above 8,000 and forcing Madrid to open a second temporary morgue after an ice rink pressed into service last week became overwhelmed.

Dozens of hotels across Spain have been turned into recovery rooms for patients in less-serious condition, and authorities are building field hospitals in sports centers, libraries and exhibition halls.

A 12-year-old girl became the youngest person to die in Belgium, though it was not disclosed whether she suffered from any underlying condition.

In Florida, the Holland America cruise line pleaded with state officials to let two ships dock and carry off the sick and the dead. But Gov. Ron Santis said on Fox News: “We cannot afford to have people who are not even Floridians dumped into South Florida using up those valuable resources.”

Dozens on one of the ships have reported flu-like symptoms, and four people have died.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough. But for others, especially older adults and people with existing health problems, it can cause severe symptoms like pneumonia.

China on Tuesday reported just one new death from the coronavirus and 48 new cases, claiming that all new infections came from overseas. In Wuhan, people were ready to “revenge shop” as the Chinese city that was once at the center of the outbreak reopened.

Still, Dr. Takeshi Kasai, the World Health Organization’s regional director for the Western Pacific, cautioned, however, that the risk in Asia and the Pacific “will not go away as long as the pandemic continues.”

“This is going to be a long-term battle and we cannot let down our guard,” Kasai said. “We need every country to keep responding according to their local situation.”

In Serbia, Hungary and other nations, concerns were rising that populist leaders were using the situation to seize more power and silence critics.

“A state of emergency — wherever it is declared and for whatever reason — must be proportionate to its aim, and only remain in place for as long as absolutely necessary,” said human rights expert Ingibjörg Sólrún Gísladóttir of the Organization for Security and Cooperation in Europe.
