Earlier in the day, a commercial aircraft carrying gloves, masks, gowns and other medical supplies from Shanghai touched down at Kennedy International Airport in New York, the first in a series of roughly 20 flights that White House officials say will funnel much-needed goods to the United States by early April.

FEMA will provide the majority of the supplies to New York, New Jersey and Connecticut, with the rest going to nursing homes in the area and other high-risk areas across the country, a White House spokesman said.

While the supplies will be welcomed by hospitals and health care workers — some of whom have resorted to rationing protective gear or using homemade supplies — they represent just a tiny portion of what American hospitals need.

The Department of Health and Human Services has estimated that the United States will require 3.5 billion masks in the event of a pandemic lasting a year.

The pandemic has started a race among foreign governments, American governors and mayors, good Samaritans and opportunists to acquire protective gear, ventilators and other goods from China, the source of more than one-third of medical supplies in the United States in 2019.

Trump on Sunday acknowledged that he would delegate calls to governors — typically Democrats — that he has had personal disagreements with, doubling down on his assertion that the governors need to treat him “fairly.”.

Trump said.

Covid-19 patients ‘don’t have to worry’ about big medical bills, health insurers say.President Trump at a White House briefing on Sunday praised two of the nation’s largest health insurers, Cigna and Humana, for agreeing to protect their customers from out-of-pocket costs if they need treatment for Covid-19.

Trump said the companies don’t “waive co-pays too easily, but we asked them and they did it.”.

Cordani, the chief executive of Cigna, in an interview before the White House briefing.

Last week, another large insurer, Aetna, now part of CVS Health, said it would also waive cost-sharing related to hospital stays.

Cuomo of New York said on Sunday.

Trump denied on Sunday that the prospect of a quarantine was a threat.

“I didn’t go around threatening,” he said during a White House briefing.

He raised the idea because the region has the most confirmed coronavirus cases in the United States, but he offered no details about how his administration would enforce it.

Cuomo said on Sunday.

And at least 20 states now have more than 1,000 known cases within their borders.

Cuomo said the total number of cases in New York was 59,513, an increase of nearly 7,200 confirmed from the day before.

More than half of the cases, or 33,768, are in New York City.

With global cases passing 675,000, Syria reports its first coronavirus death.

As the coronavirus pandemic has sickened more than 678,900 people worldwide and killed at least 31,971, the Syrian government reported the first death from the virus in its territory on Sunday, about a week after announcing its first confirmed case.

The outbreak, if uncontrolled, could shred a health care system already enfeebled by more than nine years of civil war.

But Syria has now confirmed 10 cases, including the patient who died on Sunday, according to a state news agency.

The health care system would be rapidly overwhelmed in a full-blown outbreak, aid workers say.

has delivered testing kits and protective equipment for health care workers, but medical aid groups that operate in the country have found their efforts to prepare hampered by the new restrictions on working hours and on gathering.

Italy reported more than 97,689 cases of the coronavirus, an increase of more than 5,200 from Saturday.

England’s deputy chief medical officer said on Sunday that Britons may be under some form of lockdown for six months or longer, warning that the country faces a second wave of coronavirus if they are lifted too quickly.

Britain had over 17,000 confirmed coronavirus cases as of Sunday — including Prime Minister Boris Johnson, who was initially reluctant to introduce social distancing measures in the country, and Prince Charles, the heir to the British throne.

The company said on Friday that around 180 people, including 110 members of the crew, have flulike symptoms and two have tested positive for Covid-19, the disease caused by the coronavirus.

The ship received special authorization from Panama’s Ministry of Health and will transit the canal under “special considerations and for humanitarian reasons,” the canal authority said on Twitter.

Pelosi and White House exchange accusations of early denial of the coronavirus’s gravity.

On Sunday, Speaker Nancy Pelosi put the blame for the nation’s flawed response to the pandemic squarely on President Trump.

Trump, for his part, has played down the spread of the virus until recently, and has repeatedly touted unproven treatments while contradicting his administration’s scientific experts on how lethal the virus is and how quickly it may be contained in the United States.

Lawmakers are floating the possibility of another emergency response bill.Over fewer than four weeks, Congress and the White House have agreed to billions of dollars in emergency aid, a significant expansion of the social safety net and a $2 trillion stimulus, the largest economic response package in modern American history.

Trump had suggested the states might be quarantined — a more severe restriction — but offered no details about how his administration would enforce it.

Trump said on Twitter that he had spoken to the governors of the three states and that the quarantine “will not be necessary.” He said that he had asked the C.D.C.

said Sunday that all states “should be beginning to plan” for the possibility of conducting their elections by mail because of the coronavirus pandemic, and suggested there was a chance the general election this fall would need to be conducted by mail-in ballots.

Biden, who is seeking the Democratic nomination for president, said on NBC’s “Meet the Press.” “I think we should be looking into all-mail ballots across the board to begin with, because it’s an easier way for people to vote, but whether or not that’s required across the board in all 50 states and territories, I’m not sure yet.”.

Biden also said that if he were president, he would be using the Defense Production Act more aggressively to secure needed items like masks and ventilators, suggesting that President Trump was not doing all he could to help doctors, nurses and emergency responders.

Gee of the United States District Court, came after plaintiffs in a long-running case over the detention of migrant children cited reports that four children being held at a federally licensed shelter in New York had tested positive for the virus.

“The threat of irreparable injury to their health and safety is palpable,” the plaintiffs’ lawyers said in their petition, which called for migrant children across the country to be released to outside sponsors within seven days unless they represent a flight risk.

Around the United States, about 3,600 children are in shelters operated under license by the federal Office of Refugee Resettlement, and about 3,300 more at three detention facilities for migrant children held in custody with their parents, operated by the Immigration and Customs Enforcement agency.

fell behind on coronavirus testing.As the coronavirus spread across the United States between late January and early March, large-scale testing of people who might have been infected did not happen because of technical flaws, regulatory hurdles, business-as-usual bureaucracies and lack of leadership at multiple levels.

Together, the challenges resulted in a lost month, when the United States squandered its best chance of containing the coronavirus’s spread
