NEW YORK -- The coronavirus outbreak has thrown 10 million Americans out of work in just two weeks in the swiftest, most stunning collapse the U.S. job market has ever witnessed, and the public health crisis deepened in New York City, where a funeral home in a hard-hit neighbourhood had 185 bodies stacked up Thursday -- more than triple normal capacity.

The dire news of a record-shattering 6.6 million new unemployment claims, on top of last week's unprecedented 3.3 million, came as economists warned unemployment could reach levels not seen since the Depression.

Competition for scarce ventilators, masks and other protective gear seemed to grow more desperate and deaths mounted with alarming speed in Italy, Spain and New York, the most lethal hot spot in the United States, with nearly 2,400 lives lost.

Worldwide the number of confirmed infections hit another gloomy milestone -- 1 million, with more than 50,000 deaths, according to the tally kept by Johns Hopkins University. But the true numbers are believed to be much higher because of testing shortages, many mild cases that have gone unreported and suspicions that some countries are covering up the extent of their outbreaks.

The mounting economic fallout almost certainly signals the onset of a global recession, with job losses that are likely to dwarf those of the Great Recession more than a decade ago.

"My anxiety is through the roof right now, not knowing what's going to happen," said Laura Wieder, laid off from her job managing a now-closed sports bar in Bellefontaine, Ohio.

About half of all working Americans report some kind of income loss affecting them or a member of their household because of the epidemic, and poor people and those without college degrees are especially likely to have lost a job, according to a poll from The Associated Press-NORC Center for Public Affairs Research.

With over 240,000 people infected in the U.S. and the death toll topping 5,800, sobering preparations were under way. The Federal Emergency Management Agency asked the Pentagon for 100,000 body bags because of the possibility funeral homes will be overwhelmed, the military said.

Corpses in white plastic were already overwhelming the Daniel J. Schaefer Funeral Home in Sunset Park, Brooklyn, on Thursday. Usually equipped to handle 40-60 bodies at a time, it was taking care of 185. Masked workers fielded phone calls and handled file folders labeled "COVID-19" in yellow highlighter.

Owner Pat Marmo said he's been begging families to insist hospitals hold their dead loved ones as long as possible: "This is a state of emergency," he said. "We need help."

The Democratic Party pushed its nominating convention back a month, to mid-August. Federal authorities proposed a $611,000 fine against the Seattle-area nursing home connected to at least 40 coronavirus deaths, accusing it of infractions that included failure to report and rapidly manage the outbreak. And a days-long standoff in Florida was resolved when passengers aboard two cruise ships that have had several coronavirus cases and four deaths won permission to come ashore.

Elsewhere around the world, the number of people applying for welfare benefits in Britain increased nearly tenfold to almost 1 million in the past couple of weeks. At least a million in Europe are estimated to have lost their jobs over the same period, and the actual number is probably far higher. Spain alone added over 300,000 to its unemployment rolls in March.

But the job losses in Europe appear to be far smaller than in the U.S. because of countries' greater social safety nets.

With its health care system in dire shape, Spain reported a record one-day number of deaths, 950, bringing its overall toll to about 10,000, despite signs that the infection rate is slowing.

Italy recorded 760 more deaths, for a total of 13,900, the worst of any country, but new infections continued to level off.

France recorded a running total of about 4,500 deaths in hospitals, with 471 in the past day. But officials expect the overall toll to jump significantly because they are only now starting to count deaths in nursing homes and other facilities for older people.

White House coronavirus task force co-ordinator Dr. Deborah Birx said U.S. infection data suggest not enough Americans are heeding social distancing guidelines, and the country must do better in order to emulate those European nations that have begun "to bend their curves."

Gov. Andrew Cuomo warned that New York could run out of breathing machines in six days. He complained that states are competing against each other for protective gear and breathing machines, or are being outbid by the federal government, in a competition he likened to being on eBay.

In France, a top health official in the country's hard-hit eastern region said American officials swooped in at a Chinese airport to spirit away a planeload of masks that France had ordered.

Nine leading European university hospitals warned they will run out of essential medicines for COVID-19 patients in intensive care in less than two weeks.

A shipment of nearly 5,900 medical masks that Alabama's Montgomery County received from the U.S. government stockpile was unusable because of dry rot, the emergency management director said. The masks had a 2010 expiration date, according to the city of Montgomery.

The Trump administration was formalizing new guidance to recommend Americans wear coverings such as non-medical masks, T-shirts or bandannas over their mouths and noses when out in public, while reserving medical-grade masks, particularly the short-in-supply N95 variety, for those dealing directly with the sick.

Trump invoked the Defence Production Act on Thursday in hopes of boosting production of medical-grade masks by Minnesota-based 3M to assist first responders.

Washington is also trying to crack down on a growing black market for protective medical supplies, Defence Production Act policy co-ordinator Peter Navarro said.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough. But for others, especially older adults and people with health problems, it can cause severe symptoms like pneumonia. Over 200,000 people worldwide have recovered, by Johns Hopkins' count.

With large portions of America under lockdown, job losses for the world's biggest economy could double to 20 million and unemployment could spike to as high as 15% by the end of the month, many economists have said. Unemployment in the U.S. hasn't been that high since the tail end of the Depression, just before the U.S. entered World War II.

Roughly 90% of the U.S. population is now under stay-at-home orders, and many factories, restaurants, stores and other businesses are closed or have seen sales shrivel.

Laid-off workers can tap money made available in the $2.2 trillion rescue measure passed by Congress. It adds $600 a week to unemployment benefits, extends eligibility to 39 weeks and for the first time wraps in part-timers and workers in the so-called gig economy, such as Uber drivers.

Achsa Febrero, a Subway worker at a rest stop Fairfield, Conn., is among the millions laid off and now waiting for unemployment benefits to kick in, which could take weeks. She said she is on a payment plan to keep her phone connected and unsure how she'll pay for groceries -- and deeply frustrated at the billions benefiting corporations in the federal bailout.

"These companies are getting government relief, government relief," Febrero said. "They could afford to pay us more than what we're getting. They could support us through this time, and they're not. We're human. What makes them better than us?"
