U.S. coronavirus infections surged to top the world amid warnings that the pandemic is accelerating in cities like New York, Chicago and Detroit.

The U.S. now has more than 93,000 confirmed cases, surpassing China's 81,782 infections. New York state, the epicenter of the U.S. outbreak, reported 100 more deaths in one day, accounting for almost 30% of the more than 1,400 fatalities nationwide as doctors and nurses have spoken out about the dire risks they face.

Meanwhile, Congress worked to address the growing economic congress by passing a $2 trillion stimulus bill, and President Donald Trump implemented the Defense Production Act to force General Motors to produce ventilators prior to signing the CARES Act.

Here's the latest developments in the coronavirus crisis in the U.S.:

US First Country to Reach 100K Confirmed Coronavirus Cases

The United States has become the first country to exceed 100,000 confirmed cases of the new coronavirus.

The U.S. reached the grim milestone late Friday afternoon, according to a count by Johns Hopkins University. Deaths in the U.S. topped 1,500 on Friday.

Globally, the count of people with the virus was nearing 600,000.

President Trump Implements Defense Production Act

President Donald Trump implemented the Defense Production Act, meaning the federal government can require private businesses to accept contracts to produce items needed in a time of war/crisis. In this case, Trump said he would have General Motors produce ventilators to be used by hospitals treating COVID-19 patients.

"Our negotiations with GM regarding its ability to supply ventilators have been productive, but our fight against the virus is too urgent to allow the give-and-take of the contracting process to continue to run its normal course," Trump said in a statement. "GM was wasting time. Today’s action will help ensure the quick production of ventilators that will save American lives."

Some, including New York Gov. Andrew Cuomo, have urged Trump to implement the Defense Production Act earlier. Until now, Trump said he believed the private sector could fill the gap and provide needed equipment.

“It can’t just be, ‘Hey who wants to help? Let me know,’” Cuomo said on Monday. “We need to know the numbers of what we need to produce and who is going to produce that and when.”

New York Governor Andrew Cuomo made an emotional speech to the National Guard on Friday, thanking them for converting the Jacob K. Javits Center in Manhattan into a hospital.

Trump Signs Stimulus Bill: The CARES Act

The House approved a $2.2 trillion emergency package to help millions of newly unemployed Americans and struggling companies. President Donald Trump later signed it into law.

The House approved the sweeping measure by a voice vote, as strong majorities of both parties lined up behind the most colossal economic relief bill in the nation's history.

It will ship payments of up to $1,200 to millions of Americans, bolster unemployment benefits, and offer loans, grants and tax breaks to businesses large and small.

“Today we've all acknowledged our nation faces an economic and health emergency of historic proportions,” said House Speaker Nancy Pelosi.

NY Coronavirus Cases Soar to Nearly 45K, 500 Deaths

The number of coronavirus cases in New York has soared to nearly 45,000 with deaths surpassing 500 by Friday morning, NBC New York reports.

Gov. Andrew Cuomo announced during his daily briefing that there are more than 6,000 hospitalized COVID-19 patients in New York, with almost 1,600 in intensive care.

New York City has shouldered the brunt of the impact, with over 25,300 cases across the five boroughs. Most of the patients are younger than 50 -- and 20 percent of NYC cases have been hospitalized.

"This doesn't attack the strong among us. It attacks the weak among us, the people we're supposed to protect," Cuomo said Friday. "These are our parents, our aunts and uncles, a relative who is sick. Every instinct says protect them, they need us. But those are the exact people this enemy attacks."

Cuomo said the state wants to build four more temporary hospitals in New York City within weeks, before coronavirus cases are projected to peak. The federal government is already constructing a hospital at a Manhattan convention center and a Navy hospital ship is due to arrive Monday in New York City, a global hotspot of the outbreak.

New York Governor Andrew Cuomo made an emotional speech to the National Guard on Friday, thanking them for converting the Jacob K. Javits Center in Manhattan into a hospital.

Navy Hospital Ship USNS Mercy Arrives in Los Angeles

The USNS Mercy, a Navy hospital ship, arrived in Los Angeles Friday morning bringing much needed relief to Southern California's, NBC Los Angeles reports.

The Mercy set sail from San Diego on Monday and pulled into the Port of Los Angeles just after 11 a.m. ET. The one-time oil tanker was converted into a floating 1,000-bed hospital and will treat Non-COVID-19 patients in order to free up space in land-based hospital.

In Los Angeles County, the number of cases grew to 1,216 Thursday, including 21 people who have died, the LA County Department of Health said. There had been 559 new cases confirmed in the past 48 hours, and the department said the large increase was in part due to greater testing capacity that is allowing officials to identify cases.

President Donald Trump announced two naval hospital ships would be mobilized to help battle the coronavirus pandemic.

NYC Doctors Says COVID-19 Patients 'Are Dying Alone'

As an emergency medicine physician in New York City, Dr. Kamini Doobay has always known that death is part of the territory when trying to care for the city's sickest.

But it hasn't always been like this — patients hit the hardest by the coronavirus, struggling to breathe and on ventilators, with no visitors allowed because of strict protocols to prevent spreading the virus.

“So often a patient will be on their deathbed, dying alone, and it’s been incredibly painful to see the suffering of family members who I call from the ICU, hearing the tears, crying with them on the phone," said Doobay, 31.

“Too many people are dying alone with absolutely no family around them," she said. “This is one of the most horrific things."

Southwest to Cancel 1,500 Daily Flights

Southwest Airlines will cancel 1,500 daily flights starting Friday as demand for air travel continues to plummet amid the coronavirus outbreak.

NYC Mayor on Crisis at NYC Hospitals: Help With Supplies 'Has to Keep Coming'

New York City Mayor Bill de Blasio renewed his call for help from the federal government Friday as COVID-19 cases strained the city's hospital system.

“When the president says the state of New York doesn’t need 30,000 ventilators, with all due respect to him, he’s not looking at the facts of this astronomical growth of this crisis,” de Blasio said on ABC's “Good Morning America.”

De Blasio spoke in response to comments President Donald Trump made Thursday when he told Fox's Sean Hannity, “I don't believe you need 40,000 or 30,000 ventilators. You go into major hospitals sometimes, and they’ll have two ventilators. And now all of a sudden they’re saying, ‘Can we order 30,000 ventilators?’”

Asked how many of the ventilators that can keep critically ill coronavirus patients alive the city has on hand, de Blasio said the city has received about 2,500 in the last week or so.

“The state needs 30,000, the city needs 15,000,” he said. “So we’ve gotten something. I’m thankful for that," the Democratic mayor said. “But it has to keep coming."

“This is going to get worse before it gets better,” de Blasio added.

Trump Has 'Very Good Conversation' With China's President Xi

Trump tweeted early Friday saying he had a "very good conversation" with China's President Xi Jinping about the virus. He added that the two countries are committed to working together amid the pandemic.

Just finished a very good conversation with President Xi of China. Discussed in great detail the CoronaVirus that is ravaging large parts of our Planet. China has been through much & has developed a strong understanding of the Virus. We are working closely together. Much respect! — Donald J. Trump (@realDonaldTrump) March 27, 2020

Trump has been criticized in recent weeks for calling the coronavirus, which originated in Wuhan, China, the "Chinese virus." However, he seemed to back off from the term this week, NBC News reports. Trump was asked about the change in language Thursday and said that the virus did come from China but "I think it was time" and that "I don't have to say it, if they feel so strongly about it."
