President Donald Trump said he will be meeting with Senate and House Republicans on Tuesday to discuss a possible tax relief measure to provide "a timely and effective response to the coronavirus."

"We are to be meeting with House Republicans, Mitch McConnell, and discussing a possible payroll tax cut or relief, substantial relief, very substantial relief," Trump said at a press briefing with coronavirus task force members.

"It's a big number," he added. "We're also going to be talking about hourly wage earners getting help so they can be in a position where they're not going to miss a paycheck."

A Walmart employee who works at a Kentucky store has been diagnosed with coronavirus, the company confirmed to CNBC. The employee worked at a store in Cynthiana, which is about 30 miles northeast of Lexington. Walmart said in a statement that it "reinforced our cleaning and sanitizing protocols" and consulted with health experts before deciding to keep the store open. The company said it has encouraged employees to stay at home or go to the doctor if they do not feel well. "Rest assured, we will continue to take any and all measures necessary to ensure the well-being of our associates and customers," the statement said.
 
The Walmart employee was Kentucky's first resident to test positive for the coronavirus, according to state officials. At a news conference Monday, they said six coworkers have isolated themselves and have not shown symptoms. Kentucky Governor Andy Beshear acknowledged the anxiety around the coronavirus. "For everybody who has been through that Walmart, I know it's going to make you nervous," he said during a news conference. "Just because you've been there doesn't mean that you have the coronavirus. We have to stay calm."—Repko

Correction: This item was revised to correct that Cynthiana is northeast of Lexington.

New Jersey Governor Phil Murphy declared a state of emergency and a public health emergency to free up state funds for districts across the state. The announcement comes as the number of COVID-19 cases in the tri-state area tripled to at least 155, up from 49 confirmed cases on Friday. —Feuer

Tesla shares plummeted by 13.6% to $608 per share on Monday, dropping 6 percentage points more than the S&P for the day, as plunging oil prices and the continuing coronavirus outbreak weighed on investors.

The oil price battles between Saudi Arabia and Russia could challenge Tesla's electric vehicle and solar roof sales in markets where it remains more affordable for people to stick with fossil fuels, and where they are not incentivized to switch to renewables. Historically, when crude oil and gas prices decline, electric vehicle sales -- and solar installations -- slow down.

Tesla is also grappling with the impact of the novel coronavirus outbreak in and beyond China. The epidemic has forced temporary closures of Tesla's new Shanghai car plant and stores throughout the country. —Kolodny

President Donald Trump had contact with two Republican congressmen before their announcements Monday that they were entering self-quarantine after learning they had been previously exposed to someone since diagnosed with coronavirus.

Rep. Doug Collins of Georgia shook hands with Trump last Friday when the president traveled to Atlanta to visit the Centers for Disease Control and Prevention, where officials there briefed him on their response to coronavirus.

Rep. Matt Gaetz of Florida flew on Air Force One with Trump on Monday on a flight from Orlando, Fla., to Joint Base Andrews in Maryland. The New York Times, citing two people with knowledge of the situation, reported that Gaetz learned shortly after the plane was airborne that he, like Collins, had been in contact with a person at the Conservative Political Action Conference in Maryland in late February who since has been diagnosed with coronavirus. Gaetz then sat in a section of the plane by himself, the newspaper reported.

Gaetz publicly revealed he was entering self-quarantining about an hour after he got off the plane with Trump.

Video footage shows Gaetz on the tarmac at Joint Base Andrews stepping backwards and raising his hand as if to keep a man approaching at a distance from him. —Breuninger

Health insurer giant Anthem told CNBC that it's telling all of its New York City employees to work from home out of an "abundance of caution." The move came after "coronavirus-related" developments in the city, a spokesperson said. Earlier in the day, New York City Mayor Bill de Blasio urged people to work from home as COVID-19 continues to spread across the U.S. and the death toll continues to rise. —Lovelace

Italian Prime Minister Giuseppe Conte said Monday he will sign a decree that extends the lock down of the Lombardy region to the entire country as Italy's COVID-19 death toll continues to rise.

People throughout the country should not leave their homes other than for work and emergencies, Conte said. He added that all public gatherings will be banned and sporting events suspended.

Italian officials previously announced a lock down of the Lombardy region, which is the hardest-hit part of the country by COVID-19.

The new coronavirus has infected more than 9,172 across Italy, according to Johns Hopkins University, killing at least 463. —Feuer

It takes an average of about five days for COVID-19 symptoms to show after contracting the virus, while the vast majority of people infected will develop symptoms within 12 days, researchers confirmed in a new report published in the "Annals of Internal Medicine" on Monday.

The American College of Physicians said 97.5% of people infected with the new coronavirus will show symptoms within twelve days of catching the virus. The average incubation time is five days, researchers said. That's in line with current Centers for Disease Control and Prevention recommendations that call for patients to remain in quarantine or self-isolation for 14 days after potential exposure.

Researchers from Johns Hopkins Bloomberg School of Public Health analyzed reports from 50 provinces, regions and countries outside of Wuhan, China, to determine the virus's incubation period. Researchers found 181 confirmed cases with timeframes for identifiable exposure and symptom onset. —Bursztynsky

Faced with a growing economic threat from the coronavirus spread, regulators on Monday urged banks to make sure "customers and members" impacted by the disease get the funding they need.

In a joint statement issued after the market close Monday, multiple agencies said they will work with banks to "provide appropriate regulatory assistance" to financial institutions under their supervision in meeting financial needs.

The statement comes amid steep losses in the stock market, with particular pressure on energy and banks. The signers included the FDIC, Consumer Financial Protection Bureau, the Conference of Bank State Supervisors, the Federal Reserve, National Credit Union Administration and Office of the Comptroller of the Currency. —Cox

Facing a wave of pressure from workers and increased scrutiny from lawmakers on Capitol Hill, gig economy companies from Uber to Doordash have been rolling out a slate of new policies as coronavirus continues to spread across the U.S.

Uber and Lyft are planning to compensate drivers affected by the coronavirus for up to 14 days. Postmates and Instacart have unveiled "no-contact" food delivery. DoorDash, meanwhile, is letting customers leave in-app instructions if they prefer orders left at the door.

But some workers on these platforms are balking at these steps, saying they still don't go far enough and details are scarce. Amazon Flex, which taps independent contractors to make deliveries, doesn't have a policy to compensate drivers and is instead supporting on an "individual, case-by-case basis."—Bosa

A woman in her 60s died at El Camino Hospital of COVID-19, the Santa Clara County Public Health Department said in a statement. She was the first instance of community transmission in the county, local officials said, and she had been hospitalized for several weeks. "We are facing a historic public health challenge and know this is a very difficult time. Our top priority continues to be protecting the health of our community," health officer for Santa Clara County Dr. Sara Cody said. —Feuer

Seattle and King County officials reported 33 new cases, including two deaths, and said that one person who was previously reported as a positive case has died. That brings the total number of cases in the county to 116 and 20 deaths, 19 of which are all connected to the Life Care residential home in Kirkland.

Local officials said that all residents of Life Care have now been tested and results are pending. Health officials said they plan to test all employees of the facility, but have not yet. Local officials also said that testing capacity is still limited. "While testing is becoming more available, there are limitations in providers' capacity to obtain samples and process lab results rapidly," the county said in a statement. —Feuer

Google is restricting all visitors from its headquarters in Mountain View and other offices in the San Francisco Bay Area and New York as the COVID-19 coronavirus spreads, a spokesperson confirmed to CNBC on Monday.

The company is also taking other steps, including recommending that employees in Japan and South Korea work from home, permitting employees in other locations to work remotely, and canceling all in-person job interviews for the "foreseeable future" to "protect our candidates' and interviewers' health and well-being."

The spokesperson added that as the COVID-19 situation changes, its "rule of thumb" for individual offices comes from regional health guidance from the CDC and WHO. The latest measures come amid Alphabet's attempts to mobilize its workforce of more than 300,000 workers to deal with the crisis. Alphabet's top executives including CEO Sundar Pichai and CFO Ruth Porat urged employees to stay motivated to run Google's global infrastructure amid sweeping changes and fears around the virus spread, CNBC reported last week. —Elias

Amazon is asking employees at its New York and New Jersey offices to work from home if they can until the end of the month. 

The company informed employees of the change on Monday. The Amazon-owned audiobook company, Audible, is headquartered in Newark, New Jersey. Amazon also employs thousands of people in New York City, including employees at Amazon Web Services and members of sales and marketing teams, among other units.

Last week, Amazon told employees at its offices in the San Francisco Bay Area and the Seattle area to work from home if they can until the end of the month. The announcement came after an employee in one of its Seattle offices tested positive for COVID-19. —Palmer

New York Mayor Bill de Blasio on Monday urged people to work from home as the coronavirus continues to spread across the U.S. and the death toll continues to rise. 

"For a business that can allow more employees to telecommute, we want you to do that," he said in a press briefing. "We simply want to reduce the number of people on mass transit just to open up some more space."

"The challenge," he continued, "is people just packed like sardines" in New York City, where he said it can be much easier to transmit disease among tight crowds. —Dzhanova

Iraq has banned all public gatherings and called on citizens to avoid visiting sacred cities and sites to stop the spread of the coronavirus, an official statement said on Monday.

The death toll from an outbreak of coronavirus in Italy has risen by 97 to 463, the Civil Protection Agency said on Monday, a slower rate of increase than registered the day before.

The total number of cases in Italy, the European country hardest hit by the virus in Europe, rose 24% to 9,172, the largest daily increase in terms of absolute numbers since the contagion first came to light on Feb. 21.

The head of the agency said that, of those originally infected, 724 had fully recovered, compared to 622 the day before. Some 733 people were in intensive care against a previous 650. —Reuters

One-way tickets for some domestic routes dropped below $50 for the coming weeks, more evidence of falling demand for air travel as coronavirus spreads within the U.S. Companies are canceling business trips and leisure travelers are rethinking vacations, keeping a lid on airfares and presenting airlines with more trauma as they grapple with the biggest crisis since 9/11.

The timing couldn't be worse with the peak spring and summer travel seasons, the most lucrative for airlines, approach. Airline bookings in North America were down about 8% in the last week of February and by "mid-teen" percentage points in the first week of March, according to a Credit Suisse note published Monday. —Josephs

The CDC  has 75,000 lab kits "cumulatively" for public labs to test for COVID-19 with more coming on board soon, Dr. Nancy Messonnier, director of the CDC's National Center for Immunization and Respiratory Diseases, said during a conference call. —Higgins-Dunn

Apple has updated its website with instructions that say it's OK to use disinfectant wipes to clean your iPhone and other Apple gadgets.

Previously, Apple's site advised against using cleaning products because they can sometimes damage the special coating on screens that helps prevent fingerprints.

″Using a 70 percent isopropyl alcohol wipe or Clorox disinfecting wipes, you may gently wipe the hard, nonporous surfaces of your Apple product, such as the display, keyboard, or other exterior surfaces," Apple's site now says. "Don't use bleach. Avoid getting moisture in any opening, and don't submerge your Apple product in any cleaning agents. Don't use on fabric or leather surfaces." —Haselton

There are differences in what coronavirus-related costs may be incurred by patients depending on the type of their plan, its coverage and insurance carrier. Here are some expenses to consider:

• Copays and cost-sharing may be waived in some cases for COVID-19 testing, but not necessarily for all tests, treatments, office visits or other medical care related to your illness.
• Before your medical coverage kicks in, depending on your plan, you may have to face copays, coinsurance — and your deductible.
• If you're self-quarantined at home, your plan should cover any doctors visits if you go out and medical care by a licensed professional if you stay in. 
• Your portion of all these costs can add up quickly, so it's a good idea to have some money saved. —Epperson

CNBC's Jim Cramer said hedge fund legend David Tepper is worried about the economic fallout from the coronavirus. "I spoke to David this morning and yesterday, and it is the 'game changer' make no mistake about it," Cramer said on "Squawk on the Street." "He's very, very concerned."

Cramer's reference to "game changer" is a call back to what the Appaloosa Management founder told him in an interview last month at the Super Bowl in Miami for TheStreet. The coronavirus has "certainly ruined the environment" for stocks that had been the case before the outbreak, Tepper told Cramer on the red carpet for 9th Annual NFL Honors show, one day before the big game on Feb. 2.

"You have to be careful, because it may be a game changer. So you've just got to be cautious," Tepper said at the time. Besides his investing interests, Tepper owns the NFL's Carolina Panthers. —Belvedere

The threat of a global pandemic is rising as the new coronavirus rapidly spreads across the world from Asia, to Europe, the Middle East, and now parts of the United States, World Health Organization officials said.

"Now that the virus has a foothold in so many countries, the threat of a pandemic has become very real," WHO Director-General Dr. Tedros Adhanom Ghebreyesus told reporters on a conference call from the organization's Geneva headquarters Monday. 

WHO officials stopped just short of calling a global pandemic, indicating that they are getting closer to making the declaration — even as China and Singapore appear to have successfully contained the spread in their countries. "When you reach 100 countries and when you reach 100,000 cases, it is time to step back and think, two weeks ago it was 30 countries," said Dr. Mike Ryan, the executive director of the WHO's emergencies program. —Feuer

Concerns over coronavirus have roiled markets and torched hundreds of billions in paper wealth from the world's billionaires over the past month. Amazon chief Jeff Bezos lost $7 billion in paper wealth overnight, and more than $18 billion over the past month. Tesla CEO Elon Musk, who tweeted that the "coronavirus panic is dumb," has seen about $4 billion of his paper wealth lopped off overnight. That would bring his losses for the month down to more than $12 billion. Perhaps the biggest billionaire loser from the virus, however, is LVMH chief Bernard Arnault. His losses bump him back down to the second richest man, behind Bill Gates. —Frank

A New York federal court district is barring from its courthouses any people who have been to five countries — China, South Korea, Japan, Italy, and Iran — within the past two weeks because of coronavirus concerns. The ban announced Monday applies to courthouses in the Southern District of New York, which are located in downtown Manhattan, and in the cities of White Plains and Poughkeepsie.

The Southern District handles federal criminal, civil and bankruptcy cases from Manhattan and the Bronx boroughs in New York City, as well as from the counties of Westchester, Putnam, Orange, Dutchess, and Sullivan. The ban also applies to people who reside in or who have had close contact with someone who has been in one of the five countries in the past 14 days, people who have been asked to self-quarantine by health workers, and people who have been diagnosed with or been in contact with people who have been diagnosed with coronavirus, also known as COVID-19. —Mangan

Thousands of passengers on a third Princess Cruises ship are being kept on board while crew members get tested for COVID-19. The Caribbean Princess, on a 10-day trip to the Panama Canal, was scheduled to dock in Grand Cayman on Monday. But the Çalifornia-based cruise line said it will keep passengers and crew from disembarking, and instead will pick up test kits after notifying the CDC that two crew members had transferred from a Princess ship in California where a guest had tested positive for COVID-19. These crew members being tested are currently "asymptomatic" and are remaining alone in their rooms "out of an abundance of caution" as the ship returns to Fort Lauderdale, the company statement said. The ship is under a "no sail order" from the U.S Centers for Disease Control and Prevention, which will require it to remain at anchor off the coast of Florida until further notice, the statement said. It was originally scheduled to return to Fort Lauderdale on Wednesday. —Associated Press

Germany confirmed its first two deaths from the coronavirus. A spokesman for the health ministry in the western state of North Rhine-Westphalia said an 89-year-old woman with coronavirus had died in the town of Essen and that another patient had died in the badly affected region of Heinsberg. Germany has so far reported 1,112 cases of the coronavirus, with the large state of North Rhine-Westphalia the most affected region. Several hundred cases have also been reported in the southern states of Bavaria and Baden-Wuerttemberg. The patient in Essen had tested positive with coronavirus on March 3 after being hospitalized in an already critical condition, local authorities said. The woman's state of health deteriorated further in the following days and she then died of pneumonia caused by her infection with the coronavirus, they said. The town of Heinsberg said in a statement it would hold a news conference on the second death case later on Monday. —Reuters

Cyprus reported its first two confirmed cases of coronavirus, including a public health professional who had contact with medical patients before he reported his symptoms to authorities. Both patients — males — had traveled from abroad. The first case involved a 25-year-old man who had returned from northern Italy and the second, the health professional, a 64-year-old who returned from Britain on March 3. Health Minister Constantinos Ioannou said it was "regrettable" that the second patient, who developed symptoms on March 3, only reported to authorities on Sunday. "This does complicate efforts by the ministry on the tracing we need to do on the contacts he had over the past five days," he said. The health professional works at a public health facility in the capital Nicosia. —Reuters

New York Gov. Andrew Cuomo said Rick Cotton, the Port Authority's executive director for New York and New Jersey, has tested positive for the new coronavirus. Cotton "is going to be on quarantine" and will be working at home, Cuomo said at a press briefing. The team of senior officials who work with Cotton will also be tested, Cuomo said. "Several of them may be on quarantine," he said. Cotton has been overseeing the arrival of overseas flights coming into airports in the area, including John F. Kennedy International Airport. —Breuninger

As fears about the coronavirus mount, so do concerns about possible quarantines, office closures, and school shutdowns. If you get paid time off from your employer or you can work from home, you shouldn't have much of a financial issue unless you use up all of your days. If you are sick, you could apply for short-term disability if you are out long enough. Some employers may already have an emergency leave policy, especially if they are used to dealing with things like snowstorms and hurricanes, said Rich Fuerstenberg, a senior partner at the consulting firm Mercer. Check with your employer, since that policy isn't a guarantee. The most important thing is to have an emergency fund so that you can help cover your expenses for the next month or so, especially if you aren't going to be getting paid. —Fox

New York Gov. Andrew Cuomo identified New Rochelle, a city in Westchester County where the first coronavirus patient in the state was found, as a "significant hot spot" in the state, which now has at least 106 confirmed cases. Cuomo said he's been in talks with officials from the Centers for Disease Control and Prevention about the outbreak in New York, particularly in New Rochelle. Schools might be closed "for a number of weeks" in the area and Cuomo said if a student tests positive going forward, that school will be closed "for an initial 24-hour period" while officials investigate. —Higgins-Dunn, Dzhanova

A U.S. Marine in the Washington D.C.-area who recently returned from official travel overseas has tested positive for the coronavirus, the Pentagon said on Saturday, in what would be the third confirmed case among U.S. servicemembers and the first in the U.S. The other two U.S. troops who have tested positive are a sailor in Italy and a soldier in South Korea. Pentagon spokesman Jonathan Hoffman said in a statement that the Marine was assigned to Fort Belvoir, Virginia, and was currently being treated at Fort Belvoir Community Hospital. Fort Belvoir is a major base in suburban Virginia, not far from the Pentagon. The U.S. military did not disclose the Marine's rank or say where the Marine had traveled. Hoffman said Defense Secretary Mark Esper and the White House had been briefed. A U.S. defense official, speaking on condition of anonymity, said the Marine was a man and that his family was now on a 14-day quarantine. The U.S. military was working with state and local officials to trace contacts that the Marine had in the area. It was unclear whether Fort Belvoir was taking any other precautionary measures. The base did not respond to a request for comment. —Reuters

President Donald Trump sought to downplay the plunging price of oil and the global spread of the new coronavirus as markets fell on Monday, saying that falling gas prices were good for consumers and comparing the coronavirus to the common flu. "Good for the consumer, gasoline prices coming down!" Trump wrote in one of a series of posts on Twitter. In another, he wrote that the flu killed 37,000 Americans last year, compared to 22 known deaths from COVID-19. "Nothing is shut down, life & the economy go on," he tweeted. Trump plans to meet with his economic team, including Treasury Secretary Steven Mnuchin, later in the day on financial proposals, including paid sick leave, to combat the economic fallout of coronavirus, Reuters reported. —Higgins, Cullen

Saudi Arabia closed off air and sea travel to nine countries affected by the new coronavirus as Mideast stock markets tumbled over fears about the widening outbreak's effect on the global economy. In the Mideast, there have been over 7,600 confirmed cases, with the vast majority in hard-hit Iran. The country's health ministry said the new coronavirus has killed another 43 people, pushing the death toll to 237 amid 7,161 confirmed cases. Experts worry Iran may be underreporting its cases. "Out of concern to protect the health of citizens and residents and ensure their safety, the kingdom's government decided to temporarily suspend the travel," it said in a statement attributed to an unnamed Interior Ministry official. Separately, Egypt's prime minister announced a temporary ban on large public gatherings and all events involving people's movement between cities. Abu Dhabi's long-haul carrier Etihad, which operated 12 flights daily to Saudi Arabia, said three flights had been airborne at the time of the announcement. When those planes landed in Dammam, Jiddah, and Riyadh, only Saudi citizens could disembark, with others having to return to Abu Dhabi, the airline said. —Associated Press

JetBlue Airways on Monday withdrew its first-quarter and full-year earnings forecast and said it was considering voluntary time-off programs for employees, as the coronavirus outbreak wreaks havoc on the global travel industry. JetBlue said it is adjusting schedules between March and early May due to falling demand, and is evaluating further flight cancellations as the situation around the epidemic develops. The company also said it was delaying some hiring and increasing the frequency with which it cleans aircraft. An industry body last week estimated the outbreak could lower passenger revenue globally for airlines by as much as $113 billion this year, as demand collapses. —Reuters

The president of Princeton University said the school will move to online courses following spring break and said it would begin the decrease the number of gatherings on campus in order to protect students and faculty from the spread of COVID-19.  "While much remains unknown about COVID-19's epidemiology and impact, our medical advisers tell us that we should proceed on the assumption that the virus will spread more broadly and eventually reach our campus," President Chris Eisgruber said in a statement. "They also tell us that the best time to put in place policies to slow the spread of the virus is now, before we begin to see cases on our campus, rather than later. Acting now will also give students who wish to do so the option to stay home after spring break and meet academic requirements remotely." To achieve its goal, the university will move activities such as lectures, seminars, and precepts, online. "We will continue to support, where possible and subject to appropriate restrictions, research, educational, and campus life activities that require physical presence," Eisgruber wrote. —Cullen 

The Food and Drug Administration and the Federal Trade Commission issued warning letters to televangelist Jim Bakker and six other companies for reportedly selling unapproved coronavirus drugs and treatment products. "The FDA considers the sale and promotion of fraudulent COVID-19 products to be a threat to the public health," FDA Commissioner Stephen M. Hahn said in the statement. The products include teas, essential oils, tinctures and colloidal silver, which had been previously cited as not safe or effective for treating any disease, according to a press release. —Higgins-Dunn

All schools in the northern Spanish city of Vitoria-Gasteiz will be closed for two weeks in an effort to slow the spread of coronavirus, regional authorities said on Monday. "All education activities are suspended in the city of Vitoria for two weeks...from kindergarten to universities," a spokesman for the education department of the Basque Country told Reuters. With nearly 150 confirmed cases the Basque Country, of which Vitoria is the regional capital, is among the worst-hit areas in Spain, which has registered 999 cases and more than 20 deaths from the outbreak. —Reuters

CNBC's Jim Cramer said financial turmoil from the coronavirus shows that monetary policy is no longer an appropriate solution. "This is just the need for fiscal policy," Cramer said on "Squawk on the Street." "Monetary policy is over." Last week, the Federal Reserve cut interest rates by a half percentage point in response to the growing economic threat from COVID-19. Cramer has been critical of that decision, arguing the government should actually be stepping up to provide financial help to small and medium-sized businesses who may see significant challenges from the disease's spread. Those businesses should have an opportunity to access zero-interest loans, for example, Cramer said Monday. —Stankiewicz

U.S. Health Secretary Alex Azar said President Donald Trump's administration is working aggressively on the coronavirus disease spreading worldwide after he was asked on a media conference call to respond to the stock market plunging on coronavirus fears.

"We're taking COVID-19 incredibly seriously," he also said, using the official name for the virus. —Reuters

Seattle-based Amazon and Redmond, Washington-based Microsoft said they were each contributing $1 million to the Seattle Foundation fund. The money will be used toward "resources to organizations in the Puget Sound region working with communities who are disproportionally impacted by coronavirus and the economic consequences of the outbreak," the company said. The fund currently has over $2.5 million, according to a statement from the nonprofit foundation. Amazon has been battling the coronavirus on several fronts. It recently said it's removing thosuands of high-priced items to prevent price gouging on its site. It asked employees in Seattle and Bellevue, Washington to work from home if they can through the rest of the month. And last week, an Amazon employee tested positive for coronavirus. At least 22 people have died from coronavirus in the US, including 19 in Washington where confirmed cases hit 136 people. "Funds will be released on a rolling basis as fundraising continues throughout the outbreak and recovery phases of the crisis, making it possible to move resources quickly and adapt to evolving needs in subsequent funding phases," the company said. —Haselton

U.S. stocks cratered at the market open as investors braced for the economic fallout from the spreading coronavirus, while a shocking all-out oil price war added to the anxiety. The Dow Jones Industrial Average tanked more than 1,900 points, while the S&P 500 plunged more than 7%. The massive sell-off triggered a key market circuit breaker in morning trading. Trading was halted for 15 minutes until reopening at 9:49 a.m. ET. Investors continued to seek safer assets amid additional fears that the coronavirus will disrupt global supply chains and tip the economy into a recession. The yield on the benchmark 10-year Treasury note dropped below 0.5% for the first time ever, while the 30-year rate breached 1%. —Li

The IMF's chief economist urged policymakers to implement "substantial" fiscal and monetary policies to help consumers and businesses cope with the economic harm of the coronavirus outbreak.

The U.S. will need a "massive financial package" to curb the spread of COVID-19, former Food and Drug Administration commissioner Scott Gottlieb told CNBC on Monday. The virus has spread past the point of containment, Gottlieb said, and hard-hit regions should be moving toward easing efforts such as school and business closures. He said a bailout now to encourage those steps would cost less than one after the outbreak spreads beyond control. "We're going to end up with a massive fiscal package, a bailout on the back end of this," he said on "Squawk Box." "We are better off using that money up front to help buy some of the actions that we need to mitigate this epidemic rather than spending that money on the back end after we've had a very large epidemic." —Feuer

The Regal Princess cruise ship finally pulled into a Florida port and passengers began disembarking after two crew members tested negative for coronavirus. The Regal Princess was originally to have docked Sunday morning in Port Everglades but spent most of the day sailing up and down the coast. The Coast Guard delivered testing kits to the Regal Princess, and the Centers for Disease Control and Prevention issued a "no-sail order" for the ship. The crew members in question had transferred more than two weeks ago from the Grand Princess cruise ship in California where nearly two dozen on board have tested positive for the virus, including 19 crew members, according to Princess Cruises. A Port of Everglades spokeswoman, Ellen Kennedy, said Sunday that the CDC had cleared the ship to enter port. She told The Associated Press by email that the ship would be docking at a cruise terminal in the port about 10 p.m. ET Sunday. A Princess Cruises statement issued early Monday said the CDC issued the clearance after the test results came back negative. After the ship docked, passengers stood on their balconies as they waited to disembark, the South Florida Sun Sentinel reported from scene. The first passengers were let off about an hour after the ship pulled into port. —Associated Press

Amazon is relaxing its attendance policy for warehouse workers and other employees due to the continued spread of coronavirus. The company informed employees Sunday that it will not count any unpaid time off should they need to take it during the month of March. Amazon told CNBC it made the change to ensure there are no repercussions for needing to stay home due to illness. The change of policy applies to employees whose job requires them to "work from an office, store, fulfillment center, delivery station or sort center," according to a document obtained by CNBC. Amazon also told employees it will not assign attendance points if they're unable to come to work. The company uses a point system to track employee infractions in a given period of time. —Palmer
