7:40 pm: FDA 'aggressively monitoring' at-home tests

The U.S. Food and Drug Administration says it is "aggressively monitoring" at-home tests that claim to diagnose the coronavirus after seeing a slew of start-ups market kits that can be self-administered. The agency noted that some of these tests are unauthorized, going so far as to describe them as "fraudulent." Companies including Forward, EverlyWell and Carbon Health were offering at-home tests, but are now working with the F.D.A. to get clearance before sending them to homes, according to the Wall Street Journal. —Christina Farr

7:02 pm: Trump approval rating rises as he responds to the coronavirus outbreak

Crises are often the ticket to higher approval ratings for politicians, and President Donald Trump, it appears, is no exception.

During an election year, any bump could have significant ramifications.

In the latest Gallup poll, released Tuesday, Trump's approval rating hit 49%, matching his best performance in the poll.

Earlier this month, Trump's approval rating was at 44%, according to Gallup. The 5-point boost comes amid the president's near-daily participation in coronavirus task force briefings and series of moves to combat the pandemic in the United States. —Yelena Dzhanova

Nike executives during a post-earnings conference call Tuesday offered some encouraging words for the retail industry. CEO John Donahoe said he has confidence that everyone will see the "other side of this crisis in the near future."

Nike said it is starting to see a "recovery" in China, where the virus originated.

The company said that at a peak in February, roughly 75% of Nike stores in Greater China were closed, with others open on reduced hours. As of Tuesday, however, nearly 80% of its stores in Greater China are open, Nike said. And it added that digital sales in China are approaching triple-digit growth.

Donahoe said Nike will use this "playbook" from China to get other regions, like the U.S., back up and running again. — Lauren Thomas

6:32 pm: Does Tuesday's huge rebound mark the bottom for markets?

In market terms, think of the coronavirus sell-off as a three-legged stool where if one of the legs isn't firmly attached, the whole thing will tip over.

The first leg is monetary policy, and that comes in the form of rock-bottom interest rates and a slew of programs aimed at keeping the markets functioning properly and funneling money to businesses and individuals who need it. That is well in place thanks to the Federal Reserve over the course of the last two weeks.

The second is fiscal policy, or the dollars that will be directed specifically to needy areas, the unemployed and businesses that have been displaced by the way the coronavirus has seized the national economy and brought key industries to a virtual standstill. There finally are signs that this leg soon will be nailed down.

The final, and most important, part of the stool, though, remains in the workshop. That's some kind of assurance that the virus has been contained, that the caseload and mortality rate at least plateaus and gives an indication that some sense of normalcy can be restored. —Jeff Cox

6:23 pm: White House official tells anyone who has left NYC that they should self-quarantine

Members of the White House coronavirus task force urged those leaving New York City to self-quarantine for 14-days in order to stop the spread of COVID-19 during a press briefing on Tuesday.

6:07 pm: Amazon has been the king of big tech stocks during the coronavirus sell-off

During the past month's extreme market volatility, Amazon has been a relative safe haven.

And that tells you everything you need to know about the company's critical role in society. 

Even with the economy almost certainly headed into recession and unemployment projected to spike, consumers are flocking to Amazon to buy essential health and household products while getting groceries delivered through services like Amazon Fresh. Last week, Amazon said that it's hiring an additional 100,000 full-time and part-time employees in the U.S. for warehouse and delivery jobs to meet the surge in demand from online shopping amid the coronavirus outbreak, and is increasing pay and offering more lenient sick leave policies to keep workers engaged. —Ari Levy

New York Gov. Andrew Cuomo announced Monday that the state's health department would begin using the plasma treatment on critically ill coronavirus patients.Known as convalescent plasma, the treatment is centuries-old and was used during the 1918 flu pandemic. It involves harvesting antibodies that fight viruses from the blood of those who were previously infected. The method was also used on some patients during the 2002 SARS outbreak.The FDA cautioned that convalescent plasma has not yet been proven effective for the coronavirus and that researchers should apply for permission before beginning a trial that uses it. —Hannah Miller

1:18 pm: Mortgage closings at risk as coronavirus shutters title and recording offices

Not even a month ago, thousands of borrowers were rushing to take advantage of record-low mortgage rates. Refinance applications soared over 400% annually, and homebuyers were out early and in force.

But now some of those loans are stuck in limbo as the in-person closing process can no longer be held.

Across the nation, state, county and local governments, including recording offices, have shut down or are at least limiting the number of people who may enter the office.

That puts the whole system at risk, as title insurers are less able to conduct the title research that goes into issuing a policy. The ability to record documents is also getting tougher as county recording offices close. —Diana Olick

NY Gov. Cuomo on Trump and coronavirus: No American will say speed up economy at the cost of lives
NY Gov. Cuomo on Trump and coronavirus: Don't speed up economy at cost of life

New York Gov. Andrew Cuomo pushed back hard against the idea raised by President Donald Trump of easing restrictions from coronavirus mitigation efforts in an effort to revive the U.S. economy.

"I understand what the president is saying that this is unsustainable that we close down the economy and we continue to spend money. There is no doubt about that," Cuomo said at a press conference in New York City.

"But if you ask the American people to choose between public health and the economy then it's no contest. No American is going to say 'accelerate the economy at the cost of human life,'" Cuomo argued. —Dan Mangan

A total of 13 states so far have orders to stay at home, including California, New York, Washington State and Illinois. Three states have advisories or instructions from their governors to remain at home. Four states have either cities or counties with stay-at-home orders. —Hannah Miller

12:55 pm: You can now pause payments on your federal student loans for 2 months. Here's what experts say to keep in mind

Borrowers with federal student loans now have two options for relief if they suffer financial hardship from the coronavirus pandemic.

The Department of Education announced that all borrowers with federal loans will have their interest rates automatically set at 0% for at least 60 days, a measure first announced by President Donald Trump earlier this month. Now, borrowers with federal loans have the option to suspend payments completely for at least two months without accruing interest.

While the interest rate reduction is automatic, borrowers need to request the suspension of payment, called a forbearance, from their loan servicers online or by phone. This can help free up cash for other bills or financial obligations during the coronavirus crisis. —Alicia Adamczyk

Microsoft CEO Satya Nadella said that the hardware supply chain is coming back online as the coronavirus outbreak eases up in Asia, but said that the big question would be whether demand holds up in the U.S. and Europe.

"On the supply side we are getting back on rails," Nadella told CNBC's Jon Fortt when asked about whether Microsoft would be able to deliver later this year certain products it had promised before COVID-19 took hold, like new Surface devices and a revamped Xbox gaming console.

"We have a great balance sheet, we are a very diverse business, we have a mix of annuity, non-annuity, that is also stronger than even the last time we even went into the financial crisis," he said. "I feel confident we'll come out of this, frankly, pretty strong."

He said the company's cloud infrastructure and services have been holding up under increased demand. —Jordan Novet

Johnson said Starbucks built a model to follow the company's business recovery in China, where the coronavirus pandemic began in late December. "It's now like week three here in the U.S. and we look back at what happened in China and we sort of know what to expect," Johnson said. —Kevin Stankiewicz

Macy's, J.C. Penney, Nordstrom and Kohl's have closed their shops across the U.S. temporarily, to try to help halt the spread of COVID-19. Many specialty shops found in the mall, such as American Eagle and Gap, have also closed up. Some mall owners, including the biggest in the U.S., Simon Property Group, have shut all of their properties for the time being. 

But there is still at least one department store chain keeping its doors open: Dillard's.

CNBC spoke to multiple employees, one of which said they were "begging" for the company to close. The workers all requested anonymity to protect their jobs. —Lauren Thomas

"Our people want to return to work," Trump tweeted. "They will practice Social Distancing and all else, and Seniors will be watched over protectively & lovingly. We can do two things together."

Kudlow, the director of the National Economic Council, echoed Trump's remarks from a Monday evening press briefing that some states with low numbers of confirmed cases might be able to ease off their restrictions quickly. That relief could come soon after the White House's 15-day guidelines on social distancing expire next week, Kudlow said. —Kevin Breuninger

The FEMA chief added that the White House will add "DPA language" into its mass contract for 500 million masks. —Thomas Franck

11:08 am: Total number of Italian coronavirus cases could be '10 times higher' than known tally, according to one official

The number of coronavirus cases in Italy is probably 10 times higher than the official tally, the head of the agency collating the data said as the government readied new measures to force people to stay at home.

"A ratio of one certified case out of every 10 is credible," Angelo Borrelli, the head of the Civil Protection Agency, told La Repubblica newspaper, indicating he believed as many as 640,000 people could have been infected.

Italy has seen more fatalities than any other country, with latest figures showing that 6,077 people have died from the infection in barely a month, while the number of confirmed cases has hit 64,000. However, testing for the disease has often been limited to people seeking hospital care, meaning that thousands of infections have certainly gone undetected. —Reuters

Two of the largest private labs in the U.S. will collectively be able to process more than 300,000 COVID-19 tests by the end of the week, their CEOs say. LabCorp CEO Adam Schechter told CNBC's "Squawk Box" the company is processing around 20,000 tests daily and will by the end of the week be able to "a lot more" than 100,000 tests per week. 

Quest Diagnostics is conducting about 25,000 COVID-19 tests per day, with plans of increasing daily capacity to around 30,000 by the end of the week, CEO Steve Rusckowski told CNBC's "Closing Bell." That would put Quest's weekly capacity around 200,000, he said. —Kevin Stankiewicz

The International Olympic Committee postponed the 2020 Olympic and Paralympic Games, officials announced Tuesday. The event was scheduled to start July 24 in Tokyo.

Japanese Prime Minister Shinzo Abe said he and the head of the IOC agreed to delay the 2020 Olympics in Tokyo for about a year. The games will take place "no later than summer 2021," according to a statement from the IOC.

Abe was speaking to reporters after a phone call with IOC President Thomas Bach on postponing the Games amid growing concerns over the coronavirus pandemic.

Italy's death toll rose by 602, the smallest increase in four days, according to Reuters. The number of new confirmed cases also slowed.

Conte stepped up the national lockdown measures over the weekend, ordering the closure of all industrial production and almost all private and public offices. However, metalworkers and bank unions vowed to strike this week. They are demanding more stringent measures for the factories that are still open and for bank employees, who they say do not have enough masks, gloves or disinfectant. —Silvia Amaro
