Zoom has enjoyed plenty of attention for outperforming market indices this year. That's because more people are using its videoconference software to meet with colleagues, clients and classmates as schools and businesses send employees home to duck the COVID-19 coronavirus.

You might not know know it, but legacy enterprise technology company Cisco is also seeing heavy-duty usage of its Zoom competitor, Webex, where Zoom CEO Eric Yuan was once vice president of engineering.

Cuomo said at least 264 New Yorkers, or 19% of the known cases, have been hospitalized with COVID-19. The number of New Yorkers hospitalized with the virus is higher than average, Cuomo said during a press briefing on the COVID-19 outbreak spreading throughout the state.

The Federal Reserve is continuing to provide support for short-term bank funding, as it will institute another $500 billion repo operation Tuesday afternoon amid intensifying funding pressures.

In the latest operation, the Fed will conduct another operation that comes on top of a similar offering Monday. The central bank's New York trading desk has been aiming to quell disruptions in the overnight funding markets where banks go to get operating capital.

This latest move comes on top of up to $1.5 trillion announced last week. Repo involves banks posting high-quality collateral for reserves used to operate. The minimum bid for the repo operations as been 0.1%.

The repo operations follow other liquidity measures from the Fed aimed at getting banks to keep money moving through the economy.

The coronavirus will be here for "many, many months" and the country must decide on a path forward, infectious disease specialist Michael Osterholm told CNBC. The world is still far from rolling out a vaccine, Osterholm noted, and until then, COVID-19 will present a threat to everyone, especially those most at risk.

"We have to continue to consider what it means to die from this virus. It's a very, very difficult and tragic situation. We also have to have a conversation about how we're going to live with it. We have to figure that out," the director of the Center for Infectious Disease Research and Policy at the University of Minnesota said in a "Squawk Box" interview. "Do we envision an America that for the next 18 months will be in complete lockdown?" —Will Feuer

The Democratic Lamont said that is why social-distancing efforts are so critical. He said they are necessary to ensure a flattening of the curve — essentially trying to limit the surge of coronavirus cases. —Kevin Stankiewicz

Facebook announced a $100 million program to help small businesses as governments throughout the country urge gyms and restaurants to close their doors to slow the coronavirus pandemic.

In a blog post announcing the grants, Facebook said, "We know that your business may be experiencing disruptions resulting from the global outbreak of COVID-19.

Facebook said the grants will be available for up to 30,000 eligible small businesses in over 30 countries. That would be an average of $3,333 per business. It could help businesses experiencing a sharp drop in traffic, but it's a fraction of Facebook's typical revenue. The company generated $21.08 billion in the fourth quarter of 2019 alone. —Lauren Feiner

Travel Economics is forecasting a 10% drop in international visits to the U.S. a year, about double the decline the U.S. faced during the outbreak of severe acute respiratory syndrome, or SARS, in 2003. This implies 8.2 million lost visitors in one year, even more than the 7.7 million international travelers lost in 2001 and 2002, after the 9/11 terrorist attacks. In all, it anticipates 825,000 jobs could be lost in the industry.

The lobby groups have asked for a number of relief measures, including tax credits for employee retention, the deferment of quarterly tax payments, and the ability to carry back net-operating-losses, CNBC has reported. It is unclear what measures the White House is currently considering. —Lauren Hirsch

Democratic Sens. Amy Klobuchar and Ron Wyden are pushing to make vote-by-mail available to every American as the coronavirus pandemic threatens to keep people at home during election season.

"The best way to ensure that this virus doesn't keep people from the ballot box is to bring the ballot box to them. We must allow every American the ability to vote by mail," the two lawmakers wrote in an opinion article in The Washington Post published on Monday. "And we must expand early voting so that voters who are not able to vote by mail are not exposed to the elevated infection risks of long lines and crowded polling locations." —Tucker Higgins

Minneapolis Federal Reserve President Neel Kashkari said the central bank still has monetary policy options to deal with the coronavirus crisis, though negative interest rates still are unlikely.

In a CNBC interview, Kashkari called on Congress to act in situations like a potential bailout for the airline industry. He said the Fed is in the "fourth round" of responders to the crisis, behind health care professionals, the public and Congress.

"We are not at the front line of this," he said on "Squawk Box." "But we do have a job to do and we are using our tools aggressively to try to make sure the financial system is ultimately working." —Jeff Cox

An end to the oil price plunge is nowhere in sight, energy experts say, as futures of international benchmark Brent crude fell below $30 a barrel Monday for the first time since 2016. That's a stunning 54% drop year-to-date.

Uber Technologies began suspending shared rides on its ride-hailing platform in the United States and Canada to limit the spread of the coronavirus.

The pooled option, which allows riders to book trips at lower prices by sharing the car with up to three other passengers traveling in the same direction, has been disabled for users opening the apps in the two countries.

"Our goal is to help flatten the curve on community spread in the cities we serve," senior vice president Uber Rides and Platform Andrew Macdonald said in a statement. —Reuters

There's still a major shortage of testing capacity in the U.S., Dr. Kavita Patel, a nonresident fellow at the Brookings Institute, told CNBC's "Squawk Box." Patel, who served as director of policy for the Office of Intergovernmental Affairs and Public Engagement under Obama, said that even hospitals that have test kits in supply, are running out of the necessary reagents or other supplies like cotton swabs and specific chemicals. She said there's no reason an at-home test could not be developed and made available to Americans across the country. "A test kit, just like anything else in our lives these days, can come to you even in the same day," she said. "Doing it in the comfort of your own quarantined home makes a lot of sense." —Will Feuer

The company had previously said it aimed to have hundreds of thousands of doses ready for human testing in late summer, so the new goal is a significant acceleration. Regeneron said it plans to start large-scale manufacturing by the middle of next month and still plans to ramp up to hundreds of thousands of preventive doses a month by the end of summer. —Meg Tirrell

Car giant Volkswagen is suspending production at its plants in Europe. Production will be halted at Spanish plants, in Setubal in Portugal, Bratislava in Slovakia and at the Lamborghini and Ducati plants in Italy before the end of this week, Volkswagen's CEO said, Reuters reported. Most of the other German and European plants will begin preparing to suspend production, probably for two to three weeks, Volkswagen said.
