More than 200 colleges and universities across the U.S. have closed in an effort to stop the spread of COVID-19.

"Some colleges do not mention refunds," said Mark Kantrowitz, a higher education expert. "I would not be surprised if colleges that refuse to provide room and board refunds will face class action lawsuits." —Annie Nova

Servino Ristorante, an upscale Italian restaurant in Tiburon, California, is a short drive or ferry ride from San Francisco, where scores of software and internet companies have emerged over the past decade.
Normally the 42-year-old restaurant, with picturesque views of the Bay, benefits from the thriving local tech economy. But with companies including Google, Facebook and Salesforce instructing their employees to work from home amid concerns about the spreading coronavirus, Servino has to figure out how to survive a looming crisis.
Corporate events in the banquet hall have all been canceled, said Natale Servino, general manager of the family-owned business. And there's been a big dip in diners coming in from San Francisco.
For people with full-time salaried jobs that come with health coverage and paid leave, the current state of affairs is very inconvenient, and many retirement accounts are looking scary. But for those working at businesses like Servino, who are facing either dramatically reduced income or the prospect of having to find childcare should their kids' school close, the potential impact of the coronavirus is dire. It may be hard to pay rent or put food on the table. —Ari Levy
Tufts Medical Center in Massachusetts started calling patients earlier this week to reschedule elective procedures, such as knee and hip replacements and even annual physical exams, so it could prepare for an influx of patients with coronavirus.

"We also saw a reality of limited stock, including personal protective equipment, across the industry," he continued.
Hospitals in the U.S. are facing mounting pressure to stop performing elective and non-urgent procedures, which represent a major chunk of their annual revenues. Public health officials fear that if these surgeries continue, they'll sap important supplies and resources that might be needed for the most serious coronavirus cases. — Christina Farr

Donald Trump was at the same dinner table as a guest who later tested positive for COVID-19, the president's physician said Friday.
