President Trump said on Sunday that federal guidelines urging Americans to social distance to slow the spread of the coronavirus will remain in place for another month.

"During this period, it's very important that everyone follow the guidelines," Trump said at a news conference in the Rose Garden. "The better you do, the faster this whole nightmare will end."

A planeload of health care supplies arrived in New York City on Sunday from China, part of an effort the White House says will expedite the arrival of goods that are badly needed to fight the coronavirus pandemic.

The nation's leading expert on infectious diseases and member of the White House's coronavirus task force says the pandemic could kill 100,000 to 200,000 Americans and infect millions.

Dr. Anthony Fauci said based on modeling of the current pace of the coronavirus' spread in the U.S., "between 100,000 and 200,000" people may die from COVID-19, the disease caused by the novel coronavirus.

Academic science labs around the U.S. are rapidly gearing up to run coronavirus tests for patients in need. They're drawing resources from across campus: technology, chemicals and a formidable workforce — graduate students.

"Normally, when people say they need someone in an emergency, it's not a science grad student," says Katie Cabral, a bioengineering Ph.D. student at the University of California, San Francisco. "But in this case, my particular qualifications are exactly what is needed."
