The capacity to test a vast number of people for coronavirus does not yet exist, Dr. Todd Ellerin, chief of infectious diseases at South Shore Health in Weymouth, Massachusetts, told ABC News.

Adams advised people to "know your risk," "know your circumstances," and "know the steps that you can take to prepare," such as not touching your face, not shaking anyone's hands and washing your hands frequently with soap and water for 20 seconds.
"There are things that we can do to prepare and not panic," he added. "But people should know that this is going to likely get worse before it gets better."
