WHAT'S HAPPENING TODAY:

— U.S. officials believe China covered up the extent of the coronavirus outbreak to stock up on medical supplies needed to respond to it. Chinese leaders "intentionally concealed the severity" of the pandemic from the world in early January, according to a four-page Department of Homeland Security intelligence report obtained by The Associated Press.

— Reachable only by plane or boat, a small community in the Chesapeake Bay in the eastern United States has reported zero cases of the new coronavirus. But the virus is now as close as it can get without crossing the water, infecting people on the Eastern Shore of Virginia and Maryland.

— "The case is submitted." With those words, Chief Justice John Roberts wrapped up the first U.S. Supreme Court argument conducted by telephone and where audio was available live to the public. The court's plaza was deserted as it has been since the building was closed to the public in mid-March.

— Being homeless in New York City is tougher and scarier now amid the coronavirus pandemic. The city has identified more than 650 cases and more than 50 COVID-19 deaths among the 17,000 single adults in its shelter system.

— World leaders, organizations and banks pledged 7.4 billion euros ($8 billion) for research to find a vaccine against the new coronavirus but warned that it is just the start of an effort that must be sustained over time to beat the disease. The United States was notably absent from the video-conference event hosted by the European Union.

WHAT YOU NEED TO KNOW:

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia and death. The vast majority of people recover.

Here are the symptoms of the virus compared with the common flu.

One of the best ways to prevent spread of the virus is washing your hands with soap and water. The U.S. Centers for Disease Control and Prevention recommends first washing with warm or cold water and then lathering soap for 20 seconds to get it on the backs of hands, between fingers and under fingernails before rinsing off.

You should wash your phone, too. Here's how.

TRACKING THE VIRUS: Drill down and zoom in at the individual county level, and you can access numbers that will show you the situation where you are, and where loved ones or people you're worried about live.
