— Nearly 1.9 million people applied for U.S. unemployment benefits last week, the ninth straight decline since applications spiked in mid-March, a sign that the gradual reopening of businesses has slowed the pace of layoffs.

— A malaria drug President Donald Trump took to try to prevent COVID-19 proved ineffective for that in the first large, high-quality study to test it in people in close contact with someone with the disease. Results published by the New England Journal of Medicine show that hydroxychloroquine was no better than placebo pills at preventing illness from the coronavirus.

— Emergency room visits in the U.S. for chest pain and heart attacks fell early this spring, according to a study that supports fears that the coronavirus outbreak scared away people from going to the hospital. The Centers for Disease Control and Prevention reports visits were up for respiratory illnesses and pneumonia, but were down for nearly every other kind of injury or ailment.

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.

ONE NUMBER:

— 168,000: That's how many cars were registered in Germany last month, down 50% from a year earlier, according the German Association of the Automotive Industry.

IN OTHER NEWS:

— MUSEUM GIFT: If it hadn’t been for the pandemic, Amsterdam's Rijksmuseum would likely have to do without a classic Dutch 16th century painting it so badly craved. But the sale of Bartholomeus Spranger’s “Body of Christ Supported by Angels” was canceled early in the corovavirus crisis, and art dealer Bob Haboldt chose to donate it instead to the famed museum.

— FAUCI THE COLT: A racehorse named for Dr. Anthony Fauci reached the finish line at a safe enough distance from others that would have made his namesake proud. Fauci, the 2-year-old colt named for the director of the National Institute of Allergy and Infectious Diseases, finished a distant second to a horse named Prisoner and was well ahead of third-place Indoctrinate in his much-anticipated debut at Belmont Park.
