Millions of people in Europe, the United States and other countries are locked down at home in an effort to stop the spread of the new coronavirus. The number of cases is now higher outside of China, where the virus first appeared, than inside. Speaking from the White House, American President Donald Trump asked older Americans to stay home. He urged everyone to avoid gatherings of more than 10 people for the next 15 days. He also said people should limit travel and social visits and stop going out to eat at restaurants.
