The U.S., home to about 4% of the global population, has reported about one-third of the world’s more than 3 million known coronavirus infections. The first known cases of the virus in China began appearing in December. It took nearly four months for the number of confirmed cases in the U.S. to hit 500,000 on April 10.
Of the more than 213,000 people who have died of COVID-19 worldwide, roughly 25% ― or about 57,000 deaths ― have occurred in the United States.
