Global coronavirus cases surpassed 1 million on Thursday with more than 52,000 deaths as the pandemic further exploded in the United States and the death toll climbed in Spain and Italy, according to a Reuters tally of official data.

Italy had the most deaths, more than 13,900, followed by Spain. The United States had the most confirmed cases of any country, more than 240,000, the data showed.

Since the virus was first recorded in China late last year, the pandemic has spread around the world, prompting governments to close businesses, ground airlines and order hundreds of millions of people to stay at home to try to slow the contagion.
