Real Madrid have said its players were being placed in isolation after one of the club’s basketball players, who share facilities with Madrid’s soccer players, tested positive for the COVID-19 coronavirus. That led to the instant decision by the Spanish league to bring matches to a halt for the next two rounds. For most people, the new coronavirus causes only mild or moderate symptoms. For some it can cause more severe illness, especially in older adults and people with existing health problems. (AP Photo/Paul White)
