High-level sports was one of the first social activities shut down by the coronavirus pandemic and many athletes, who play in front of crowds and train with team-mates, have been among the high-profile victims.
While only one sports personality, the 76-year-old former Real Madrid president, Lorenzo Sanz, has so far died, those infected spread across the age range and the sporting spectrum, with clusters in Italian football, the NBA and cycling.
The numbers could be higher because not all clubs are testing.
Valladolid in the Spanish Liga rejected test kits saying they should be used on those who need them.
The NBA's Golden State Warriors said they would only test players with symptoms.
"We're treating ourselves like people, which is what we are," said general manager Bob Myers. "We're just a basketball team."
Here, AFP Sport looks at some of the most high-profile cases.
