The governing body of world football said on Tuesday that Infantino has mild symptoms and "has immediately placed himself in self-isolation and will remain in quarantine at least for 10 days".

People who have come into contact with the 50-year-old Swiss lawyer in recent days have been informed "to take the necessary steps," FIFA said.

Infantino has travelled little during the coronavirus pandemic but he attended a signing ceremony at the White House last month to mark normalised relations for Israel with the United Arab Emirates and Bahrain.

Infantino's infection comes as Switzerland reports a spike in COVID-19 cases.

Switzerland has reported 127,000 cases this year, with more than 23,000 since last Friday.
