A dozen Venezuela players and coaching staff have tested positive for COVID-19 a day before their Copa America opener against the host in Brasilia, Brazilian health authorities said on Saturday.

The health secretariat of the Federal District, which includes Brasilia, said in a statement that all of the infected people were isolated in a hotel. None of the Venezuelans were named.

CONMEBOL has not said if the match against Brazil on Sunday at Mane Garrincha Stadium will proceed as scheduled or be delayed.

``They are all asymptomatic, isolated in single rooms and are being monitored by the team of CONMEBOL`` and local specialists, the statement said.

CONMEBOL has not responded to a request for comment from The Associated Press.

Venezuela arrived in Brazil on Friday. One day earlier, two players tested positive for COVID-19, Wilker Angel and Rolf Feltscher. They did not come to Brazil, the emergency host of the tournament after Colombia and Argentina were pulled.

Brazil has the second-most recorded deaths from the coronavirus in the world, more than 480,000. President Jair Bolsonaro, a critic of social distancing policies, is the main advocate for the Copa America, though it will not be attended by spectators.
