On Tuesday, the Brazilian government approved a partial return of fans to the football stadiums.
"It is important to emphasize that the reopening of the stadiums must not exceed 30% of the capacity of each stadium," the Brazilian Minister of Health said in a brief statement.
He added that this percentage could increase at a later time if required.
The decision will allow the attendance of about 25,000 spectators at the Maracana Stadium in Rio de Janeiro, and came after the Brazilian Game Federation asked health officials in the country to take a decision on its proposal to return fans to closed stadiums since last March when football matches were stopped due to the Corona outbreak.
Brazilian media reported that cities could reject the decision, with Belo Horizonte saying it would oppose the return of fans to the stadiums.
Hundreds of people still die every day in Brazil, one of the countries most affected by the virus, and the decision comes on the same day that the British government halted plans to allow fans to return to watch matches from stadiums.
The games resumed at the professional level again last June in Rio de Janeiro and the state of Sao Paulo last July.
Despite this, the clubs are struggling to keep their players free of the virus.
For example, Brazilian champion Flamengo was preparing for a match in Ecuador in the Copa Libertadores today, but 7 of his players and two members of the coaching staff were infected with Corona before the match.
More than 136,000 people have died from the virus in Brazil, the second-highest rate of fatalities from the virus in the world after the United States.
