Brazil has exceeded 2,000 Covid-related deaths in a single day for the first time, as infection rates soar.
The country has the second highest death toll in the world, behind the US, with a total of 268,370 fatalities. Wednesday's total was 2,286.
Experts warn the transmission rate is made worse by more contagious variants
On Wednesday, former leader Luiz Inacio Lula da Silva hit out at President Jair Bolsonaro's "stupid" decisions made during the pandemic.
Mr Bolsonaro, who was pictured wearing a mask for the first time in a month on Wednesday, has consistently sought to downplay the threat posed by the virus. Earlier this week he told people to "stop whining".
The surge in cases has put health systems in most of Brazil's largest cities under immense pressure, with many close to collapse, Brazil's leading public health centre Fiocruz warns.
