Hospitals are overcrowded, with people dying as they wait for treatment in some cities, and the health system is on the brink of collapse in many areas.
The country's total death toll is now almost 337,000, second only to the US.
But President Jair Bolsonaro continues to oppose any lockdown measures to curb the outbreak.
He argues that the damage to the economy would be worse than the effects of the virus itself, and has tried to revert some of the restrictions imposed by local authorities in the courts.
Speaking to supporters outside the presidential residence on Tuesday, he criticised quarantine measures and suggested without evidence that they were linked to obesity and depression. He did not comment on the 4,195 deaths recorded in the past 24 hours.
To date, Brazil has recorded more than 13 million cases of coronavirus, according to the health ministry. Some 66,570 people died with Covid-19 in March, more than double the previous monthly record.
