Officials in the country are reopening parts of the economy despite chaos in overcrowded hospitals and a collapsed health system in some areas.
Some 4,195 deaths were counted in the previous 24 hours, with the nation's pandemic toll quickly approaching 340,000, the second highest in the world.
Only the US and Peru have had daily death tolls higher than 4,000.
Sao Paulo state, Brazil's most populous with 46 million residents, registered almost 1,400 deaths in the latest count.
Health officials said the figure was partly due to the Easter holiday, which delayed the count.
Local authorities nationwide argue that numbers of cases and hospitalizations are trending downward after a week of a partial shutdown.
Miguel Lago, executive director of Brazil's Institute for Health Policy Studies, which advises public health officials, said reopening is a mistake that he fears will bring even higher death numbers, though he thinks it unlikely to be reversed.
"The fact is the anti-lockdown narrative of President Jair Bolsonaro has won," Lago said.
"Mayors and governors are politically prohibited from beefing up social distancing policies because they know supporters of the president, including business leaders, will sabotage it."
Bolsonaro, who has long downplayed the risks of the coronavirus, remains fully against lockdowns as damaging to the economy.
Covid-19 patients are using more than 90 per cent of beds in intensive care unit in most Brazilian states.
Hundreds of people are dying as they wait for care and basic supplies such as oxygen and sedatives are running out in several states.
Less than 3 per cent of Brazil's 210 million people have received both doses of coronavirus vaccines, according to Our World in Data, an online research site.
