Brazil has become the second country, after the US, to enlist in excess of 50,000 deaths from Covid-19.
It comes in the midst of developing political distress and days after the country confirmed more than one million coronavirus cases.
Specialists warn that the peak of the outbreak in Brazil is still weeks away.
The World Health Organization (WHO) has recorded the greatest one-day increment in cases, with the Americas responsible for most of the new infections.
Of the 183,000 new cases reported in 24 hours, over 60% were from North and South America, the agency said.
However, the growing outbreak didn’t stop a huge number of supporters and opponents of Brazil’s far-right President Jair Bolsonaro from talking to the streets in rival protests on Sunday.
Anti-government demonstrators are calling for Mr Bolsonaro to be impeached. It follows the arrest on Thursday of a former aide and family friend who is accused of corruption.
His supporters say Congress and the Supreme Court are trying to curb his forces.
Mr. Bolsonaro has additionally been vigorously censured for his reaction to the coronavirus episode. He has restricted lockdowns and openly disagreed with advice from his government’s own health ministry.
On Sunday, the service declared that 641 additional deaths had been enrolled in the previous 24 hours, taking the aggregate to 50,617. Over the same period it also registered more than 17,000 new infections.
Just the US has fared worse, with 2.2 million cases and about 120,000 deaths.
Mr. Bolsonaro argues that the economic impact of the measures will be a lot greater than the infection itself, a position shared by many. But his overall approach to the crisis has led to the resignation of two doctors as health minister.
There was no national lockdown, yet states and urban areas received their own measures. After months of restrictions, some are slowly being lifted, even though infection levels remain high.
There is still worry that the wellbeing framework will be not able to adapt in certain spots, and that the infection is spreading quicker in denied neighborhoods and remote areras, such as indigenous communities, where access to adequate care is difficult.
As well as the pandemic, Mr Bolsonaro is facing a growing political crisis. He is under investigation for allegedly trying to interfere with the police for political motives, which he denies, while the Supreme Court is carrying out two separate inquiries into his allies.
On Sunday, police in the capital, Brasilia, kept rival groups apart as they marched outside Congress and the Supreme Court building. Other large gatherings took place in São Paulo and Rio de Janeiro.
