Over 66,000 thousand people died in Brazil in March due to the novel coronavirus.
This is more than double the previous monthly record, figures show, BBC reported.
The country’s health service has been pushed to the brink as cases of the virus continue to climb.
President Jair Bolsonaro has faced intense criticism for his handling of the crisis and was hit by high-profile resignations this week.
Wednesday also saw a further 3,800 new deaths and over 90,000 new coronavirus cases. Brazil’s daily deaths currently account for about a quarter of all coronavirus fatalities in the world.
