Brazil has topped 300,000 confirmed Covid-19 deaths, becoming the second country to do so amid a spike in infections.
The South American country has reported record death tolls in recent days.
The US reached the grim milestone on December 14, but has a larger population than Brazil.
On Wednesday, Brazil's health ministry reported 2,009 daily Covid deaths, bringing its pandemic total to 300,685.
A day earlier the country suffered a single-day record of 3,251 deaths.
According to local media reports, the latest coronavirus figures might be affected by changes in the government's counting system.
Newly appointed Health Minister Marcelo Queiroga said in a press conference he would check whether the numbers had been artificially reduced.
With daily death tolls at pandemic highs, state governors and mayors in Brazil have expressed fears that April could be as bad as March for the country's hospitals.
Just in the past 75 days, Brazil has registered 100,000 confirmed coronavirus deaths.
Health experts have blamed the spike on a lack of political coordination in fighting the virus, new variants that spread more easily and a disregard for health protocols.
President Jair Bolsonaro on Wednesday held a meeting with the heads of other government branches to coordinate anti-virus efforts.
He did not propose any policies to deal with the pandemic.
Mr Bolsonaro has consistently downplayed the severity of the pandemic, insisting the economy must be kept humming to prevent worse hardship, and has criticised health measures imposed by local leaders.
