The South American country also recorded more than 1,200 deaths for the fourth consecutive day as the total fatality count neared 49,000.
Infections have soared tenfold in Brazil over the past month after first surpassing 100,00 coronavirus cases on May 3.
And some experts fear the real infection number could be as many as ten million due to Brazil’s lack of testing and the government’s flippant attitude to the pandemic.
It comes after the US became the first country to break one million cases on April 27 – and continues to be the world leader with almost 2.3million cases.
Russia is third the worldwide totals with 576,952 cases, with India fourth at 396,661 and the UK in fifth with 301,815.
Brazil’s grim milestone came just days after Pan American Health Organisation (PAHO) Director Carissa Etienne said Brazil was a major concern.
And World Health Organisation director general Tedros Adhanom Ghebreyesus warned the pandemic was now entering a “new and dangerous” stage.
He warned cases were rising fast at the same time as governments were beginning to ease their lockdowns – as fears loom worldwide of a potential second wave.
Brazil – which has a population of 211million – is also heading into its winter, which can worsen respiratory illnesses like Covid-19.
President Jair Bolsonaro had insisted the virus was “just a little flu” and consistently downplayed the threat from the pandemic.
His country is now paying the price, but his regime continues to claim that everything is under control despite the soaring numbers.
Walter Braga Netto, the head of the office of the Brazilian president’s chief of staff, said: “There is a crisis, we sympathize with bereaved families, but it is managed.”
