The devastating number of cases are followed by Brazil and India. Currently, the global tally of coronavirus infections stands at more than 20 million.
Of that sky-rocketing figure, over 733,000 people have died of COVID-19-related complications.
But health officials claim the figures could be much higher than the total published by Johns Hopkins University.
Testing constraints and asymptomatic patients mean that the estimation of an exact number is practically impossible.
Since coronavirus emerged last year, ten million cases were reported within six months, but the number of infections has doubled in just six weeks afterward.
In April, the number of infections steadied thanks to the imposition of lockdowns.
But the figures only surged again as countries began to ease their lockdown restrictions.
The seven-day average for new daily infections has remained above a quarter of a million for the past two weeks.
The surge was led in large part by Latin America, the Caribbean and Asia.
Daily infection figures are surging in four states, levelling off in another 23 and decreasing in the remaining 23.
But the number of deaths is surging in 19 states, according to analysis by The New York Times.
Yesterday, India recorded almost 54,000 new infections, taking its total close to 2.3 million.
But India’s claimed fatality rate of 2 percent is far lower than the one in the US and Brazil.
The figures come after, on Monday, US President Donald Trump said that Scott Atlas, a healthcare policy expert at the conservative Hoover Institution at Stanford University, “will be working with us on the coronavirus”, adding that Atlas “has many great ideas”.
