It has also recorded around 37,000 deaths, more than any other nation, followed by Italy, Spain and France which have all been ravaged by their own outbreaks.
Many countries are testing only the most serious cases and the number of confirmed global cases is likely only a fraction of the true total.
Virtually no corner of the world has been left untouched, with deaths in Africa passing 1,000 overnight.

- Cover-up claims -
China sharply raised its own death toll to 4,636 on Friday after adding another 1,290 fatalities for the city of Wuhan, where the respiratory disease first emerged late last year.
Trump, who has angrily shot back at claims he reacted too slowly to the virus threat, has accused Beijing of downplaying the impact of the virus within its borders.
"It is far higher than that and far higher than the U.S., not even close!" he tweeted.
Trump did not offer evidence to back the claim, but pressure has mounted in recent days on Beijing to come clean over its handling of the initial outbreak.
Leaders in France and Britain have also questioned China's management of the crisis but Beijing hit back, saying it had not concealed information about the illness.

Germany's health minister said infection rates had "sunk significantly" after 3,400 deaths in his country, which is now beginning the delicate task of lifting some restrictions without triggering a secondary outbreak.

The Trump administration pledged another $19 billion in relief for farmers reeling from a massive jolt to the agricultural markets with schools and restaurants shuttered across the country.
Part of the funds will be used to buy up surplus dairy products and produce that farmers have been destroying, unable to get it to consumers or food processors.
"Having to dump milk and plow under vegetables ready to market is not only financially distressing, but it's heartbreaking as well to those who produce them," agriculture secretary Sonny Perdue said.
African state leaders and global financial bodies warned on Friday that the continent needed tens of billions of dollars in additional funds to fight the outbreak.
The IMF also warned the virus could spark another "lost decade" in Latin America and backed debt moratoriums to free up spending for the region's fragile economies.
