There have been 794,000 deaths directly attributable to the disease.
Here's the latest from around the world overnight.

Britain recorded 1182 new coronavirus cases on Thursday, the second-highest daily total since June 21, government figures showed.

No new deaths were reported, but the region's Health Minister, Robin Swann, said the reproduction rate, or the number of people who become infected from each positive case, was likely to be around 1.3. Whenever the reproduction rate is above 1, the epidemic is increasing.
Germany's health authorities can cope with the rising number of infections at present, the deputy director of the Robert Koch Institute for infectious diseases told Reuters, but urged people to do everything to help reverse the trend.
The number of new daily cases in Germany has been rising steadily since early July and has accelerated in recent weeks, driven by partying and people returning from holiday in countries where there is a high risk of catching the virus.
On Thursday, the number of confirmed cases climbed by 1707 to 228,621, marking the biggest daily increase since April 26.
Italy reported 845 new coronavirus infections in the past 24 hours, the health ministry said on Thursday, marking the highest daily increase since May, when the government eased its rigid lockdown measures.

Africa is beginning to slowly "bend the curve" of COVID-19 infections as measures like mask-wearing and social distancing slow down the spread of the pandemic on the continent, the Africa Centres for Disease Control and Prevention said on Thursday.
Although the spread of the COVID-19 outbreak was slow in Africa in the early stages of the pandemic, the rate of infection gradually accelerated especially in South Africa, which now accounts for more than half of its case load of more than 1.1 million.
On average, there were signs of a decline in new infections across Africa over the last two weeks, said John Nkengasong, head of Africa CDC.
"So I think that is really some sign of hope that we are beginning to bend the curve slowly. We take this news with cautious optimism," he said.
Almost 30 percent of the population in India's capital of New Delhi likely have been infected by the novel coronavirus, according to a serological survey of 15,000 people conducted by the local government, a figure that indicates infection numbers are much higher than those recorded.
Thailand sought to allay fears of a second wave of coronavirus infections on Thursday, after a woman tested positive having cleared quarantine nearly two months ago on returning from overseas.

New York City Mayor Bill de Blasio on Thursday doubled down on his commitment to reopen schools for in-person learning next month, a day after the city's teachers union said his reopening protocol was insufficient to prevent the spread of COVID-19.
"We are going to make sure these schools are safe and ready. And if we don't think they're safe and ready, they won't reopen," de Blasio said on Thursday.
Compared to De Blasio's threshold of a 3 percent COVID-19 infection rate for schools to shut down again, the city's positive test rate on Thursday was 0.88 percent.
New York City teachers on Wednesday threatened to strike or bring legal action unless the city government addresses specific safety demands like a more rigorous COVID-19 testing plan and protocols for isolating students who show symptoms of the virus.
No more parties and events in homes listed on Airbnb, the short-term home rental company said on Thursday as it tries to enforce strict social-distancing norms to fight the COVID-19 pandemic.
The new rules include a cap on occupancy at 16, with hosts or guests who try to skirt the rules facing a ban from Airbnb's community and even legal action, the company said on Thursday.
"Instituting a global ban on parties and events is in the best interest of public health," Airbnb said in a statement, adding that the ban applies to all future bookings.
