The number of confirmed coronavirus cases worldwide topped 20 million, more than half of them from the United States, India and Brazil.
Russia has reported more than 890,000 cases, the fourth-most in the world, according to a Johns Hopkins University tally that also showed total confirmed cases globally surpassing 20 million.
It took six months or so to get to 10 million cases after the virus first appeared in central China late last year. It took just over six weeks for that number to double.
An AP analysis of data through August 9 showed the US, India and Brazil together accounted for nearly two-thirds of all reported infections since the world hit 15 million coronavirus cases on July 22.
Health officials believe the actual number of people infected with the virus is much higher than that tally kept by Johns Hopkins University, given testing limitations and that as many as 40 percent of those with the virus show no symptoms.
In Europe, countries that appeared to have gotten their outbreaks under control during nationwide lockdowns and lifted many public restrictions worked to prevent a resurgence of the virus. Finland joined France and Germany in announcing it would test travelers from at-risk countries upon arrival.
Spain, which along with Italy was hardest hit when the virus first exploded on the continent, now has the most confirmed cases in Western Europe at nearly 323,000. The number of new cases has risen steadily in Spain since its strict, three-month lockdown ended on June 21, reaching 1,486 on Monday. In Greece, which imposed strict lockdown measures early and kept its reported cases low during the height of the European epidemic, the government announced new measures Monday to prevent an outbreak. It ordered bars, restaurants and cafes in several regions to shut between midnight and 7 am.
