The number of coronavirus cases topped 20 million on Tuesday, more than half of them from the US, India and Brazil.
Health officials believe the actual number is much higher than that tally kept by Johns Hopkins University, given testing limitations and the fact that as many as 40% of those who are infected have no symptoms.
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 Aug. 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.
The number of new daily cases has continued to rise in India, hitting a rolling seven-day average of 58,768. In the US, which has more than 5 million cases, the average has decreased since July 22nd, but remains high at 53,813 new cases a day.
In the 45 days it took reported infections to double to 20 million, the number of reported virus deaths climbed to 736,191 from 499,506, according to the Johns Hopkins count. That's 236,685 new deaths, an average of more than 5,200 a day.
About one-fifth of reported deaths, or more than 163,000, have been in the US, the highest in the world.
According to AP, caseloads are still rising quickly in many other countries, including Indonesia and Japan.
