In less than 10 months, the US went from one known coronavirus infection to 10 million.
That bleak milestone was reached Monday, according to data from Johns Hopkins University. And the most recent 1 million infections happened faster than any previous million, in just 10 days.
The virus is now spreading exponentially in all regions of the country. As of Monday, 43 states reported at least 10% more new Covid-19 cases compared to last week, according to Johns Hopkins.
And the rate of new infections is far outpacing the rate of testing.
The average daily number of new cases soared 34% over the past week, but testing has only increased 7.41% over the past week, according to data from the Covid Tracking Project.
"We absolutely need more testing. Cases are rising faster than testing rates are rising," said Dr. Rochelle Walensky, a professor of medicine at Harvard Medical School.
Track the virus in your state and nationwide
With every surge in new infections comes new hospitalizations and deaths. More than 238,000 people have died from Covid-19 in the US, according to Johns Hopkins.
But amid the horrific trends, there's some good news on the vaccine front.
One vaccine may be 90% effective
On Monday, the drugmaker Pfizer said early data show its Covid-19 vaccine is more than 90% effective.
More than 43,000 volunteers had received either two doses of the vaccine or a placebo.
A so-called interim analysis looked at the first 94 coronavirus infections among the group. Fewer than 10% of infections were in participants who had been given the vaccine. More than 90% of the cases were in people who had been given a placebo.
Pfizer said it plans to seek emergency use authorization from the US Food and Drug Administration soon after volunteers have been monitored for two months after getting their second dose of vaccine, as requested by the FDA.
That request could be made by the third week of November.
Pfizer CEO Albert Bourla said so far, the vaccine has shown no safety problems.
"But we need to wait until the results are there," Bourla told CNN Chief Medical Correspondent Dr. Sanjay Gupta.
It's not clear exactly when the vaccine might be publicly available to most Americans. But when it is, "the vaccine will be available for free to all American citizens," Bourla said.
Another Pfizer official said at a news conference it is not yet clear how long the vaccine offers protection.
"We will be learning about that from the current clinical trial," Dr. John Burkhardt, Pfizer's vice president of Global Drug Safety Research and Development, told reporters.
Michael Osterholm, the director of the Center for Disease Research and Policy at the University of Minnesota, said he was encouraged by Monday's news but wants to see more data as the trial continues.
"I'm a bit more cautious than others, maybe, because what we heard is that the vaccine is 90% effective or efficacious, but we don't know 90% for what, for a common cough and fever, is it for severe disease and hospitalizations and death?" he said.
"We really need that kind of information to be able to determine just what impact this vaccine will have," said Osterholm, who President-elect Joe Biden has announced as a member of his Covid-19 pandemic advisory board.
'Pouring gasoline on a fire'
While America waits for a vaccine, coronavirus is raging at levels never before seen during the pandemic.
The US has averaged 108,737 new Covid-19 cases a day over the past week -- a record high, according to Johns Hopkins.
The most infections ever reported in one day was on Saturday, with 128,412 new cases.
"Over the last week, about 23 states in all regions of the country reported record (new) cases," Walensky said.
"The death rates are high, and in fact they represent case counts from two to three weeks ago. So that's when we had case counts in the 60,000-70,000 range. So you can imagine what's going to happen in the weeks ahead."
And 19 states reported record-high Covid-19 hospitalizations over the weekend, according the Covid Tracking Project.
Emergency medicine physician Dr. Megan Ranney said the US is "heading into the very worst of this pandemic,"
"We're about to see all of these little epidemics across the country, crossed and mixed," Ranney said.
"It's going to be an awful lot like pouring gasoline on a fire," she said.
LA health official: People celebrating, protesting should get tested
After seeing "real and alarming increases" in Covid-19 cases, Los Angeles Health Director Barbara Ferrer is recommending that anyone who didn't regularly stay 6 feet away from others or wear a face covering at celebrations or protests get a coronavirus test.
"If you're going out in these large crowds and you're singing, shouting, celebrating, or protesting and don't have a mask on or you're not keeping your distance, there's a lot of transmission happening there," Ferrer said. "If you've been in those situations, you may have been exposed so please quarantine and go get tested."
Los Angeles County, home to 10 million people, added 1,413 new cases Monday, bringing the total number of cases since the pandemic start to 323,625. There are 855 people currently hospitalized due to the virus, Ferrer said.
'We must ... avoid further devastation'
Of the 43 states where new cases soared more than 10% this past week, 10 states have seen increases of more than 50%: Hawaii, Iowa, Kansas, Maine, Minnesota, Nebraska, Oklahoma, Oregon, Vermont and Washington state.
No state has decreased the rate of new infections by more than 10% this past week.
Utah is one of many states cracking down with new mitigation efforts.
Gov. Gary Herbert issued an executive order Sunday declaring a state of emergency and issuing a mask mandate for all of Utah.
He also limited social gatherings to households only until November 23.
"Hospitalizations and ICUs are nearing capacity and healthcare providers will be unable to care for Utahns in the coming days if this surge continues," the governor's office said in a statement.
"We must take action now to protect our hospitals and healthcare workers and to avoid further devastation on our families, communities, and businesses."
