"It is possible to open up at a judicious pace and coexist with the virus, but it requires millions and millions of people to do the right thing. Right now, we don't have that" because people have let their guard down, Boom said.
The number of newly confirmed coronavirus cases across the country per day has reached more than 26,000, up from about 21,000 two weeks ago, according to an AP analysis of data compiled by Johns Hopkins University. The analysis looked at a seven-day rolling average to yesterday.
Over 120,000 deaths in the US have been blamed on the virus.
Over the weekend, the virus seemed to be everywhere at once: Six staff members helping set up for President Donald Trump's rally in Tulsa, Oklahoma, tested positive, as did 23 Clemson University football players in South Carolina. At least 30 members of the Louisiana State University football team were isolated after becoming infected or coming into contact with someone who was. Meatpacking plants were also hit with outbreaks.
In Orlando, 152 coronavirus cases were linked to one bar near the University of Central Florida campus, said Dr. Raul Pino, a state health officer in the resort city.
"A lot of transmission happened there," Pino said. "People are very close. People are not wearing masks. People are drinking, shouting, dancing, sweating, kissing and hugging, all the things that happen in bars. And all those things that happen are not good for Covid-19."
Although he asked health officials to renew calls for people to wear masks and keep their distance, Governor Ron DeSantis has not signalled he will retreat from reopening the state after three months of shutdowns that have damaged the economy.
Dr Michael Ryan, the World Health Organisation's emergencies chief, said that the outbreak is "definitely accelerating" in the US and a number of other countries, dismissing the notion that the record daily levels of new Covid-19 cases simply reflect more testing.
He noted that numerous countries have noted marked increases in hospital admissions and deaths.
"The epidemic is now peaking or moving towards a peak in a number of large countries," he warned.
Arizona, in particular, is seeing disturbing trends in several benchmarks, including the percentage of tests that prove positive for the virus. Arizona's is the highest in the nation.
The state's positive test rate is at a seven-day average of 20.4 per cent, well above the national average of 8.4 per cent and the 10 per cent level that public health officials say is a problem. When the positive test rate rises, it means that an outbreak is worsening — not just that more people are getting tested.
At Maryland's Fort Washington Medical Centre on the outskirts of the nation's capital, workers described a scramble to find new beds, heartbreaking interactions with family members of critically ill patients and their frustration with Americans who do not believe the coronavirus threat is real.
"Everybody is out lounging on the beaches. Just thinking that it's over. And it's not," respiratory therapist Kevin Cole said. "It's far from being over. And unfortunately, it's those people that keep we'll keep this pandemic going."
New York City, once the most lethal hot spot in the US, lifted more of its restrictions Monday, moving a big step closer to normal.
Eve Gonzalez, a 27-year-old food industry worker in New York whose job had not yet resumed, said it was too soon: "I'm dying to go out, but people's health is more important."
Nine million people have been confirmed infected by the virus worldwide and about 470,000 have died, according to Johns Hopkins, though experts say the actual numbers are much higher because of limited testing and cases in which patients had no symptoms.
Amid the global surge, the head of WHO warned that world leaders must not politicise the outbreak but unite to fight it.
Tedros Adhanom Ghebreyesus, who has faced criticism from President Donald Trump, said during a videoconference for the Dubai-based World Government Summit that it took over three months for the world to see one million confirmed infections, but just eight days to see the most recent one million cases.
Tedros did not mention Trump by name or his determination to pull the US out of the UN health agency but warned against "politicising" the pandemic.
"The greatest threat we face now is not the virus itself, it's the lack of global solidarity and global leadership," he said. "We cannot defeat this pandemic with a divided world."
Trump has criticised the WHO for its early response to the outbreak and what he considers its excessive praise of China, where the outbreak began, though his own administration's response in the US has come under attack. Trump has threatened to end all US funding for the WHO.
Companies around the world are racing to find a vaccine, and there is fierce debate over how to make sure it is distributed fairly.
WHO special envoy on Covid-19, Dr David Nabarro, said he believes it will be "2 1/2 years until there will be vaccine for everybody in the world."
India's healthcare system has been slammed by the virus. The country's caseload climbed by nearly 15,000 today to over 425,000, with more than 13,000 deaths.
After easing a nationwide lockdown, the Indian Government in recent weeks ran special trains to return thousands of migrant workers to their home villages.
In Pakistan, infections are accelerating and hospitals are having to turn away patients, with new cases up to 6800 a day.
The Government has relaxed its coronavirus restrictions, hoping to salvage a near-collapsed economy in the country of 220 million people.
