The increase comes less than two weeks after Halloween.
A pandemic of the novel coronavirus has now killed more than 1.3 million people worldwide.
Over 53.2 million people across the globe have been diagnosed with COVID-19, the disease caused by the new respiratory virus, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some national governments are hiding or downplaying the scope of their outbreaks. The criteria for diagnosis -- through clinical means or a lab test -- has also varied from country to country.
Since the first cases were detected in China in December, the virus has rapidly spread to every continent except Antarctica. The United States is the worst-affected nation, with more than 10.7 million diagnosed cases and at least 244,283 deaths.
Nearly 200 vaccine candidates for COVID-19 are being tracked by the World Health Organization, at least 10 of which are in crucial phase three studies. Of those 10 potential vaccines in late-stage trials, there are currently five that will be available in the United States if approved.
In Utah, where the seven-day positivity rate stands at 23.2%, cases are "accelerating," said Gov. Gary Herbert.
"The positivity rate should cause us all concern," Herbert said.
The governor warned, "The rooms in intensive care units are getting to the point of being overcrowded." Hospitals are at 87.5% capacity, said state epidemiologist Dr. Angela Dunn.
Georgia Secretary of State Brad Raffensperger, a Republican who held a news conference Wednesday in the wake of the presidential election, is now self-quarantining after his wife tested positive for COVID-19, Raffensperger's deputy, Jordan Fuchs, told ABC News.
The secretary of state will be tested and results will be released.

A stay-at-home advisory will go into effect in Chicago on Monday morning "due to the alarming and ongoing surge in COVID-19 cases," Mayor Lori Lightfoot announced Thursday.
Lightfoot is asking residents to "stay home unless for essential reasons" and "stop having guests over—including family members you do not live with."
She's urging residents to avoid nonessential travel, including canceling traditional Thanksgiving plans.
"Our goal now is the same as it was during the first surge: bend the curve. The more we bend the curve, the more we can reopen our businesses and get our lives back to some sense of normalcy," she tweeted.
Ohio has set another one-day record with 7,101 new COVID-19 cases.
This also marked Ohio's second-highest day of hospital admissions with 268 people admitted, Gov. Mike DeWine said Thursday.
"We are currently at our highest point for both hospitalized and ICU patients since the beginning of the pandemic," DeWine said.
Over 274,000 people have been diagnosed and at least 5,658 people in the state have died.
DeWine announced new restrictions on Wednesday, including that universities will be remote after Thanksgiving businesses must post mask requirement signs at their entrances.
