(CNN) -- The country's fall Covid-19 surge is well underway and ramping up: Daily infection tallies are regularly setting records, officials are reporting sharp increases in hospitalized patients and daily deaths are now also climbing.
The US reported more than 1,140 coronavirus deaths Friday, the fourth straight day that count has risen above 1,000. The last time that happened was in August, Johns Hopkins University data show.
Since the start of the pandemic, more than 236,000 have died of Covid-19 in the US. Another 106,000 could lose their lives in the next two months, according to projections from the University of Washington's Institute for Health Metrics and Evaluation.
With the virus running rampant in the country, many state leaders have pushed to implement new measures to curb the spread and avoid more hospitalizations and loss of life. Experts have warned that unless Americans heed safety guidelines like wearing masks and social distancing, things could get much worse.
"We're going to see these case numbers really start to explode," Dr. Scott Gottlieb, former Food and Drug Administration commissioner, told CNBC on Friday.
That's a bleak outlook, considering this week saw multiple new highs. The US beat its own record of new daily cases for three days straight, topping 100,000 a day since Wednesday.
On Friday, the US reported more than 126,000 new cases -- the highest one-day tally yet, Johns Hopkins data show. As of Saturday morning, more than 9.7 million cases have been recorded in the US.
On the same day, at least 17 states reported record high cases counts for a single day, per the Johns Hopkins data. Sixteen states reported record-high Covid-19 hospitalizations, according to the COVID Tracking Project. More than 54,000 coronavirus patients are now hospitalized across the country -- not far from the country's pandemic peak of 59,940 in mid-April -- according to the project.
"We're building up a lot of trouble for the future," Gottlieb told CNBC "You have to be really worried what January is going to look like, what December is going to look like right now, given the way this is rising."
Officials look to President-elect Biden for renewed Covid-19 response
On Saturday, CNN projected former Vice President Joe Biden will become the next President of the United States, and he plans to announce a 12-person coronavirus task force on Monday, two sources with knowledge told CNN.
The task force will be headed by three co-chairs, including former Surgeon General Dr. Vivek Murthy, former Food and Drug Administration Commissioner Dr. David Kessler and Yale University's Dr. Marcella Nunez-Smith. The move signals how seriously Biden plans to focus on the coronavirus from the outset of his transition.
Shortly after CNN and other networks projected Biden as the winner of the election, political leaders expressed confidence in Biden's future response to Covid-19 when he takes office.
Michigan Gov. Gretchen Whitmer -- a Democrat whose state, like many others, has been battered by the virus -- congratulated Biden in a statement, adding, "Now, with the election behind us, it is time for the American people to unite against our common enemy: COVID-19."
"To our newly elected leaders, from the White House down to the Michigan State Legislature, let's roll up our sleeves, work together, and beat this virus once and for all," Whitmer said.
Washington Gov. Jay Inslee, a Democrat, said he expected Biden and Vice President-elect Kamala Harris to "lead a strong and science-based approach to fighting the COVID-19 pandemic and rebuilding our economy and addressing the hardship faced by millions."
Democratic Sen. Mark Warner of Virginia highlighted the infections, deaths and unemployment that have occurred as a result of Covid-19, writing on Twitter, "The first order of businesses needs to be getting (Covid-19) under control & passing a relief package for the American people."
Canadian Prime Minister Justin Trudeau underscored the importance of his country's partnership with the United States, saying in a statement, "We will further build on this foundation as we continue to keep our people safe and healthy from the impacts of the global COVID-19 pandemic, and work to advance peace and inclusion, economic prosperity, and climate action around the world."
Three advisers to President Trump told CNN that his handling of the coronavirus was a massive factor in his election loss. A senior adviser said Trump's dismissive attitude and misinformation about the virus alienated senior voters who rejected the President's performance on Covid-19.
Only one state trending in the right direction
At least 41 states now report more Covid-19 infections than the previous week and only one state -- Tennessee -- is trending in the right direction, according to Johns Hopkins data.
Community transmission in the state is expanding, mainly from small household gatherings, Shah added. It's those gatherings that public health officials nationwide have warned are fueling the spread of the virus and could further drive the surge during the upcoming holidays.
Illinois health officials reported 10,376 new cases Friday, a new daily high and the first time the state has reported more than 10,000 daily infections.
In a news release Friday, Colorado health officials said the newest Covid-19 model indicates state hospitalizations are increasing more sharply than last week's projections. Keeping hospitals below demand capacity "will require substantial and rapid action to prevent transmission," the release said
Colorado has reached its highest number of Covid-19 hospitalizations, exceeding its April peak, the officials said.
"We reached this even faster than the modeling predicted," officials said. "If the epidemic curve is not bent, Colorado could surpass intensive care unit (ICU) capacity in late December instead of January as reported in last week's modeling report."
In Ohio, the governor said Friday the state saw 5,008 new infections, the highest number of cases recorded in a 24-hour period. The climbing numbers are likely to trigger new mandates, he said.
"When we see our hospitals starting to fill up," Gov. Mike DeWine said, "the orders we will have to implement when it really gets dire will be uniform throughout Ohio."
More measures announced
In some parts of the country, new orders have already arrived.
They include instructions to stay home between 10 p.m. and 5 a.m., a news release from the governor's office said earlier this week.
Baker said he also tightened previous gathering restrictions. Gatherings in private residences are now limited to 10 people indoors and 25 people outdoors, he said.
"We know we're asking a lot here," Baker said. "And it comes on top of asking a lot of employers and residents for many months now with the virus. As we've said before, it isn't going anywhere, and until there's a vaccine or medical breakthrough, it's us against the virus."
In Denver, a 10 p.m. curfew for residents and non-exempt businesses begins Sunday, officials said Friday.
"We're on a very dangerous path," Mayor Michael Hancock said. "Across the state, including here in the Denver area, hospitalizations have increased over 40% in just the last week."
Officials have scheduled 10 "mass testing events" in South Dakota, which reported 28 deaths on Friday, a record number of deaths in a single day for the state.
The state Department of Health, along with the South Dakota National Guard, Office of Emergency Management and the US Department of Health and Human Services, will hold drive-thru testing events in Aberdeen, Chamberlain, Custer, Madison, Martin, Mobridge, Pierre, Spearfish, Watertown, and Yankton, the department said in a news release.
Earlier social distancing could have saved 59,000 Americans
Meanwhile, a new modeling study published Friday shows more than 1 million US infections and more than 59,000 deaths could have been prevented by early May if mitigation steps had been implemented two weeks earlier.
Sen Pei, a research scientist in the Columbia University Mailman School of Public Health, and colleagues built a Covid-19 transmission model that looked at all US counties from February 21 through May 3.
Broad Covid-19 transmission control measures were announced March 15, the team wrote.
The study found that beginning such interventions two weeks earlier -- on March 1 -- could have resulted in more than 1 million fewer confirmed cases and more than 59,000 fewer deaths.
"Our results demonstrate the dramatic impact that earlier interventions could have had on the COVID-19 pandemic in the US," the authors wrote. "Looking forward, the findings underscore the need for continued vigilance when control measures are relaxed."
What's needed to control a rebound of Covid-19 outbreaks, they wrote, is rapid detection of increasing case numbers and quick re-implementation of control measures.
Study describes how Delaware reduced its infections and deaths
Leading experts have also highlighted the importance of quick and stringent mitigation measures, and a newly published study backs their points.
Delaware's state-mandated Covid-19 mitigation efforts and investigations dramatically reduced the number of Covid-19 cases, hospitalizations and deaths earlier this year, according to a study published Friday in the US Centers for Disease Control and Prevention's Morbidity and Mortality Report.
The first Covid-19 case in the state was identified March 11, and officials immediately went to work to manage the pandemic, starting by investigating all identified cases. Nearly two weeks later, the state issued a stay-at-home order lasting through June 1.
By late April, there was a statewide mask mandate. By mid-May, the state started broader contact tracing.
Looking at cases through June, it appears those steps were the right ones.
From late April through June, the incidences of Covid-19 declined by 82%, hospitalizations dropped by 88% and mortality fell by 100%.
"Masks are critical for reducing SARS-CoV-2 transmission from persons with symptomatic or asymptomatic infection," the report said. "Early detection, self-isolation, and investigation of Covid-19 cases and self-quarantine of close contacts can be effective in preventing transmission, if contacts are identified and reached soon after exposure."
