(CNN) As Covid-19 cases continue to jump during the fall surge, Dr. Anthony Fauci says there's little chance of normalcy on the horizon.
The US will have a vaccine in the next few months, but there's a chance a "substantial proportion of the people" won't be vaccinated until the second or third quarter of 2021, Fauci said.
The director of the National Institute of Allergy and Infectious Diseases reiterated caution on the nation's outlook.
"I think it will be easily by the end of 2021, and perhaps even into the next year, before we start having some semblances of normality," Fauci said during a University of Melbourne panel discussion Tuesday.
Things aren't looking too good for the US as the winter approaches, he said Wednesday.
Twenty-nine states set new records this month for the most new daily cases since the pandemic began, according to data from Johns Hopkins University.
"We're not in a good place," Fauci during a virtual Q&A session on Wednesday. "Now we're averaging about 70,000 a (day). That's a bad position to be in."
And it's not just due to more testing. The average number of daily new cases this past week is up 21% compared to the previous week, according to JHU. But testing has increased only 6.63% over the same time frame, according to the Covid Tracking Project.
"We're rising quickly. If we just go back about six, seven weeks ago to Labor Day, we were at about 35,000 cases a day," said Dr. Ashish Jha, dean of Brown University School of Public Health.
"I would not be surprised if we end up getting to 100,000" new cases a day, Jha said.
At least 73,240 new US cases and 985 deaths were reported Tuesday, according to JHU.
The surge is hitting all regions of the country. As of Wednesday, 40 states were trending in the wrong direction, with at least 10% more new cases this past week compared to the previous week, according to JHU.
Missouri is the only state with at least 10% fewer cases, and the remaining nine states are relatively steady.

And with more cases come more hospitalizations and deaths.
This month, 11 states reported their highest single day of new deaths since the pandemic began.
And because a vaccine probably won't be available to most Americans until the middle of next year, personal responsibility will be key to saving American lives.
"If we continue our current behavior, by the time we start to go down the other side of the curve, a half a million people will be dead," said CNN medical analyst Dr. Jonathan Reiner, a professor of medicine at George Washington University.
There's no doubt masks make a difference, Fauci said.
"If you don't want to shut down, at least do the fundamental basic things, which are really the flagship of which is wearing a mask," Fauci said. "We can't have this very inconsistent wearing that you see, where you see some states that absolutely refuse to wear a mask."
Fauci added that the politicization of masks should stop.
"It almost becomes a political statement. We've got to get away from that," he said.
Under the current conditions, the daily US death toll is projected to reach 2,000 by January 1, according to the University of Washington's Institute for Health Metrics and Evaluation.
In the past nine months, more than 8.8 million people in the US have been infected with coronavirus, and more than 227,000 have died.
Even after setting up a field hospital at the state fairgrounds, Wisconsin is facing a dire predicament with hospital capacity.
"There is no way to sugarcoat it. We are facing an urgent crisis, and there is an imminent risk to you and your family," Gov. Tony Evers said.
In Ohio, admissions to intensive care units have doubled since the beginning of this month, Gov. Mike DeWine said.
Colorado is also worried about hospital capacity as the number of daily new cases skyrocketed this month.
"If these trends continue, it would exceed May hospitalization numbers," Gov. Jared Polis said.
"And the modeling suggests that if we don't change what we're doing, it'll exceed all of the existing hospital capacity by the end of the year. This thing moves quick, and we need to change the way we live."
The city and county of Denver has reduced the maximum allowed occupancy of restaurants, retailers and some other businesses from 50% to 25%, according to a statement Tuesday.
"Why we're doing this is to send a clarion call to everyone that we have a responsibility to once again put our hands on this boulder and begin to push it back up the hill," Denver Mayor Michael Hancock said.
Although 44 vaccines have made it to clinical trials, it might not be clear which works best -- or if any work at all -- until they have been authorized and distributed to many people, a team of experts said Tuesday.
"Protection against severe disease and death is difficult to assess in phase 3 clinical trials due to the unfeasibly large numbers of participants required," the experts, led by Dr. Susanne Hodgson of Oxford University's Jenner Institute, said in a review in The Lancet Infectious Diseases.
That data may only come "from large phase 4 trials or epidemiological studies done after widespread deployment of a vaccine," the experts wrote.
But if a vaccine is approved, officials said they will distribute it quickly -- though some Americans will have to wait longer than others.
"We'll distribute vaccines, accordingly, to all of America simultaneously," Army Gen. Gustave Perna, chief operating officer of the federal government's coronavirus response, said at an online event hosted by the conservative Heritage Foundation think tank.
"We will make sure that there is equitable distribution in accordance with that priority," he said. After that, states will "own the actual final distribution and administration down to individual arms."
Leaving vaccine distribution completely up to the states could lead to confusion and chaos, according to Kathleen Sebelius, who was Health and Human Services secretary under former President Barack Obama.
"The state-by-state approach is, you know, to put a fine point on it, is pretty nuts as far as I'm concerned," Sebelius said. "It leaves a ... high possibility of very inequitable distribution and kind of chaotic transportation to get to sites where you vaccinate."
Until a vaccine is available, experts say social distancing, wearing masks and staying in your select bubble of people are crucial to helping quash this pandemic.
