U.S. nears 500,000 COVID-19 deaths as experts say it s critical to keep up safety measures
"It s something that is historic. It s nothing like we ve ever been though in the last 102 years since the 1918 influenza pandemic ," said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases.

"It really is a terrible situation that we ve been through and that we re still going through. And that s the reason why we keep insisting to continue with the public health measures -- because we don t want this to get much worse than it already is."

from COVID-19 in the US, according to Johns Hopkins University.

And another 91,000 Americans are projected to die from the disease by June 1, according to the University of Washington s Institute for Health Metrics and Evaluation.

Decreases in new COVID-19 cases and hospitalizations in recent weeks have prompted some state and local leaders to loosen restrictions .

But as new coronavirus variants spread, health experts say it s to prevent yet another catastrophic surge.

"The most uncertain driver of the trajectory of the epidemic over the next four months is how individuals will respond to steady declines in daily cases and deaths," the IHME team wrote.

"More rapid increases in mobility or reductions in mask use can easily lead to increasing cases and deaths in many states in April."

Several new concerning variants of coronavirus have been found in the U.S., including the highly contagious B.1.1.7 strain first detected in the U.K.

The Centers for Disease Control and Prevention has projected a " rapid growth " of the B.1.1.7 strain across the U.S., saying it will likely become the predominant variant in the country by March.

The IHME team said while the B.1.1.7 strain likely accounts for less than 20% of coronavirus infections now, that number could jump to 80% by late April.

That s why experts say the U.S. should also ramp up its testing: not just to track infections and antibodies, but also variants.

"We have been behind on testing from day one," Kathleen Sebelius, former Health and Human Services Secretary, said Saturday.

She said the U.S. needs to "focus on both testing that we need to identify who has the disease, and then the serology tests that will tell us more about antibodies and what kind of variant is circulating."

While vaccinations are ongoing, it s unlikely they ll help the U.S. reach herd immunity levels any time soon.

So far, more than 42.8 million Americans have received at least the first dose of a COVID-19 vaccine, according to CDC data.

More than 17.8 million people have been fully vaccinated. That s about 5.5% of the U.S. population.

Herd immunity is reached when the majority of the population becomes immune to an infectious disease -- either through infection and recovery or through vaccination.

Fauci estimates between 70% to 85% of the U.S. population needs to be immune for herd immunity to take effect against the virus.

The IHME team wrote they do not expect the country will reach herd immunity before next winter.

"The model suggests that we should have a quiet summer," IHME Director Dr. Chris Murray told CNN Friday. "But we know Covid s really seasonal, so when the next winter rolls around, we need to have a much higher level of protection to stop Covid in its tracks than we re likely to achieve."

To speed up getting at least the first doses into arms, the US should consider delaying the second dose of vaccines, another expert said.

"Everybody needs a second dose, there s no question about that," Dr. Ashish Jha, dean of the Brown University School of Public Health, said Friday. "I think the question is, right now we wait four weeks between first and second dose. What if we went six weeks or eight weeks or 10 weeks -- not much longer than that."

His comments came the same day two top U.S. officials -- Andy Slavitt, senior adviser to the White House COVID-19 response team and Fauci -- said they don t think the U.S. should delay or skip second vaccine doses. Jha says his suggestion is middle ground to vaccinate more high-risk people quickly.

Amid ongoing challenges for vaccinations and concerns of another case uptick, local leaders are also working to navigate what a safe return to class looks like.

School reopening guidelines focus on five key COVID-19 mitigation strategies: the universal and correct wearing of masks; physical distancing; washing hands; cleaning facilities and improving ventilation; and contact tracing, isolation and quarantine.

Vaccine and testing are "additional layers" of protection, the agency said.

On Friday, CDC Director Dr. Rochelle Walensky told a White House briefing that with those strategies, schools may open no matter how much virus is spreading within a community.

"There are opportunities for in-person learning at all stages of ... community spread," Walensky said. "I would actually invite schools to lean in and to look at what is needed ... to try and get more and more children back to school."

Randi Weingarten, the president of the American Federation of Teachers, told CNN Saturday the agency s guidelines are a "safety guard rail" for teachers -- and in a recent poll, most educators said they d be comfortable returning to class with the help of testing, vaccine prioritization and mitigation strategies in place.

But so far, have started allowing all or some teachers and school staff to receive the vaccine.

And schools face another challenge when it comes to reopening for in-person instruction, Weingarten added.

When schools do put some of those measures in place, including smaller class sizes and social distancing, they need more space and more educators, Weingarten, said.

"The reason that you have so many places that are in hybrid is because they don t have the space and they don t have the educators," she said. "The real issue right now is how do we help take the places that are on remote and turn it around."
