(NEW YORK) — The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.

More than 618,000 Americans have died from COVID-19 and over 4.3 million people have died worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.

Just 58.8% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.

Here’s how the news is developing Thursday. All times Eastern:

Florida, Hawaii, Louisiana, Mississippi reporting most cases ever

Biden says he stands with officials defying state mandates barring masks in schools

President Joe Biden said he stands with the local leaders in Texas and Florida who are implementing masks in classrooms despite orders from their governors banning mask mandates in schools.

“To the mayors, school superintendents, educators, local leaders, who are standing up to the governors politicizing mask protection for our kids, thank you,” he said Thursday. “Thank God that we have heroes like you. And I stand with you all, and America should as well.”

Florida has more cases than 30 states combined

In the last week, “Florida has had more COVID-19 cases than all 30 states with the lowest case rates combined,” White House COVID coordinator Jeff Zients said at Thursday’s White House briefing.

He added, “Texas alone have accounted for nearly 40% of new hospitalizations across the country.”

But the surge is driving up vaccinations and he said the most significant vaccine progress is in states with the most COVID-19 cases.

“In the past month, we’ve nearly tripled the average number of shots each day in Arkansas and quadrupled in Louisiana, Alabama and Mississippi,” Zients said.

Largest teacher’s union in US supports vaccine requirements for educators

The National Education Association, the largest teacher’s union in the U.S., has announced support for COVID-19 vaccine requirements or regular testing for teachers.

NEA President Becky Pringle said in a statement, “As we enter a new school year amidst a rapidly spreading Delta variant and lagging public vaccination rates, it is clear that the vaccination of those eligible is one of the most effective ways to keep schools safe, and they must be coupled with other proven mitigation strategies.”

Nearly 90% of NEA members say they’re fully vaccinated, the union said.

Some HHS employees will be required to be vaccinated

Going a step beyond the general guidelines for the federal workforce — which is to get vaccinated or be subject to masking/testing — the Department of Health and Human Services is offering only one option for its patient-facing employees: get vaccinated.

The 25,000 HHS employees who will be required to get vaccinated are concentrated within the Indian Health Service and National Institute of Health, as well as the U.S. Public Health Service Commissioned Corps.

The deadline to get vaccinated is the end of September, according to an HHS official familiar with the plan. There will be exemptions for religious or medical reasons.

Fauci talks booster shots

The Food and Drug Administration is poised to authorize a third COVID shot for the immunocompromised on Thursday, sources told ABC News.

About 3% of the population would qualify, Dr. Anthony Fauci told ABC News’ “Good Morning America.”

He said the boosters would be “for example, people who have transplantation and are on immunosuppressive drugs for that; people on therapy for cancer — cancer chemotherapy; people with advanced HIV disease; and people who are receiving immune suppressive therapy for a variety of diseases.”

When asked if the boosters would be available to everyone, Fauci said, “You have to follow people, which we’re doing in real-time, mainly a non-immune compromised, either an elderly person or a younger person … to determine if their level of protection goes below a critical level.”

He added, “If and when it does, and it’s likely that it will because no vaccine is gonna last forever, we’re gonna be ready and have a plan to give those individuals the additional dose they might need.”

4 Georgia school districts pause in-person learning

Four school districts in Georgia recently paused in-person learning as positive cases of the coronavirus among staff and students swelled in the first days of school this month.

The districts — Macon, Taliaferro, Glascock and Talbot — account together for less than 1% of Georgia’s 1.7 million students, but the need to shut down in-person learning so early in the school year worries district officials.

“The difference now in this outbreak that we see than the outbreak that happened last school year is that this seems to be more centered on kids rather than adults, so that scares me to death,” Jack Catrett, the superintendent of schools in Talbot County, told Columbus ABC affiliate WTVM.

Talbot County, which had 11 students test positive on Friday, shut its doors to students for one week, with kids returning Monday. The other three districts have planned for two-week pauses to in-person learning.
