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

More than 614,000 Americans have died from COVID-19 and over 4.2 million people have died worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.

Just 58.2% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.

The CDC last week, citing new science on the transmissibility of the delta variant, changed its mask guidance to now recommend everyone in areas with substantial or high levels of transmission — vaccinated or not — wear a face covering in public, indoor settings.

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

As of Wednesday, 62.58% of Texas residents 12 and older have received at least one shot, according to the state health department.

Hundreds of students, school staff quarantined in Arkansas district

Hundreds of student and staff members from the Marion School District in Arkansas are now quarantined in only the second week of the school year, officials announced.

The state has a ban on school districts imposing a mask mandate.

On Tuesday, the district said 253 students would begin their two-week quarantine due to 15 cases that were reported in the schools. This came after 168 students were already quarantined last week.

“If all students and teachers had been wearing a mask appropriately- then today’s 15 positive cases would be isolated- but there would be no resulting quarantines for anyone else,” the district said in a statement.

Arkansas Gov. Asa Hutchinson told reporters Tuesday he regretted signing the bill that banned masks in schools and urged the state legislature to amend the law to give schools the option.

Florida school district says 2 employees dead from virus, pushes mask mandate

A Florida school district that defied Gov. Ron DeSantis’ ban on school mask mandates said Tuesday that two of its employees died from the virus last weekend.

Carlee Simon, the superintendent for the Alachua County Schools, said in a statement that the district “is experiencing this spike first-hand.”

“Over the weekend two of our employees passed away from COVID,” she said in a statement. “We’ve had 18 new cases in the last three days alone. More than 80 employees are now in quarantine, and that number is rising fast.”

The school district, which includes which includes Gainesville, voted Tuesday night to issue a mask mandate for students and staff for the next two weeks. The mandate will be reevaluated on Aug. 17, Simon said.

Hawaii issues vaccine mandate for middle, high school athletes

The Hawaii State Department of Education announced that all middle and high school athletes, athletic staff and volunteers will need to be fully vaccinated by Sept. 24 in order to participate in activities.

The rule affects students who are eligible for the vaccines, meaning they must be over 12.

“This decision was not made lightly because we know the important role athletics play in a well-rounded education, but we cannot jeopardize the health and safety of our students and communities,” interim Superintendent Keith Hayashi said in a statement.

The start of the athletic season was delayed to Sept. 24 due to the state’s rising positivity rate, according to the department.

This is the first state to require vaccinations for its student athletes.

Illinois governor issues mask mandate for schools

Illinois Gov. JB Pritzker announced Wednesday that all pre-K through 12th grade schools and day cares must follow universal masking indoors regardless of vaccination status.

Pritzker said the state is facing a growing threat from the delta variant and noted that children under 12 aren’t yet eligible for COVID-19 vaccines.

“Far too few school districts have chosen to follow the federal Centers for Disease Control and Prevention prescription for keeping students and staff safe,” he said at a news conference. “Given the CDC’s strong recommendation, I had hoped that a state mask requirement in schools wouldn’t be necessary, but it is.”

Surge pushing hospital staffing to breaking point

The latest delta surge is once again pushing hospital staffing to breaking points across the U.S.

In Alaska, Idaho, Oregon and Washington, some “facilities are experiencing substantial shortages of both clinical and support staff,” according to a Department of Health and Human Services planning document obtained by ABC News Wednesday.

In hard-hit Missouri, many hospitals “don’t have the staff to support a surge without further modification to operational strategies,” the document said.

At a Shreveport, Louisiana, hospital, where the number of COVID-19 patients are multiplying, nurse Melinda Hunt told ABC News, “To be honest, I probably cry most days at work. And I cry at home. I’m tired. I’ve been doing this a year and half. It feels like it’s never going to end.”

WHO chief: No booster shots until at least end of September

The World Health Organization is calling for a moratorium on booster shots until more people from low-income countries have received a vaccine.

Low-income countries have only been able to administer 1.5 shots for every 100 people due to lack of supply, Dr. Tedros Adhanom Ghebreyesus, WHO Director-General, said Wednesday.

A moratorium on boosters until at least the end of September will “enable at least 10% of the population of every country to be vaccinated,” he said.

But White House press secretary Jen Psaki said in response that the U.S. doesn’t have to choose.

“We feel that it’s a false choice and that we can do both,” Psaki said Wednesday.

The U.S. has ordered enough supply for every American to get vaccinated, plus get a booster shot, according to the White House. The U.S. has already pledged to donate 580 million doses to the international community by 2022.

Fully vaccinated people susceptible to ‘long COVID’: Fauci

Dr. Anthony Fauci is warning that fully vaccinated people are also susceptible to “long COVID” if they have a breakthrough infection.

“We already know that people who get breakthrough infections and don’t go on to get advanced disease requiring hospitalization, they too are susceptible to long COVID,” Fauci told McClatchy. “You’re not exempt from long COVID if you get a breakthrough infection.”

As the delta variant surges, Fauci said, “there could be a variant that’s lingering out there that can push aside delta.”

“If another one comes along that has an equally high capability of transmitting but also is much more severe, then we could really be in trouble,” he said.

The Offspring drummer says he’s not playing at upcoming shows because he’s unvaccinated

Pete Parada, the drummer for pop-punk band The Offspring, says he is not playing with the band at upcoming shows because he is unvaccinated.

Parada wrote on Instagram that he’s avoiding the shot on his doctor’s advice, saying he’s had a lifelong battle with the rare neurological disorder Guillain-Barré syndrome and the vaccine’s “risks far outweigh the benefits.”

Because he’s unvaccinated, “it has recently been decided that I am unsafe to be around, in the studio, and on tour,” Parada said.

“I have no negative feelings towards my band,” he continued. “They’re doing what they believe is best for them, while I am doing the same.”
