COVID-19 updates: 345 children currently hospitalized with coronavirus in Texas
That number was up from 282 on Thursday.
The United States is facing a COVID-19 surge this summer as the more contagious delta variant spreads.
More than 643,000 Americans have died from COVID-19 while over 4.5 million people have died from the disease worldwide, according to real-time data compiled by the Center for Systems Science and Engineering at Johns Hopkins University.
Just 61.7% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the U.S. Centers for Disease Control and Prevention.

Oscar De La Hoya hospitalized with COVID-19, will miss comeback fight
Hall of Fame boxer Oscar De La Hoya said on social media Friday he is hospitalized with COVID-19.
Due to his illness, he won't be able to fight former UFC champion Vitor Belfort on Sept. 11 in Los Angeles, which would have been De La Hoya's first bout since 2008.
"Preparing for this comeback has been everything to me over the last months, and I want to thank everyone for their tremendous support," De La Hoya, 48, said in an Instagram post, noting that he is fully vaccinated. "I am currently in the hospital getting treatment and am confident I will be back in the ring before the year is up. God bless everyone and stay safe."
Florida Governor appeals court ruling invalidating his ban on student mask mandates
Florida Gov. Ron DeSantis filed an appeal against a court ruling invalidating his ban on student mask mandates Thursday evening.
The governor had banned school districts from implementing mask mandates without a parent opt-out.
The move unleashed a stay of proceedings that enables the state to continue punishing districts, at least until Wednesday, when a judge will decide whether to vacate the stay.
In the meantime, school board members across the state could continue to lose their salaries if their schools set mask mandates -- a punishment given to board members in two counties and threatened to those in eight others.
The appeal comes a week after Judge John C. Cooper found that a blanket ban on face masks in schools "does not meet constitutional muster.”

1 out of 8 Americans has tested positive for COVID-19, 1 out of 510 Americans has died from the virus
The country’s COVID death toll has risen to more than 643,000 and the number of cases stands at 39.5 million, according to data from Johns Hopkins University.
That means 1 out of 8 Americans has tested positive for COVID-19 and 1 out of 510 Americans has died of the virus.
Heading into Labor Day weekend health experts are urging the public, especially the unvaccinated, to act responsibly as the delta variant continues to fuel infections.
Holidays have proven to be a catalyst for virus spread in the U.S.
Last summer, shortly after Labor Day, the U.S. fell into its most significant viral surge of the pandemic.
Between the week following last Labor Day and Thanksgiving alone, the nation's daily case average surged by more than 400%.

US administers highest number of vaccine doses since July
Over "1.40M doses reported administered over yesterday's total, including 550K newly vaccinated and 96K additional doses," White House COVID-19 data director Cyrus Shahpar said Friday.
That's the highest dose total since July 1, he said.
So far over 175 million people, or 61.9% of the eligible population, are fully vaccinated.
Pediatric hospitalizations nearly 4 times higher in states with low vaccination: CDC
Two studies to be published Friday found fewer pediatric hospitalizations among children and communities with higher vaccination rates, the director of the U.S. Centers for Disease Control and Prevention said.
In one study, national data from August showed that children were nearly four times more likely to be hospitalized with COVID-19 in the states with the lowest vaccination rates when compared to states with the highest rates -- proof that "cocooning" children with vaccinated people keeps them safe, Dr. Rochelle Walensky said at a White House briefing Thursday.
The second study, which looked at hospitalizations rates in 12- to 17-year-olds across 14 states during July, found that adolescents who were unvaccinated were 10 times more likely to be hospitalized with COVID-19 than their fully vaccinated peers, Walensky said.
"Both studies, one thing is clear: cases, emergency room visits and hospitalizations are much lower among children and communities with higher vaccination rates," Walensky said. "We must come together to ensure that our children, indeed, our future, remain safe and healthy during this time."
