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

More than 616,000 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 58.7% of Americans ages 12 and up are fully vaccinated against COVID-19, according to data from the Centers for Disease Control and Prevention.

‘This is not your grandfather’s COVID,’ pediatrician warns

Children with COVID-19 used to make up 1% of patients hospitalized at Children’s Hospital New Orleans. Now they account for about 20%, Dr. Mark Kline, physician-in-chief at Children’s Hospital New Orleans, told Good Morning America Monday.

He said about half of the children hospitalized are under 2 years old. Most of the others are between 5 and 10 years old, so too young to be vaccinated.

“This is not your grandfather’s COVID,” Kline said. “This delta variant is an entirely new and unexpected challenge.”

Dr. Peter Hotez, dean for the National School of Tropical Medicine at Baylor, warned on MSNBC that with “schools act[ing] as an accelerant, you should assume we’re going to see pediatric intensive care units all across the South completely overwhelmed and even a possibility of small tent cities of sick adolescents and kids.”

Hotez said parents need to know that “delta is something different” and “picking off young people like we’ve never seen.”

“If your adolescent kid is unvaccinated, you should assume there’s a high likelihood that that child is going to get COVID,” he said, adding, “And we haven’t even gotten to the ‘long COVID’ discussion around young people and what that means for their long-term cognitive health.”
