More than half a million children in the United States have been diagnosed with Covid-19 since the start of the pandemic, according to the American Academy of Pediatrics and the Children's Hospital Association.
The child cases are likely underreported, because the way data is collected is not consistent across states. Even then, children now represent nearly 10% of all reported cases in the US.
It's getting worse. The groups found that 72,993 new child cases were reported between August 27 and September 10, a 15% increase in child cases over two weeks.
And even though the vast majority of children have only mild symptoms after contracting Covid-19, a number of kids have suffered serious complications. Some have died.
Eli Lipman is one of the kids who has suffered from "long-haul" Covid-19. The 9-year-old has had a 100 degree fever every day for months, his dad Jonathan Lipman told CNN. Eli said he felt like "the day after you got smashed into a wall."
