More than 9 in 10 kids have survived at least one bout with COVID, the CDC estimates

More than 90% of children in the U.S. have survived at least one infection by SARS-CoV-2, the virus that causes COVID-19, based on data collected from commercial laboratories around the country through October.

The Centers for Disease Control and Prevention's new "seroprevalence" estimates, published Thursday, look at whether people have detectable antibodies in their blood from at least one prior COVID-19 case. They could still be at risk of reinfection from the new variants circulating this winter.

"The estimates do not necessarily show how many people have enough antibodies to protect them against reinfection, severe outcomes, and/or COVID-19-related complications," the CDC says.
