The CDC analyzed samples from children between the ages of six months and 17 years who had blood drawn at commercial labs for non-COVID tests in May and June. The CDC estimates 84.5% of Iowa children had COVID or were recovering from an infection in late spring.
Having had COVID indicates a person likely has antibodies against the virus that prevent reinfection. A UCLA study of mild cases of COVID has found antibodies against COVID drop during the first three months and disappear after a year. The Mayo Clinic’s website shows the number of daily cases of COVID in Iowa has been dropping since the end of July.
The CDC estimates just under 80% of U.S. children had COVID or were recovering from an infection this spring. An earlier estimate from the agency indicated that by the end of April about 60% of U.S. adults either had an active case of COVID or had recovered from one recently.
