Data showed that seroprevalence of the infection-induced antibodies increased among all age groups between September 2021 through February 2022, up from 34% in December to 58% by the end of February. The largest increase in antibodies was spotted among individuals younger than 17 years old. CDC officials on Tuesday said around 75% of both children and teens had infection-induced antibodies.
The vast majority of cases identified by the CDC since late last year have been caused by various strains of the omicron variant of COVID-19. The BA.1 subvariant of omicron was responsible for a case surge early this year, but officials say the BA.2 variant – colloquially known as the “stealth variant” of omicron – makes up around 68% of the circulating virus right now.
“I didn't expect it to increase quite as much but we follow the data and we look at the data and this is what the evidence is showing us and so this is why we want to get this message out to the U.S. population as soon as possible,” Clark said. “This is the first time the population's seroprevalence is over 50 percent.”
