Rise in severe strep cases in kids was really return to normal, CDC says
While a health alert warned doctors late last year about rising cases of severe strep in children, U.S. officials now say those numbers were actually a return to normal.
“Based on preliminary 2022 data, iGAS (invasive group A streptococcal) infections in children have returned to levels similar to those seen in prepandemic years,” the U.S. Centers for Disease Control and Prevention said in an updated notice.
IGAS, which is triggered by infection with strep A bacteria, is rare, but it can lead to organ failure and tissue damage.
“During the COVID19 pandemic, the United States had very low numbers of iGAS infections in children. This was likely due to the steps many people took during the pandemic to prevent the spread of respiratory diseases,” the CDC said.
Between 2010 and 2020, the United States reported an average of more than 10,000 invasive group A strep cases each year, federal data show. More than 1,000 died each year.
As with other early infections in recent months, including RSV and the flu, the iGAS cases were reported earlier in the season than is typical, increasing between September and November, CBS News reported.
Respiratory diseases could increase again, authorities noted. While flu A has been dominant, type B strains may show up next, CBS News reported.
“We often do see a later peak and increase of influenza B viruses after influenza A viruses have peaked. So it’s actually still unknown whether we’re going to see an increase in influenza B viruses,” the CDC’s Tim Uyeki said at Emory University last month, CBS News reported.
