Although new COVID-19 cases in children, as measured by the American Academy of Pediatrics and the Children’s Hospital Association, have remained fairly steady in recent months, data from the Centers for Diseases Control and Prevention suggest that weekly cases took a big jump in early January.
For the most recent week covered . New cases for the first 2 weeks of the year – 31,000 for the week of Dec. 30 to Jan. 5 and 26,000 during Jan. 6-12 – were consistent with the AAP/CHA assertion that “weekly reported child cases have plateaued at an average of about 32,000 cases ... over the past 4 months.”
The CDC data, however, show that new cases doubled during the week of Jan. 1-7 to over 65,000, compared with the end of December, and stayed at that level for Jan. 8-14, and since CDC figures are subject to a 6-week reporting delay, the final numbers are likely to be even higher. The composition by age changed somewhat between the 2 weeks, though, as those aged 0-4 years went from almost half of all cases in the first week down to 40% in the second, while cases rose for children aged 5-11 and 12-15, based on data from the COVID-19 response team.
Emergency department visits for January do not show a corresponding increase. ED visits among children aged 0-11 years with COVID-19, measured as a percentage of all ED visits, declined over the course of the month, as did visits for 16- and 17-year-olds, while those aged 12-15 started the month at 1.4% and were at 1.4% on Jan. 27, with a slight dip down to 1.2% in between, the CDC said on its COVID Data Tracker. Daily hospitalizations for children aged 0-17 also declined through mid-January and did not reflect the jump in new cases.
Meanwhile, vaccinated children are still in the minority: 57% of those under age 18 have received no COVID vaccine yet, the AAP said in a separate report. Just 7.4% of children under age 2 years had received at least one dose as of Jan. 25, as had 10.1% of those aged 2-4 years, 39.6% of 5- to 11-year-olds and 71.8% of those 12-17 years old, according to the CDC, with corresponding figures for completion of the primary series at 3.5%, 5.3%, 32.5%, and 61.5%.
