The increase in hospital admissions for or with COVID-19 is greater for children than for the population overall. In the
most recent week, 54% of children ≤ 18 years admitted had no comorbidities and 70% were symptomatic.
During December 26, 2021 – January 1, 2022, among the 41% of children admitted with but not primarily for COVID-19,
the most common reasons for admission were acute and chronic medical conditions. COVID-19 may have been an
exacerbating factor contributing to the need for hospitalization, but the significance of the COVID-19 diagnosis cannot
be determined from these data. Statewide, injury or trauma represented 2.1% of admissions with COVID-19 (only 12 out
of the 571 admissions that week).
The large increases over time have been observed for children admitted both for COVID-19 and for other reasons, but
with a positive COVID-19 result. In this time-period, New York City saw an 18-fold increase in admissions for COVID-19
(227 vs. 12) and 15-fold increase in admissions with COVID-19, but primarily for other reasons (158 vs. 10).
Analyses suggest the relatively greater increases in hospitalizations for children may be due to reduced vaccine coverage
combined with modestly reduced vaccine effectiveness against hospitalization for children 5-17 years, and the absence
of vaccines for children 0-4 years. Likewise, preliminary analyses suggest potential increased severity of the Omicron
variant may also play a role in increasing rates of hospitalizations for children ≤11 years, relative to adults and children
12-17 years.
Notably, among children admitted to the hospital for or with COVID-19 during the week of December 20-26, 2021,
• 4% of 5 to 11 year olds were vaccinated and 91% were unvaccinated
• 26% of 12 to 17 year olds were vaccinated and 65% were unvaccinated. |
