Clinical characteristics of pediatric patients with COVID-19 between Omicron era vs. pre-Omicron era.

ABSTRACT:

Introduction

Detailed data on clinical characteristics in children with the omicron strain of SARS-COV-2 are limited.

Methods

We conducted a retrospective observational study of children with COVID-19 at the National Center for Child Health and Development to evaluate the clinical manifestations during and before the emergence of the omicron variant. Only symptomatic patients without underlying diseases were included. Participants were divided into two temporal groups: the "omicron era" (1/2022-2/2022) and the "pre-omicron era," where the delta variant predominated (7/2021-11/2021). The patients were subclassified into an older vaccine-eligible group (aged 12-17 years), a younger vaccine-eligible group (aged 5-11 years), and a vaccine-ineligible group (aged 0-4 years).
