Younger and Rural Children are More Likely to be Hospitalized for SARS-CoV-2 Infections

Area of Science:

• Pediatric Emergency Medicine
• Infectious Diseases
• Public Health

Background:

• Understanding SARS-CoV-2 hospitalization risk factors in children is crucial for targeted interventions.
• Previous research has not fully elucidated the impact of different viral variants and demographic factors on pediatric COVID-19 hospitalizations.

Approach:

• A retrospective study analyzed SARS-CoV-2 positive pediatric cases from May 2020 to April 2022 at Arkansas Children's Hospital.
• Logistic regression models identified patient characteristics associated with increased hospitalization odds across different infection waves (pre-Delta, Delta, Omicron).

Key Points:

• Children infected during pre-Delta and Delta waves were twice as likely to be hospitalized compared to Omicron cases.
• Infants under 1 year and rural children exhibited significantly higher hospitalization rates across all waves.
• Children with complex medical conditions had a nearly 15-fold increased likelihood of hospitalization.

Conclusions:

• SARS-CoV-2 variant waves and patient demographics significantly influence pediatric hospitalization risk.
• Younger age, rural residence, and pre-existing complex conditions are key indicators for severe outcomes in pediatric COVID-19.
• Public health strategies should consider these factors to mitigate severe illness and optimize resource allocation.
