When do children avoid infection risks: Lessons for schools during the COVID-19 pandemic

Area of Science:

• Pediatric Public Health
• Developmental Psychology
• Infectious Disease Epidemiology

Background:

• School closures due to COVID-19 significantly impacted student learning and family routines.
• Maintaining in-person learning is a priority, but pharmaceutical interventions may be delayed during novel outbreaks.
• Assessing children's understanding of infection risk and adherence to protective measures is crucial for public health strategies.

Purpose of the Study:

• To investigate the earliest age at which children develop an understanding of infection risk.
• To determine when children can effectively translate this understanding into protective actions.
• To inform age-appropriate strategies for engaging children in public health protocols.

Main Methods:

• Synthesis of published research on children's cognitive development and risk perception.
• Inclusion of new empirical data on children's understanding of infection.
• Analysis of children's ability to adhere to transmission-limiting behaviors.

Main Results:

• Identified specific age ranges for the development of infection risk comprehension in children.
• Demonstrated a correlation between understanding risk and the adoption of protective behaviors.
• Highlighted the variability in children's ability to implement safety protocols based on age and cognitive development.

Conclusions:

• Early childhood education on infection risk is vital for effective public health adherence.
• Age-appropriate engagement strategies are necessary to support children's participation in safety protocols.
• Further research is needed to optimize interventions for young children during infectious disease outbreaks.
