Pediatric COVID-19 in Korea: Lessons and Strategies for Future Disease-X Preparedness

The coronavirus disease 2019 (COVID-19) pandemic has had distinct public health and societal impacts on children worldwidely, prompting calls to prepare for the next pandemic by incorporating children's needs. Republic of Korea's experience provides insights into pediatric-focused pandemic response. This review analyzes the impact of COVID-19 on children in Korea and evaluates the national response. This review encompasses the Korea Disease Control and Prevention Agency COVID-19 response white paper, National Medical Center response report, Ministry of Education and Seoul Metropolitan Office of Education white papers, focusing on pediatric data and policies. Key findings were supplemented with international studies on pediatric COVID-19 epidemiology, vaccination, and educational impacts. Children in Korea accounted for a substantial number of COVID-19 cases during omicron wave, yet severe outcomes remained rare. Surveillance adaptations included dedicated monitoring of pediatric multisystem inflammatory syndrome through antibody testing. The healthcare system rapidly adjusted to pediatric needs by allowing home isolation for mild cases and by permitting caregiver accompaniment during pediatric hospital isolation. Vaccine rollout for adolescents began in 2021 and for ages 5-11 in 2022, with an initial policy focusing on high-risk children and voluntary uptake for others. In the education sector, Korea implemented remote learning infrastructure, distributing devices and expanding internet access to bridge the digital divide. Korea's pandemic response illustrates the importance of pediatric-specific strategies: surveillance, child-friendly healthcare protocols, risk communication to improve vaccine acceptance, and treating schools and child services as essential infrastructure.
