· Clinical studies of coronavirus disease 2019 (COVID-19) in infants should be supported by rigorous laboratory diagnostic criteria.
· Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spreads to infants similarly to other viral respiratory infections.
· Among infants ≤1 year of age beyond the immediate postpartum period, COVID-19 is relatively mild, but even the low risk of severe disease requires prevention.
· Comorbidities increase infection vulnerability and complications in infants.
· Clinical and laboratory data do not sufficiently distinguish COVID-19 from other respiratory viral infections.
· Coinfection with SARS-CoV-2 is uncommon among infants.
· Unique infection sequelae, including multi-inflammatory syndrome in children and neonates and long COVID require further study and refinement of diagnostic criteria.
· Infection control standards applied to mother-infant dyads should be tempered by standard preventive strategies, maternal input, accommodation potential, and overall safety.
· Maternal vaccination prevents disease in early infancy.

- Epidemiology and surveillance implications of community-acquired pneumonia in children
- Eui Jeong Roh, Jung Yeon Shim, Eun Hee Chung
- Clin Exp Pediatr. 2022;65(12):563-573. Published online October 17, 2022

The identification of the causative pathogens of community-acquired pneumonia and appropriate treatment and prevention can reduce mortality and the socioeconomic burden by reducing the medical expenses. The world has been in the coronavirus disease 2019 pandemic since 2020, and there is always a risk of continuous emergence and epidemic of new respiratory infectious diseases. Therefore, it is important to sustain a monitoring system for respiratory infectious diseases including pneumonia.

In this article, a systematic review of reported primary immunodeficiency disease (PID) cases in Korea was performed and we attempted to estimate the number of PID patients and healthcare costs for the first time in Korea. Our review revealed that Korean PID cases are greatly underreported in the literature based on health insurance. Physicians in the field and health care policymakers should be aware of the disease burden of PID.
