Frontiers in Pediatrics and Child Health covers the full continuum of child health, publishing studies that advance early-life diagnostics and NICU care, improve sepsis and trauma management in critical settings, and harness digital-health and AI tools for tele-paediatrics and predictive decision-support. The journal spotlights child-sized device and drug-delivery innovations, precision-medicine breakthroughs in genomics and rare diseases, and evidence that strengthens infectious-disease control and vaccinology. It also welcomes work on neurodevelopment, adolescent mental-health technologies, and public-health or policy research aimed at closing global equity gaps in paediatric care.
