A Review of Pediatric Influenza

Influenza remains a significant public health concern, particularly among children. This comprehensive review focuses on pathophysiology, epidemiology, clinical presentation, treatment, and vaccines for pediatric influenza. Key genetic and immune-related factors, as well as excessive neutrophil activation, contribute to severe disease and outcomes. Epidemiologically, influenza affects 8% to 10% of children in the United States annually, with higher hospitalization rates among children who are Black, Hispanic, Native American and Alaska Native, and Asian and Pacific Islander. Clinically, children exhibit more severe symptoms and higher rates of gastrointestinal manifestations compared with adults. Treatment primarily involves neuraminidase inhibitors, like oseltamivir; although, therapies, such as baloxavir marboxil, are also effective. Vaccination remains the cornerstone of prevention, yet declining rates of uptake and increasing vaccine hesitancy pose challenges for population immunity. Universal influenza vaccine research offers hope for broader protection. This review aims to inform evidence-based practices in managing pediatric influenza and highlights areas for future research.
