Fusobacterium on the Rise: A Decade of Otogenic and Beyond

Area of Science:

• Pediatric Infectious Diseases
• Microbiology
• Epidemiology

Background:

• Fusobacterium is an emerging pediatric pathogen causing diverse infections.
• Large-scale studies on pediatric Fusobacterium infections are limited.

Purpose of the Study:

• To assess the incidence, clinical features, complications, and outcomes of pediatric Fusobacterium infections.
• To analyze trends in pediatric Fusobacterium infections over a 13-year period.

Main Methods:

• Retrospective cohort study of children aged 0-18 years.
• Data collected from a tertiary pediatric hospital between 2010 and 2023.
• Statistical analysis including linear regression to identify trends.

Main Results:

• A 10-fold increase in Fusobacterium infection incidence observed over 13 years.
• Otogenic infections were most common (50.2%), followed by skin/soft tissue, intra-abdominal, and pharyngeal.
• Significant rise in Fusobacterium isolations affecting both otologic and non-otologic sites.

Conclusions:

• Pediatric Fusobacterium infections are rising and present with significant complexity and complications.
• Infections are predominantly otogenic but involve multiple body systems.
• Understanding the evolving epidemiology is crucial for optimizing diagnosis and management.
