Insights

Acute gastrointestinal infections (AGIs) in children are common. This study analyzed five years of data, finding common pathogens and trends in detection rates, with most increasing until 2019 before declining in 2020.

Area of Science:

  • Pediatric infectious diseases
  • Clinical microbiology
  • Epidemiology

Background:

  • Acute gastrointestinal infections (AGIs) and diarrheal diseases significantly affect children globally.
  • Understanding the epidemiology of AGIs in pediatric populations is crucial for effective public health strategies.

Purpose of the Study:

  • To characterize the clinical and epidemiological features of pediatric patients with AGIs.
  • To analyze pathogen detection rates and trends using the BIOFIRE® FILMARRAY® Gastrointestinal Panel.

Main Methods:

  • Retrospective analysis of 17,611 stool samples from 12,783 pediatric patients (2016-2020).
  • Utilized the BIOFIRE® FILMARRAY® Gastrointestinal Panel for pathogen detection.
  • Employed Poisson and logistic regression to assess trends and risk factors.

Main Results:

  • 47.3% of tested stool samples were positive for at least one pathogen.
  • Commonly detected pathogens included Enteropathogenic Escherichia coli, Clostridioides difficile, and norovirus.
  • Annual pathogen detection rates generally increased from 2016-2019, with a decline in 2020.

Conclusions:

  • The study provides a comprehensive 5-year overview of AGI pathogen detection in children.
  • Identified key pathogens and temporal trends in detection rates.
  • Highlights the need for ongoing surveillance of pediatric AGIs.
