Insights

Extremely preterm infants born before 24 weeks face high infection risks. Addressing knowledge gaps in infection prevention and management is crucial for improving survival rates in this vulnerable population.

Area of Science:

  • Neonatal Medicine
  • Infectious Diseases
  • Pediatrics

Background:

  • Infants born before 24 weeks' gestational age (extremely preterm) have unique health challenges.
  • Infections are a primary cause of illness and death in these infants.
  • Neonatal care advances have improved survival, but invasive bacterial and fungal infections remain critical threats.

Purpose of the Study:

  • To review the epidemiology, microbiology, and outcomes of bacterial and fungal infections in extremely preterm infants.
  • To identify knowledge gaps in infection prevention and management for this population.
  • To emphasize the need for better data and novel strategies.

Main Methods:

  • This study is a narrative review of existing literature.
  • It synthesizes information on infection patterns, causative agents, and clinical outcomes.
  • The review focuses on infants born before 24 weeks' gestational age.

Main Results:

  • Extremely preterm infants are highly susceptible to invasive bacterial and fungal infections.
  • These infections contribute significantly to morbidity and mortality despite advances in neonatal care.
  • Current data on infection epidemiology and management in this group is limited.

Conclusions:

  • Invasive infections pose a major threat to extremely preterm infants.
  • Significant knowledge gaps exist in understanding and combating these infections.
  • There is an urgent need for enhanced international data collection and innovative strategies to protect these vulnerable infants.
