Rotavirus infections in high-risk neonates

Area of Science:

• Neonatal Medicine
• Virology
• Infectious Diseases

Background:

• Rotavirus is a common cause of gastroenteritis in infants.
• Neonatal intensive care units (NICUs) are high-risk environments for pathogen transmission.

Purpose of the Study:

• To determine the incidence and risk factors of rotavirus infection in neonates admitted to a referral nursery.
• To assess the clinical presentation and shedding patterns of rotavirus in infected neonates.
• To provide recommendations for rotavirus detection in NICUs.

Main Methods:

• Weekly surveillance for rotavirus infection in 260 neonates over 12 months.
• Clinical data collection including birth weight, feeding method, and length of stay.
• Stool sample analysis for rotavirus detection.

Main Results:

• 15.4% of neonates tested positive for rotavirus.
• Diarrhea was present in one-quarter of infected neonates.
• Low birth weight and longer hospital stay were associated with increased rotavirus risk.
• Breastfed neonates had a lower incidence of rotavirus infection compared to formula-fed neonates.
• No seasonal variation in infection rates was observed.

Conclusions:

• Rotavirus infection is prevalent in neonatal nurseries and associated with specific risk factors.
• Breastfeeding appears to be a protective factor against rotavirus infection in neonates.
• Routine rotavirus detection in neonates presenting with diarrhea in NICUs is recommended.
