[Endemic enterovirus meningitis in 4 newborn infants]
Summary
Enteroviruses caused meningitis in four infants in a single maternity ward. Despite mild symptoms, cerebrospinal fluid analysis revealed significant inflammation, indicating a potential public health concern in neonatal units.
Area of Science:
- Neonatal infectious diseases
- Virology
- Pediatric neurology
Background:
- Meningitis in infants can present with subtle symptoms.
- Enteroviruses are common viral pathogens.
- Nosocomial infections in maternity units require careful monitoring.
Observation:
- Four infants in the same maternity unit developed meningitis within a ten-day period.
- Clinical presentation was mild, with low-grade or short-lived fever.
- Standard infection markers (sedimentation rate, leukocyte count, C-reactive protein) were not indicative of bacterial infection.
Findings:
- Cerebrospinal fluid analysis in three infants showed marked pleocytosis (2660-5000 cells/µL), predominantly granulocytes.
- Enteroviruses were identified as the causative pathogens.
- Mildly symptomatic family members and asymptomatic neonates carried the same enteroviruses, suggesting transmission routes.
Implications:
- Enteroviral meningitis can mimic milder viral illnesses in neonates, complicating diagnosis.
- The findings highlight the risk of enterovirus transmission within maternity settings.
- Prompt identification and infection control measures are crucial to prevent outbreaks in neonatal populations.
