Developmental impacts of perinatal infections

Area of Science:

• Pediatric infectious diseases
• Neurodevelopmental disorders
• Public health

Background:

• Perinatal infections are increasingly recognized for their potential long-term effects on child neurodevelopment.
• Recent research highlights specific viruses, including congenital cytomegalovirus, Zika virus, Chikungunya, and SARS-CoV-2, with documented neurodevelopmental impacts.
• Understanding these impacts is critical for early intervention and improved child outcomes.

Purpose of the Study:

• To review current knowledge on the neurodevelopmental consequences of specific perinatal infections.
• To synthesize findings related to congenital cytomegalovirus, Zika virus, Chikungunya, and SARS-CoV-2.
• To emphasize the importance of ongoing neurodevelopmental surveillance.

Main Methods:

• Literature review of recent publications on perinatal infections and neurodevelopment.
• Analysis of studies investigating neurodevelopmental outcomes in children exposed to specific pathogens.
• Synthesis of data on developmental delays, autism spectrum disorder, and cognitive performance.

Main Results:

• Congenital cytomegalovirus infection, particularly symptomatic cases, is linked to developmental delays and increased risk of autism spectrum disorder.
• Prenatal exposure to SARS-CoV-2 may be a risk factor for developmental delay, necessitating close monitoring.
• Congenital Zika virus exposure is associated with neurodevelopmental sequelae and increased mortality, even in normocephalic infants.

Conclusions:

• Perinatal and congenital infections significantly elevate the risk of impaired neurodevelopment in children.
• Comprehensive and close neurodevelopmental follow-up throughout childhood is essential for all infants affected by perinatal infections.
