Infants Who Were Exposed to COVID-19 in the Womb Show Neurodevelopmental Differences
As the COVID-19 pandemic unfolded, scientists began tracking how the virus impacted not only infected individuals but also unborn babies. Recent research reveals that infants exposed to COVID-19 in the womb may experience neurodevelopmental differences during their first year of life. These findings have prompted growing concern among healthcare professionals and expecting parents alike.
In this article, we explore what current studies suggest about prenatal exposure to COVID-19, the possible developmental delays, early signs parents should watch for, and how to promote healthy infant development during and after the pandemic.
Meta Description:
Learn how COVID-19 exposure during pregnancy may impact infant brain development. Explore symptoms, risks, and prevention for expecting mothers.
Understanding Prenatal COVID-19 Exposure
When a pregnant woman contracts COVID-19, the virus may influence the intrauterine environment. Although the virus itself rarely crosses the placenta, the inflammation and immune response it triggers can impact foetal development.
Studies from academic centres like Columbia University and Massachusetts General Hospital have noted that babies exposed to maternal COVID-19 in the womb had slightly lower scores on developmental screening tests at 6 and 12 months compared to those not exposed.
What Neurodevelopmental Differences Have Been Observed?
The most common areas where differences were noted include:
- Motor Skills: Slight delays in crawling or sitting.
- Social Engagement: Reduced eye contact or limited facial expressions.
- Communication: Fewer vocalisations or gestures.
While these differences were not always clinically significant, they did show a consistent trend among exposed infants.
What Causes These Differences?
The exact mechanisms are still under investigation, but researchers point to a few probable causes:
- Maternal immune activation: Inflammation caused by the mother’s response to the virus may interfere with foetal brain development.
- Placental dysfunction: COVID-19 can affect placental health, reducing oxygen or nutrient flow to the baby.
- Stress and mental health: Maternal stress due to illness or pandemic-related anxiety can impact the baby’s development.
What Parents Should Look Out For
Early detection of developmental delays is crucial. Parents should speak to a paediatrician if their baby:
- Doesn’t smile by 3 months
- Doesn’t respond to sounds or voices
- Has difficulty holding their head up or rolling over
- Doesn’t babble or coo by 6 months
These signs don’t always mean there is a problem, but early intervention is key if delays are confirmed.
Can the Effects Be Prevented or Reversed?
Yes, in many cases. Early stimulation, responsive parenting, and timely developmental support can significantly improve outcomes. Here are key recommendations:
- Regular paediatric check-ups to monitor milestones
- Engage in sensory play – let the baby touch different textures and see colours
- Talk and sing to your baby daily to encourage communication
- Respond quickly to cries and needs, building trust and bonding
Expert Insights
Dr. Dani Dumitriu from Columbia University emphasised that the observed delays are mild and may resolve with age and stimulation. “These differences are subtle,” she said, “but highlight the need for continued monitoring of pandemic-exposed children.”
Should You Be Worried If You Had COVID-19 During Pregnancy?
Not necessarily. Most babies exposed to COVID-19 in the womb still develop typically. However, it's essential to be vigilant and proactive.
Be sure to schedule regular developmental screenings and seek help if you observe any red flags.
Role of Public Health and Awareness
Post-pandemic maternal and child health support must include monitoring for COVID-related developmental risks. Awareness campaigns and support programs can help families access early interventions.
Organisations like the CDC and WHO have issued guidance on monitoring infant health after COVID exposure during pregnancy.

Conclusion
While more research is needed, early findings suggest that COVID-19 exposure during pregnancy could mildly affect infant development. Fortunately, with awareness, timely detection, and nurturing care, these children can thrive just like their peers. If you were pregnant during the pandemic, staying alert and seeking paediatric guidance is a wise step forward.
FAQs
Q. Can COVID-19 cross the placenta and infect the baby?It is rare. Most cases involve inflammation or stress impacting development rather than direct infection.
Q. What age should I be most concerned about developmental milestones?Key periods include 3 months, 6 months, and 12 months. Track milestones closely during the first year.
Q. Should I get my baby tested if I had COVID-19 during pregnancy?There’s no routine test for COVID-exposure effects. But a developmental assessment is strongly advised.
Q. What if my baby was born preterm due to COVID-19?Prematurity itself can cause delays. Your doctor may recommend early intervention and more frequent monitoring.
