A clinical microbiologist has issued a strong warning about the risks of kissing newborns, highlighting how seemingly innocent affection can lead to life-threatening infections for vulnerable infants. The message, amplified recently by NHS surgeon Dr. Karan Raj on TikTok, has sparked widespread discussion, as many were unaware of the dangers.
A survey conducted by the UK charity The Lullaby Trust found that 54% of new and expectant parents allow friends and family to kiss their newborns, unaware of the serious risks posed to a baby’s health. But why exactly is kissing a baby so dangerous?
Vulnerable Immune Systems
A newborn’s immune system is not fully developed at birth, making them particularly susceptible to infections that are mild for adults but potentially devastating for babies. For the first three months of life, infants have fewer infection-fighting cells, such as neutrophils and monocytes, compared to adults.
This underdeveloped immune system means viruses and bacteria can cause severe illnesses in newborns. For example, the herpes virus—commonly known for causing cold sores in adults—can lead to severe complications in babies. If the virus spreads systemically, affecting the baby’s organs, it can even be fatal, especially during the first month of life.
Similarly, bacterial infections like group B streptococcus (GBS) and certain strains of E. coli pose significant risks. These bacteria, often harmless to adults, can cause sepsis, pneumonia, meningitis, and blood infections in newborns, with potentially serious outcomes.
How to Show Affection Safely
Parents are encouraged to set clear boundaries to protect their newborns, even if it feels uncomfortable. Asking visitors not to kiss or touch the baby’s face is a reasonable precaution. As the microbiologist notes, genuine care for a baby’s well-being should outweigh any momentary discomfort a visitor might feel.
For those who feel they must kiss the baby, there are safer alternatives:
- Wash hands thoroughly before contact.
- Avoid kissing the baby’s face or mouth; opt for the back of the head or feet instead.
- If you have cold sores, cover them with a dressing, and if you’re unwell, consider wearing a mask or avoiding the visit entirely.
A Small Sacrifice for Their Health
Newborns rely on those around them to keep them safe. While kissing a baby is often a gesture of love, it can unintentionally put them at risk. Parents and visitors should remain mindful of how easily infections can spread to a vulnerable infant.
By taking precautions, you can protect the baby’s health—and avoid the heartbreak of seeing a precious little one fall seriously ill.
