The kiss-des-death: why are cold sores dangerous for babies?

Fever blisters caused by herpes simplex virus are not only annoying for adults, but can also be dangerous for babies. A newborn baby's immune system is not yet fully developed, making them particularly vulnerable to infections. This can cause a infection with herpes simpleplex virus serious complications, potentially lifelong consequences.


Risks for babies

In young babies, herpes simplex virus infection can be very serious due to their immature immune system. Infants between 4 and 6 months of age are particularly at risk of serious complications such as spreading the virus to the brain and other organs, which can lead to serious conditions such as cerebral or meningitis, with permanent injuries and even death.


Preventive measures

The risk of infection is highest when fever blisters are active, but also before the vesicles appear, the virus can be transmitted. Fever blisters remain contagious until they are completely dehydrated, which usually takes one to two weeks. To prevent infection of a baby:

  • Avoid contact between the baby and persons with active cold sores, including hugging and kissing.
  • Wash your hands thoroughly before you take care of the baby or nourishe it, and every time after touching your lips.
  • Clean things that come into contact with the baby's mouth, such as bottles and pacifiers.
  • Use separate towels and washcloths for the baby, and avoid contact with cold sores.

What to do in case of infection

If a baby under 6 months of age shows signs of a cold sore or other symptoms of infection (such as fever, listlessness or drinking poorly), consult a doctor immediately. The virus can cause severe damage quickly, so early treatment is crucial. A doctor will probably prescribe antiviral medication immediately. If the virus enters the baby's eyes, this may lead to eye infections with permanent damage.

It is vital to protect the health of babies from the dangers of cold sores, and by being aware of the risks and taking preventive measures, parents and caregivers can minimise the risk of infection and protect the safety of their little ones.
