A cold sore may seem like a small thing in adults, but around a baby, it can be much more serious.
Cold sores are caused by Herpes Simplex Virus Type 1. Many adults carry this virus, and for older kids and adults it often stays localized. But for babies, especially newborns, first exposure can lead to more severe infection.
For children with Eczema, HSV-1 can spread through broken skin and cause Eczema herpeticum, which needs prompt medical care.
If you have tingling, a blister, an open sore, or even a healing scab, the virus can still spread through saliva and skin contact.
Antiviral medications can help shorten symptoms, but they do not make it safe to kiss a baby during an active outbreak.
To reduce risk around a baby:
• avoid kissing the baby, especially face and hands
• wash hands before touching baby or baby items
• avoid sharing utensils, cups, towels, or lip products
• keep the sore covered and avoid touching it
• consider wearing a mask if close contact is needed
• be extra cautious with newborns and babies with eczema
Babies put their hands in their mouths often, so even contact with hands or objects matters.
Cold sores are common and nothing to feel ashamed about. But understanding how to reduce spread is especially important around babies.
Have you ever had to set a “no kissing” boundary?
