Cold sores are caused by the herpes simplex type 1 virus and are sometimes referred to as fever blisters. The virus is different than the type 2 virus found in the genitalia region. The blisters are small round raised bumps filled with fluid near the mouth. The blisters can appear alone or in small clusters. The condition can be transferred to a baby by someone who has the virus. Possible ways of transferring the disease include using the same utensil, kissing the baby or the baby putting an infected toy near his mouth.
Step 1
Visit the doctor. It is rare for an infant, especially 3 months or younger, to have the virus. The virus can spread to the eyes and brain, causing further complications.
Step 2
Place cold ice near the blister. The ice will reduce the swelling and discomfort of the blister.
Step 3
Give the baby a dose of acetaminophen or ibuprofen to reduce inflammation and pain.
Step 4
Place mittens or socks on the baby's hands. The baby will not be able to scratch the blisters and spread the virus. Wash the baby's hands on a regular basis through out the day.
Step 5
Place a hat on the baby when going out in direct sunlight. Sunlight can exacerbate the blisters and cause an increase in breakouts.
Tips and Warnings
- Most cold sores will disappear within five to 10 days and do not require treatment. Always follow a pediatrician's directions.
