Cold Sores - Ask Dr Sears

The Common Cold Sore

Cold sores are a common and harmless virus that most people will experience at some time in their lives.

Signs That You’ve Been Infected

Tingling or soreness of the lips (occurs shortly before the breakout of sores)

Appearance of blister-like sores that break and ooze for 7 to 10 days

Sometimes accompanied by swollen neck glands, swollen lips, and a low-grade fever

How It’s Transmitted

Physical contact with the sores

Germs spread through sneezing and coughing

Mouthing or sharing toys

Sharing cups or eating utensils

Treatment of Cold Sores

Antiviral medications either applied in ointment form or taken orally can shorten the length and severity of the breakout, especially if used in its early stages (when your lips start to tingle or feel sore).

Sun-protective ointments and lip balms

For soreness and itching, enjoy a well-placed popsicle on your lips.

Additional Precautions To Take

Cut your child’s fingernails as short as you can to discourage picking at the sores.

Wash your child’s hands regularly so he doesn’t infect other parts of his body or share the germ with his friends.

The American Academy of Pediatrics’ Committee on Infectious Diseases does not recommend exclusion of children with cold sores from daycare or school, but advises covering the sores with clothing or a bandage.
