Herpes Simplex Virus or Cold Sores

What are cold sores?


Once infected, the herpes simplex virus becomes dormant (inactive) for long periods of time and may reactivate, during which time cold sores reappear. Episodes of the cold sores usually do not last longer than 2 weeks. Hot sun, cold wind, a cold, or a depressed immune system can cause a reactivation of herpes simplex virus symptoms.


What are the symptoms of cold sores?

Some children and adults never experience any symptoms with the first attack; others have severe flu-like symptoms and ulcers in and around the mouth. Recurrences of cold sores are usually not as severe as the original outbreak. These are the most common symptoms of cold sores:


  • Tingling, itching, and irritation of the lips and mouth


The symptoms of cold sores may look like other skin conditions or medical problems. Always see your child's healthcare provider for a diagnosis.

What is the treatment for cold sores?

Although the herpes simplex virus infection that causes cold sores cannot be cured, treatment may help relieve some cold sore symptoms, if severe. Treatment may include antiviral medicine and other types of prescription medicines. These medicines work best if started as soon as possible after the first sign of a herpes infection or recurrence. Always see your child's healthcare provider.
