FlowerHerpes Simplex Virus and Cold Sores
What are cold sores?
Cold sores are small blisters around the mouth, caused by the herpes simplex virus. The most common strain of the virus is herpes simplex virus 1.

The herpes simplex virus is not curable, but may lay dormant for long periods of time. Episodes of the cold sores usually last no longer than two weeks. Hot sun, cold wind, a cold, or a depressed immune system can cause an outbreak 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. The following are the most common symptoms of cold sores. However, each child may experience symptoms differently. Symptoms may include:
  • tingling of the lips
  • a small blister or cluster of blisters on the lips and mouth that enlarge, burst, then crust over
  • itching and irritation of the lips and mouth
  • soreness of the lips and mouth that may last from three to seven days
The symptoms of cold sores may resemble other dermatologic conditions or medical problems. Always consult your children's physician for a diagnosis.
Treatment for cold sores:
Specific treatment for cold sores will be determined by your child's physician based on:
  • your child's age, overall health, and medical history
  • extent of the disease
  • your child's tolerance for specific medications, procedures, or therapies
  • expectations for the course of the disease
  • your opinion or preference
Although cold sores cannot be cured, treatment may help alleviate some symptoms, if severe. Treatment may include the following types of prescription medications:
  • idoxuridine paint
  • antiviral medication
