Fever blisters may not be a sign of illness, but are a common mouth disorder that is caused by a virus known as herpes simplex. The condition is highly contagious and is commonly transmitted from one person to another through kissing, states the National Institute of Dental and Craniofacial Research. Children may get fever blisters when they come into close contact with friends, family members and other people.
Fever blisters are common in the United States and they tend to be recurrent. The recurrence of fever blisters is usually triggered by different factors, including stress, exposure to sunlight, injury, illness and fever, notes the National Institute of Dental and Craniofacial Research. The condition tends to be more recurrent in women during their menstrual periods. Research is still ongoing to learn the main causes of recurring fever blisters.
As of March 2015, there is no known cure for fever blisters. There is also no vaccination for preventing blisters. However, there are ointments and antibiotics that can be used to help ease discomfort and pain. The best way to manage fever blisters is to keep them clean to avoid getting bacterial infections. Avoiding kissing and touching the mouth is necessary to prevent transmission to other people. Children should wash their hands regularly to prevent spreading this condition.
