Fever Blisters and the Herpes Simplex Virus

The herpes simplex virus type one or HSV-1 is usually the cause of fever blisters. Even more so than the herpes simplex virus type 2 or HSV-2. These infections follow the usual course of herpes simplex virus infections in that the first outbreak is usually more painful and lasts longer than recurrent infections.

Fever Blisters – Primary Infection

The first outbreak usually occurs in the mouth and this is usually the most painful.   This happens when the skin in and or around the mouth comes in contact with the herpes simplex virus.This occurrance is called gingivostomatitis and covers the mouth, gums, etc. This usually most often occurs between six months and three years of age. Children experience difficulty in swallowing, swollen lymph nodes, pain and fever. These symptoms last for about a week and resolve spontaneously. Children with gingivostomatitis are at risk for dehydration if the pain keeps them from drinking fluids. Water-based popsicles are sometimes used to provide hydration and pain relief.
