What are fever blisters caused from?

A fever does not cause fever blisters, just like a cold doesn't cause cold sores (they are the same thing) but if infected with the Herpes Simplex I virus, a person's immune system is compromised and the virus can come out of its dormant stage. Too much sun, stress, certain foods, suppressed immune system are a few of the predisposing factors that can bring the Herpes Simplex Virus I out of its dormant stage. Remember once you have the virus, you will always have it. There is no cure.
