Oral Herpes: Herpes Simplex 1 Virus (HSV1)

Herpes cold soresMost people with oral herpes might not even be aware that they carry the virus. They don’t always show any symptoms. Blisters, otherwise known as cold sores, are generally caused by the herpes simplex 1 virus. They are easily passed from kissing. If your aunt kisses you, and she has a blister, chances are that you are now a carrier of the herpes simplex 1 virus.

The blisters can be painful, and are very contagious.

If you have a breakout of oral herpes, the recurrence factor is about 60%.
