Another name for the fever blisters is cold sores. The main cause of this condition is herpes simplex virus, actually herpes zoster virus. There are two types of this virus, herpes zoster virus type 1 and herpes zoster virus type 2. In the majority of cases, oral herpes or cold sores are caused due to herpes simplex type 1, while genital herpes occurs due to herpes zoster virus type 2. However, it is not a rule.

On the other side, canker sores are not contagious and are marked by the occurrence of blisters inside the mouth.
