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.
Fever blisters are highly contagious and can be easily spread from person to person. Therefore, it is very important to avoid kissing during this condition. On the other side, canker sores are not contagious and are marked by the occurrence of blisters inside the mouth. Unlike fever blisters that are caused by a virus, the canker sores are caused bybacteria.

When fever blisters emerge, they are usually accompanied by fever, swollen lymph nodes in the neck, weakness and body ache.
