There are two types of herpes simplex viruses (HSV). HSV type 2 is the one that most commonly causes genital herpes. You can get HSV type 2 during sexual contact with someone who has a genital HSV-2 infection. The infection causes painful sores on the genitals in both men and women. HSV type 1 is the herpes virus that is usually responsible for cold sores of the mouth, the so-called "fever blisters." You get HSV-1 by coming into contact with the saliva of an infected person.
However, HSV type 1 can cause genital herpes, usually caused by oral-genital sexual contact with a person who has the oral HSV-1 infection, and HSV type 2 can cause cold sores.
Herpes can be treated but not cured. Symptoms appear briefly and then disappear; the disease lies dormant in nerve cells, but it may be reactivated by stress or illness. It is believed to be more contagious during active periods when blisters are present, however, it can be transmitted person-to-person without active lesions.
If I were you, I would keep those fingers covered with band-aids so you don't infect anyone else or any other body parts belonging to you or anyone else.
