What is a skin problem that is caused by a virus?

One common skin problem caused by a virus is herpes simplex, which can lead to painful sores or blisters around the mouth (cold sores) or genital area (genital herpes). This viral infection is highly contagious and can recur periodically, especially during times of stress or illness. The virus remains dormant in the body and can reactivate, causing flare-ups. Treatment typically involves antiviral medications to manage symptoms and reduce the frequency of outbreaks.
