Herpetic whitlowhttps://en.wikipedia.org/wiki/Herpetic_whitlow
Herpetic whitlow is a lesion on a finger or thumb caused by the herpes simplex virus. It is a painful infection that typically affects the fingers or thumbs.

Herpetic whitlow can be caused by infection by HSV-1 or HSV-2. HSV-1 whitlow is often contracted by health care workers that come in contact with the virus; it is most commonly contracted by dental workers and medical workers exposed to oral secretions. It is also often observed in thumb-sucking children with HSV-1 oral infection, and in adults aged 20 to 30 following contact with HSV-2-infected genitals.

Herpes simplex virus (HSV) is common and is most often transmitted in childhood through direct physical contact. The most common infectious sites are oral mucosa (HSV-1) or genital mucosa (HSV-2). Rarely, the infection may be spread to the distal phalanx via direct inoculation and cause pain, swelling, erythema, and vesicles in an entity known as herpetic whitlow.
