Final answer:
Both Herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) can cause eye herpes, known as herpes keratitis, and digital herpes. HSV-1 is more commonly associated with eye infections and cold sores, while HSV-2 is generally linked with genital herpes. Treatment often involves the use of antiviral medications.
Step-by-step explanation:
Herpes simplex virus type 1 (HSV-1) is associated with infections in the eye, such as herpes keratitis, as well as oral lesions commonly referred to as cold sores or fever blisters. HSV-1 can be spread through direct contact and is highly contagious, with the possibility of the virus remaining latent for long periods. In contrast, herpes simplex virus type 2 (HSV-2) is generally linked with genital herpes. Both HSV-1 and HSV-2 are capable of infecting skin and mucous membranes anywhere on the body, although traditional associations are with oral and genital regions, respectively. When HSV-1 infects the eye, it can cause irritation, sensitivity to light, excess tears, and potentially severe keratoconjunctivitis which, if deep lesions form, may lead to blindness. Treatment for eye infections often involves antiviral medications. Herpes infections that affect the finger or hand, often termed 'digital herpes,' can also be caused by either HSV-1 or HSV-2, although HSV-1 is more commonly implicated. These infections may result from direct contact with the virus through an open area on the skin, such as a cut or abrasion.
