Question: 1 / 505

What virus is responsible for shingles in the ophthalmic division of the trigeminal nerve?

Varicella Zoster Virus

The virus responsible for shingles, particularly in the ophthalmic division of the trigeminal nerve, is the Varicella Zoster Virus (VZV). This virus remains dormant in the body after an individual has had chickenpox, which is caused by the same virus. When it reactivates, it can lead to the development of shingles (herpes zoster), which may affect different nerves, including those in the trigeminal nerve, particularly its ophthalmic branch.

When VZV reactivates in this area, it can lead to painful rashes and potentially complications like postherpetic neuralgia or ocular problems, including keratitis. The association of VZV with shingles makes it the key virus to consider in this context, distinguishing it from other viruses listed in the choices, which are not known for causing shingles.
