Which condition is caused by a virus traveling over the neural pathway?

One condition caused by a virus traveling over the neural pathway is herpes zoster, also known as shingles. It occurs when the varicella-zoster virus, which causes chickenpox, reactivates in the nerve cells after lying dormant. This reactivation leads to painful rashes and can affect specific areas of the skin corresponding to the affected nerve pathways. Shingles can also result in complications such as postherpetic neuralgia, characterized by prolonged pain after the rash resolves.
