Which condition is caused by the varicella-zoster virus and presents as shingles?

The condition caused by the varicella-zoster virus that presents as shingles is herpes zoster. This viral infection arises from the reactivation of the varicella-zoster virus, which is the same virus responsible for chickenpox. After an individual recovers from chickenpox, the virus remains dormant in the sensory nerve ganglia and can reactivate later in life, particularly during times of stress or weakened immunity, leading to shingles.

Herpes zoster typically manifests as a painful rash that forms blisters along a dermatome, which is an area of skin supplied by a single spinal nerve. The presentation often includes symptoms like burning or tingling sensations prior to the appearance of the rash, and the skin lesions can be quite painful.

Understanding this connection between varicella-zoster virus and herpes zoster is crucial, as it helps in identifying the nature of shingles and the clinical implications associated with it.
