Final answer:
Herpes zoster is also known as B.shingles, which is caused by the varicella-zoster virus that also causes chickenpox. Shingles produces painful, localized rashes and can be reactivated decades after the initial chickenpox infection.
Step-by-step explanation:
Herpes zoster is also called B. shingles.
It is caused by the reactivation of the varicella-zoster virus, which is the same virus that causes chickenpox.
Shingles typically manifests as a painful, localized rash on one side of the body and may result in a condition called postherpetic neuralgia.
Unlike chickenpox, which is a common childhood disease with pustular lesions spread over the trunk, shingles is more focused on one area and is the result of the dormant virus being reactivated later in life.
Possible triggers for this reactivation include stress, aging, and immunosuppression.
