The causative agent for shingles is the varicella-zoster virus (VZV), which is the same virus that causes chickenpox. After a person recovers from chickenpox, the virus remains dormant in the nerve tissues and can reactivate later in life, leading to shingles. This typically occurs when the immune system is weakened due to stress, aging, or other factors.
