A patient presents with a vesicular rash in a dermatomal distribution that does not cross the midline. The causative agent is a double-stranded DNA virus that remains latent in dorsal root ganglia after primary infection. Which virus is responsible for this condition?

✓ Correct Answer: Option B

Varicella-Zoster Virus (VZV) causes chickenpox (primary infection) and subsequently establishes latency in dorsal root ganglia. Reactivation leads to herpes zoster (shingles), characterized by a painful vesicular rash in a dermatomal distribution.
