Final answer:
The varicella-zoster virus hides dormant in the dorsal root ganglia and its reactivation likely causes shingles.
Step-by-step explanation:
The subject of this question is the varicella-zoster virus and its reactivation causing shingles. The varicella-zoster virus can become dormant in the dorsal root ganglia and remain latent for years.
