QuestionChoice
No, this is not the correct answer. The ventral root provided motor supply via the spinal nerves. The varicella-zoster virus remains dormant in the dorsal root ganglion.

Ventral root
QuestionChoice
Yes, this is the correct answer. The varicella-zoster virus remains dormant within the dorsal root ganglion of the central nervous system and once activated the virus can travel more distally through the spinal nerve and infect the skin in the distribution of the specific spinal nerve. This often presents as dermatomal lesions. Note that a dermatome refers to an area of skin supplied/innervated by a single spinal nerve.

QuestionChoice
No this is not the correct answer. The varicella-zoster virus remains dormant in the dorsal root ganglion.

Cerebellum
QuestionChoice
No this is not the correct answer. The sympathetic ganglion is where pre-ganglionic sympathetic neurons synapse with post-ganglionic sympathetic neurons to supply the autonomic functions of tissues. The varicella-zoster virus remains dormant in the dorsal root ganglion.

d
Sympathetic ganglion
QuestionChoice
No this is not the answer. Varicella-zoster can remain dormant in this structure, however, this only occurs in trigeminal herpes zoster. In trigeminal herpes zoster, there are vesicles located in the skin of the face. By contrast, this patient has skin lesions on his back, making this option less likely.

A 67-year-old man presents to the GP with symptoms of headache, fever and pruritic skin changes on his back. On examination, the GP notes the presence of small vesicles distributed in a specific anatomical pattern around the skin. A diagnosis of shingles is made, where the causative pathogen is varicella-zoster-virus.

In which part of the central nervous system is the varicella-zoster virus most likely to remain dormant?
