Explanation / Answer

Answer: Option D is correct.

Explanation:

Varicella zoster is a herpes virus that causes chickenpox (varicella) in humans.

Chickenpox occurs when a person is infected for the first time whereas shingles are due to the reactivation of the latent virus in old age.

Varicella zoster remains in latent form in the nerves of dorsal root and trigeminal ganglia.

Reactivation of the virus occurs in people with the compromised immune system and old age.

Varicella zoster infection is prevented with a live attenuated vaccine. Shingles can also be prevented in older people with shingles vaccine.
