What is viral herpes zoster?

Viral herpes zoster is seen in dermatology. Herpes zoster and chickenpox are caused by the same varicella zoster virus infection. Chickenpox can theoretically occur through direct contact with herpes zoster blister fluid. However, chickenpox is mainly transmitted through respiratory droplets, so patients with herpes zoster are not the main source of infection for chickenpox. Patients with chickenpox or herpes zoster cannot directly infect others with herpes zoster because herpes zoster results from latent varicella zoster virus infection. Herpes zoster occurs in spring and autumn, and is common in adults. Skin lesions generally occur on one side of the body and are distributed in a zoster. The rash is a cluster of miliary to mung-bean-sized hillocks and blisters, which can be accompanied by different degrees of neuralgia.
