Shingles belongs to a group of diseases of a viral nature, caused by reactivation of the chickenpox virus or hemiplegia. The clinical manifestations occur on the skin surface, in the area of the affected ganglion, in the form of blisters and a rash. There is a lack of information in the literature on recurrent herpes zoster, which is the reason why a group of Japanese researchers undertook an observational study to identify and define the clinical and immunological features of recurrent herpes zoster.
