چکیده
Definition Varicella-zoster virus (VZV), also known as Human Herpes Virus III (HHVIII), is a member of the herpes virus group. As all the other viruses from this group, VZV can manifests itself as a recurrent infection. After entering the body and causing primary infection, varicella-zoster virus remains latent in the neurons of sensory ganglion, especially dorsal roots of ganglion of the spinal nerves and extramedullar ganglion of the cranial nerves. Reactivation of the VZV infection is easily triggered by immune suppression. VZV infection is common in elder persons, immunocompromised or HIV positive individuals, and patients affected by malignant blood dyscrasias, malignant tumours, or undergoing immunosupressive therapy and radiotherapy.
