Together with herpes simplex virus (HSV), varicella zoster virus (VZV), also called human herpesvirus 3, is a member of the subfamily of Alphaherpesviridinae. Varicella zoster virus causes chickenpox, which becomes latent in the cranial nerve and dorsal root ganglia and can reactivate many years later to produce shingles. The commonest cause of viral recrudescence is decline in cell-mediated immunity.1
