The distribution of the neurotropic alphaherpesviruses-herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) and varicella zoster virus (VZV)-was determined in autonomic and sensory ganglia of the head and neck obtained from formalin-fixed human cadavers. HSV-1 and VZV DNA were found in 18 of 58 and 16 of 58 trigeminal, 23 of 58 and 11 of 58(More)
