Fig. 2.

Age and gender distribution of varicella zoster virus reactivation in the study population (a-f). The age distribution shows that predominantly patients above the age of 50 peaking in the eight decade of life were diseased. There was no gender difference. Patients with trigeminal root ganglionitis and dorsal root ganglionitis were predominantly diseased and showed skin lesions only (b, c). In five female patients, dorsal root ganglionitis with segmental skin lesions was accompanied by nerve affection due to radiculitis (marked in c). In the CNS infection group patients with encephalitis, meningitis, and myelitis were marked separately (e). The graph E shows that patients with encephalitis were older as compared to patients with meningitis. Graphs show numbers of female and male patients distributed in life decades
