Background: Herpes zoster which is also known as shingles, caused by reactivation of latent Varicella-zoster virus from the dorsal root ganglion. Although it is usually self-limiting in healthy adults, immunocompromised individuals are at higher risk of developing severe or visceral or disseminated cutaneous involvement. The study aimed to analyse the clinical patterns and epidemiological factors of herpes zoster.

Methods: This was a cross-sectional study and conducted for 1 year. A total number of 100 patients with herpes zoster attending our dermatology outpatient department (OPD) were included in this study. A detailed epidemiological, clinical history and a complete dermatological examination were performed. Tzanck smear was done whenever necessary.

Results: Out of 100 patients with herpes zoster, 64% were males and 36% were females. The age group varied from 20-80 years. The most commonly affected age group was 41-50 years. Thoracic dermatome was most commonly affected by 48%, followed by lumbar dermatome. In the total study population, left side dermatomal affection (55%) was more than the right side. Most of the patients presented with pricking type of pain.

Conclusions: Herpes zoster can affect any age group with a higher incidence in elderly patients and immunocompromised individuals. Early recognition and treatment with antivirals within 72 hours of rash onset has shown a reduction in severity, complications, and postherpetic neuralgia.
