Herpes Zoster: Risk Factors for Occurrence, Complications, and Recurrence with a Focus on Immunocompromised Patients

This is the authors' abstract. We don't add key points for this paper.

BACKGROUND: The varicella-zoster virus is a highly contagious human herpesvirus that primarily causes varicella (chickenpox) as an initial infection, targeting T cells, neurons, as well as skin cells, and can later reactivate to cause herpes zoster (shingles). Following reactivation, the varicella-zoster virus infection can lead to severe complications, the most common of which is postherpetic neuralgia. Risk factors include aging, immunosuppression, chronic diseases such as diabetes, cardiovascular disorders, respiratory conditions, and others. OBJECTIVE: In this article, we present an analysis of factors increasing the risk of herpes zoster occurrence, complications, and recurrences (in particular in immunocompromised patients).
