What factors can cause herpes virus infection?

In daily life, some individuals develop herpes lesions, causing significant physical discomfort and severely affecting their quality of life and work performance. Understanding the condition is essential for effective prevention and treatment. So, what factors can trigger herpes virus infection?

What factors can trigger herpes virus infection?

Viral herpes primarily manifests in two forms. First, herpes simplex is caused by the herpes simplex virus (HSV). Primary infection may occur via direct or indirect contact—including genital herpes—mainly through unhygienic sexual contact or intercourse. After infection, the virus remains latent within local sensory nerve ganglia; when host immune function declines, the virus reactivates, leading to recurrent herpes outbreaks. Second, shingles (herpes zoster) results from reactivation of the varicella-zoster virus (VZV). The initial VZV infection typically presents as widespread vesicular rash—i.e., chickenpox. Subsequently, the virus also establishes latency in local sensory ganglia; upon immunosuppression, it reactivates, producing a unilateral, dermatomal cluster of vesicles characteristic of shingles.

Currently, it is believed that after herpes virus infection—including both shingles and genital herpes—the virus exhibits self-limiting behavior, with most cases resolving spontaneously within 1–2 weeks. The current therapeutic goal for shingles is to prevent secondary complications and recurrence; however, no definitive, highly specific antiviral drug has yet been established. Treatment principles focus on shortening disease duration, preventing secondary bacterial infection, and reducing recurrence risk.

Patients should avoid spicy, stimulating foods and “trigger foods” (foods traditionally believed to exacerbate certain conditions) in their daily diet. Maintaining adequate rest and high-quality sleep is also crucial. We hope this information proves helpful to you.
