Shingles vs. Stye: Different Causes, Different Locations

Shingles (Herpes Zoster)

• Cause: Reactivation of varicella‑zoster virus (VZV) from dorsal root ganglia.
• Presentation: Unilateral dermatomal vesicular rash, burning pain.
• Risk: Age >50, immunosuppression.

Stye (Hordeolum)

• Cause: Acute bacterial infection (usually Staphylococcus aureus) of eyelash follicle (external) or meibomian gland (internal).
• Presentation: Tender, red, swollen eyelid margin nodule; may point and drain.
• Common in children, but any age.

No Connection

Different pathogens (virus vs. bacteria), different anatomy (dermatome vs. eyelid gland), different triggers. Coincidental occurrence possible but not causal.
