Same Herpes Zoster case — the affection is on which side relative to the nerve?

Correct answer: D. Ipsilateral (same side)

• A. Herpes zoster is specifically and characteristically IPSILATERAL and dermatomal — it has a very specific laterality.
• B. Contralateral manifestations would indicate a CENTRAL nervous system lesion (like stroke), not a peripheral nerve/ganglion infection like herpes zoster.
• C. Bilateral herpes zoster is extremely rare and only occurs in severely immunocompromised patients — the typical pattern is UNILATERAL, IPSILATERAL.
• D. Herpes Zoster follows a DERMATOMAL pattern — the rash, vesicles, and associated symptoms occur IPSILATERALLY (on the SAME SIDE) as the nerve ganglia where VZV has reactivated. It characteristically does NOT cross the midline. Therefore, all symptoms (oral vesicles, taste change, pain) are on the SAME SIDE as the affected nerve.
