Ramsay Hunt Syndrome (RHS) is a rare neurological disorder caused by a type of virus. This complex disease results in facial nerve paralysis (facial palsy) and affects the ear or mouth.
Cause of Infection:
Ramsay Hunt Syndrome is caused by the varicella zoster virus (VZV). This same virus causes chickenpox in children and shingles (herpes zoster) in adults. In the case of Ramsay Hunt Syndrome, if the dormant/inactive VZV virus is present in the body previously, it becomes active again and spreads to affect the facial nerve, resulting in the paralysis of the affected area.
