What is Shingles?

Shingles is caused by a virus called varicella zoster, the same virus that causes chickenpox. When you recover from chickenpox most of this virus is destroyed, but some survives and lies inactive in your body’s nervous system.

The virus can then become active again later in life, when your immune system has been weakened by age, stress, illness or certain treatments that can reduce your immunity.
