Shingles. If you had chicken pox as a child, the virus is already in your body. It remains dormant in most people but can activate if the immunity is lower e.G in hiv, cancer or even old age. These days it can be effectively treated if medical attention is sought early on. If you think you have shingles, please see a physician as soon as you can.
Chickenpox Part II. Shingles (varicella zoster) is a reactivation of the chicken pox infection you had as a child. The virus remains dormant in the body.

Children are now receive chicken pox vaccine which should prevent future shingles.
