Herpes zoster is the medical name for shingles. It is caused by reactivation in the adult years of the chicken pox virus that occurred during childhood (the varicalla-zoster virus). The virus can be reactivated when the body's immunity to the virus breaks down. This may happen due to normal aging, or the body's immune system may become weakened due to stress from illness, physical or emotional stress, fatigue, poor nutrition, certain medications, chemotherapy, radiation therapy, or other factors.
