- Being older than 50. Shingles is most common in people older than 50. The risk increases with age. Some experts estimate that half the people 80 and older will have shingles.
- Having certain diseases. Diseases that weaken your immune system, such as HIV/AIDS and cancer, can increase your risk of shingles.
- Undergoing cancer treatments. Radiation or chemotherapy can lower your resistance to diseases and may trigger shingles.
- Taking certain medications. Drugs designed to prevent rejection of transplanted organs can increase your risk of shingles — as can prolonged use of steroids, such as prednisone.
