This might be from immunosenescence \u2013 the gradual decline in immunity associated with increasing age.<\/p>\n<h3>2.\u00a0\u00a0\u00a0\u00a0 Immunosuppression<\/h3>\n<p>Diseases that compromise the immune system, like cancer, AIDS, diabetes, leukemia, chronic kidney disease, inflammatory bowel disease (IBD), multiple sclerosis, \u00a0and lymphoma increase the risk of shingles, as do immunosuppressive medications for things like rheumatoid arthritis and bone marrow and organ transplants. Drugs like corticosteroids, chemotherapy, and transplant-related immunosuppressive medications are also associated with shingles.<\/p>\n<h3>3.\u00a0\u00a0\u00a0\u00a0 Being female<\/h3>\n<p>In a recent prospective study, researchers found that herpes zoster was significantly associated with being female. <a href=\"#_edn3\" name=\"_ednref3\">[iii]<\/a> They examined the data on more than 27 million individuals and out of almost a million diagnosed shingles cases, 62% were women.<\/p>\n<p>Autoimmune diseases also affect more women than men.
