Shingles and Chickenpox (Varicella-Zoster Virus) - Risk Factors

(Page 3)

These drugs are used for patients who have undergone organ transplantation and are also used for severe autoimmune diseases caused by the inflammatory process. Such disorders include rheumatoid arthritis, systemic lupus erythematosus, diabetes, multiple sclerosis, Crohn's disease, and ulcerative colitis.

Lack of Exposure to Children Infected with Chickenpox. Interestingly, one study suggested that previously infected adults who are exposed to children with chickenpox may receive an extra boost in antibody production, which can actually help them fight off herpes zoster. This means that as more children are vaccinated against chickenpox, more adults may be at risk for herpes zoster.

Risk Factors for Shingles in Children. Although most common in adults, shingles occasionally develops in children. One study reported that only 5% of cases occur in those under age 15. Children with immune deficiencies are at highest risk. Children with no immune problems but who had chickenpox before they were 1 year old also have a higher risk for shingles.
