Risk Factors
Only people who were previously infected with VZV (through natural infection that caused varicella or varicella vaccination) can develop shingles. Although many people do not remember, approximately 99.5% of people born in the United States who are 40 years of age and older have had varicella. As a result, all older adults in the United States are at risk for herpes zoster.
The reasons why VZV reactivates and causes herpes zoster are not well understood. However, a person's risk for herpes zoster may increase as their VZV-specific cell-mediated immunity declines. This decline in immunity can result from increasing age and/or immunosuppressive medical conditions and medications.
A person's risk for herpes zoster increases sharply after 50 years of age. About 50% of people who live to 85 years of age will have had an episode of herpes zoster. A person’s risk for PHN also increases sharply with age. The oldest adults with herpes zoster are most likely to be hospitalized for complications from the disease and to develop PHN.
People with compromised or suppressed immune systems who have an increased risk for herpes zoster include those:
- with cancer, especially leukemia and lymphoma,
- with human immunodeficiency virus,
- who have undergone bone marrow or solid organ (renal, cardiac, liver, and lung) transplantation, or
- who are taking immunosuppressive medications, including steroids, chemotherapy, or transplant-related immunosuppressive medications.
Other potential risk factors for herpes zoster have been identified but the findings are not consistent in all studies. For example-
- Some studies found that more women than men develop herpes zoster, but other studies did not find a difference [1][2]; the reason for a possible difference between women and men is not known.
- Some studies conducted in the United States and elsewhere found that herpes zoster is less common in African Americans (by at least 50%) than in whites[3].
