This Painful Disease Once Seen as an Older Person's Problem Is Rising Among Millennial Women

Shingles cases appear to be climbing among younger and middle-aged adults, with millennial women emerging as a group that may face a particularly elevated risk of the painful viral infection.The trend is challenging the long-held perception that shingles is primarily an illness of older adults. Recent research has found that shingles cases among people ages 30 to 49 more than doubled between 1998 and 2017 in the United States, while newer research suggests that certain health conditions may put adults in their 30s at risk comparable to that of some older people.The Royal College of General Practitioners Research and Surveillance Centre has also reported that shingles activity in the United Kingdom is currently above the five-year average. Increased diagnoses through the Pharmacy First program, which allows community pharmacists to assess and treat certain conditions, may partly explain the rise in recorded cases.Younger adults are facing a risk many don't expectShingles, also known as herpes zoster, occurs when the varicella-zoster virus, the same virus that causes chickenpox. reactivates after remaining dormant in the nervous system.The infection typically causes pain, tingling, or unusual sensitivity in one area of the body, followed by a blistering rash. But younger adults may not immediately recognize the symptoms as shingles, potentially delaying treatment.That can matter because antiviral medicines are generally most effective when started early. In some cases, shingles can also cause postherpetic neuralgia, a form of persistent nerve pain that continues after the rash has cleared.A 2026 study found that adults ages 30 to 39 with certain conditions, including asthma, diabetes, depression and stress, had a higher risk of shingles than immunocompetent adults ages 50 to 59.The findings suggest that chronological age alone may not tell the full story when it comes to shingles risk.Why millennial women may be especially vulnerableWomen appear to be disproportionately affected. Across most age groups, women have been estimated to have about a 56% higher likelihood of developing shingles than men, although researchers have not established a single explanation for the difference.Experts have pointed to differences in immune function as one possible factor. Women are also more likely to develop certain autoimmune conditions, which can affect immune responses.For younger adults, other pressures may also come into play. Researchers have examined the potential role of chronic stress, depression, poor sleep, and other factors that can affect overall health and immune function.Jennifer Moffat, an associate professor of microbiology and immunology at the State University of New York Upstate Medical University, has suggested that broader changes in health and lifestyle could be contributing to the increase in shingles cases among younger people.The theory remains under investigation; however, no single explanation has been proven to account for the long-term rise in shingles cases.The pain can last long after the rash disappearsWhile shingles is usually not life-threatening, its complications can be serious. The infection can affect the face and, when it involves the eye, potentially threaten vision.One of the most concerning complications is postherpetic neuralgia, which causes persistent nerve pain after the rash has resolved. The condition is more common with increasing age but can occur in younger patients as well.The infection can also be overlooked when symptoms appear before the characteristic rash or when the rash develops in an unusual location. That can lead to delays in recognizing the condition and starting treatment.Vaccination remains focused on older and high-risk groupsShingles vaccination policies vary by country. In the UK, routine vaccination is primarily offered to older adults, while in the US, vaccination is generally recommended for adults ages 50 and older, as well as certain younger people with weakened immune systems.The growing evidence of shingles among younger adults, however, has renewed questions about whether more people should be aware of their individual risk factors.For now, experts emphasize that younger age does not make someone immune to shingles. Adults experiencing unexplained localized pain, tingling, or a blistering rash may need prompt medical evaluation, particularly if symptoms appear around the eyes or face.
