What is shingles?

You might think of shingles as “just a rash.” While that may be true for many younger people, the viral infection can have serious consequences for older adults. And given that the risk of developing shingles increases with age, it’s something you want to help your aging loved one guard against.

Shingles is caused by the same virus that causes chickenpox. The virus goes dormant in the body after infection. Decades later, as the immune system weakens, it can reactivate and cause a rash of very painful blisters. The most common complication is postherpetic neuralgia, nerve pain that can linger for months or even years, affecting mobility and daily life. Shingles also increases the risk of stroke or heart disease. When it affects the face, it can lead to vision loss.

Symptoms. Watch for tingling, itching, and a stripe of rash on your relative, usually on one side of the torso or face. They may also experience fever, headaches, and chills. If you notice these symptoms, seek out a diagnosis immediately. The sooner they begin treatment with an antiviral medication—usually multiple daily doses of a pill—the better.

Shingles is not contagious. But if someone who’s never had chickenpox touches the blisters, they could catch the chickenpox virus.

Preventing shingles. If your loved one is age fifty or older and hasn’t had the shingles vaccine, now’s a good time to talk about it. Called “Shingrix,” the two-part vaccine is over 90% effective at preventing shingles. Interestingly, a 2025 study found that people who were vaccinated were also 20% less likely to develop dementia over seven years. That’s good news!

Most pharmacies and doctor’s offices offer the vaccine. It’s usually covered by Medicare Part D and many private plans. Even if your relative has already had shingles—or received the older Zostavax vaccine—ask their healthcare provider about getting Shingrix.
