Also called: Herpes zoster, Postherpetic neuralgia
Shingles is a disease caused by the varicella-zoster virus – the same virus that causes chickenpox. After you have chickenpox, the virus stays in your body. It may not cause problems for many years. As you get older, the virus may reappear as shingles. Unlike chickenpox, you can’t catch shingles from someone who has it.
Early signs of shingles include burning or shooting pain and tingling or itching, usually on one side of the body or face. The pain can be mild to severe. Blisters then form and last from one to 14 days. If shingles appears on your face, it may affect your vision or hearing. The pain of shingles may last for weeks, months or even years after the blisters have healed.
There is no cure for shingles. Early treatment with medicines that fight the virus may help. These medicines may also help prevent lingering pain. A vaccine may prevent shingles or lessen its effects. The vaccine is for people 60 or over who have had chickenpox but who have not had shingles.
What Causes Shingles?
Shingles is caused by the same virus that causes chickenpox.
If you’ve had chickenpox (over 90% of US adults have), the virus remains in your body and can cause Shingles.
The chickenpox virus stays inactive in certain nerves.
If the virus becomes active again, usually later in life, it causes the painful disease called Shingles.
How Do You Get Shingles?
You are at risk for getting Shingles if you have had chickenpox. In addition:
Conditions that weaken the body’s immune (defense) system, such as aging, cancer, or certain drugs, increase the chance that the virus will become active again, resulting in Shingles.
You should know that there is no way to predict who will get Shingles, or when.
About half of the nearly 1 million Shingles cases in the United States each year occur in people aged 60 years and older.
1 out of 2 people living to age 85 will have Shingles.
The older you get, the longer the Shingles rash may last.
Key Facts About Shingles
