What is Shingles?
- Shingles is a painful skin rash that is caused by the varicella zoster virus. This is the same virus that causes chicken pox. In people who have had chicken pox, the virus lays dormant in nerve cells in the body. In some people, for reasons that are not clear, the virus may become active again, resulting in Shingles.
- Shingles causes a painful, blistered rash on the skin.
- Shingles occurs more frequently in adults over 50 years of age and in those with a weakened immune system.
- 1 out of 5 people who have had shingles may continue to have severe pain that can last months to years after the rash has disappeared. This is known as post-herpetic neuralgia.
- In rare cases shingles can cause pneumonia, hearing or vision loss, scarring, inflammation of the brain (encephalitis) or death.
- You cannot catch shingles from a person who has shingles It is possible for someone who has never had chicken pox or the chicken pox vaccine to get the virus from someone with shingles, though it is rare.
