Shingles (herpes zoster) is caused by the varicella zoster virus, the same virus which causes chicken pox. Unlike other infectious diseases you don’t catch it from someone else. Most people had chickenpox when they were young. The virus that caused it can stay in your body for the rest of your life without you knowing it is there. The virus can then become active again later in life. It's not known exactly why the shingles virus is reactivated at a later stage in life, but most cases are thought to be caused by having lowered immunity (protection against infections and diseases) which may be due to age, illness, stress or medication.
Shingles is caused by the reactivation of an infection of a nerve and the area of skin that it serves, resulting in clusters of painful, itchy, fluid-filled blisters. The fluid from these blisters can spread chickenpox to those who have not had it.
If you have shingles try to avoid:
Shingles is most common in adults over 70 years. It's estimated that around one in every four people will have at least one episode of shingles during their life and around 1in every 1,000 cases in adults over 70 is fatal.

People become eligible for the free shingles vaccine when they turn 70 years of age, and remain eligible for the vaccine until their 80th birthday.
The shingles vaccine helps to protect you by boosting your immunity and reducing your risk of getting shingles. If you do go on to have shingles, your symptoms may be milder and the illness shorter.
If you have any questions or require further information about the Shingles vaccine speak to your GP or Practice Nurse
There are two shingles vaccines in use in Wales.
Zostavax is most commonly used in Wales. It is a live vaccine. You require one dose which is normally given as a single injection into the muscle of the upper arm.
Shingrix is used for those who have weakened immune systems (severely immunosuppressed). It is not a live vaccine. If given Shingrix you will require two doses, two months apart. It is normally given as an injection into the muscle of the upper arm.
If you would like to learn more about these vaccines, access the patient leaflets:
