What is shingles?

Shingles (also known as herpes zoster) is a condition that
is caused by the reactivation of the chickenpox virus.

After people have chickenpox - usually as a child - the virus travels up a nerve
root and lies dormant (inactive inside you), near the spine. Later in life the virus
can reactivate and cause shingles. The reasons for reactivation aren't completely
known. Reaching an older age or having conditions that affect the immune
system make the virus much more likely to reactivate.

Shingles tends to occur more often in older people and is usually characterised
by a painful rash on one side of the body, which develops into fluid-filled blisters.
