Herpes zoster/shingles resources for patients/public
Herpes zoster, more commonly known as shingles, is caused by reactivation of the varicella zoster virus (VZV), which remains in the body indefinitely, usually following the illness of chickenpox. The virus reactivates when a person's immune system is damaged, either by illnesses such as AIDS or treatments such as steroids or chemotherapy for cancer. Shingles causes an intensely painful rash, usually affecting one or more dermatomes (the area of skin supplied by a particular spinal nerve root). Antiviral treatments significantly reduce the pain, duration and complications of shingles.
