Herpes Zoster (Shingles)

• Herpes zoster (Shingles) is a painful skin rash
  which is caused by the varicella-zoster virus
  (VZV). This is the same virus that causes
  chickenpox. After a person has chickenpox, the
  virus remains inactive in the nerve cells.Years
  later, the virus can become active again. If it
  happens, a red rash or small blisters occur,
  generally on one side of the body, spreading
  along a nerve pathway where the virus was
  inactive.Sometimes, even after the rash is
  gone, the pain may continue for a prolonged time.
  This is a complication called postherpetic
  neuralgia (PHN).

• People who get the chickenpox vaccine still have
  a small risk of Herpes zoster (Shingles),
  although it appears to be less than the risk
  after an actual chickenpox infection.People
  with a weak immune system are at greater risk of
  getting shingles. Almost half of the cases of
  shingles occur in people older than age 60.The
  incidence of Herpes zoster (Shingles) occurring
  in children is low, but the risk of getting this
  disease increases with age. Children who have
  weak immune systems may have the same, or more
  severe, symptoms as adults.

• PHN can cause pain for weeks, months, and rarely
  even years after the rash resolves

What is the treatment for Herpes zoster
(Shingles)?

• Immediate treatment with antiviral medicines may
  help lessen the duration and severity of some of
  the symptoms. These antiviral medicines
  (acyclovir, famciclovir and valacyclovir) are
  more effective the sooner they are started.Ask
  your doctor about over-the-counter pain
  relievers. If your pain is severe, your provider
  may prescribe stronger pain medicine. You and
  your doctor will decide on the best treatment
  based on factors including duration and severity
  of the symptoms.
