Herpes Zoster or Varicella zoster virus (VZV) is the reactivation of the same viral infection that causes chickenpox which can stay dormant in nerves for many years. Shingles infection may arise when the individual’s immune system is weakened, commonly affecting older adults. Shingles presents as a painful unilateral rash often started by a tingling, burning sensation which leads to severe itching, aching, and blistering, where the blisters can be highly contagious. Shingles can cause severe complications if affecting the eyes and chronic nerve damage to the areas affected years after rash has cleared. As a virus that can stay dormant, it is possible for people to have multiple episodes of shingles with the risks increasing with age.
