Varicella, or chickenpox, is a highly infectious disease caused by Varicella-zoster virus (VZV). Chickenpox can cause rash, blister formation and itchiness for around 5 days. Chickenpox is more common among younger people and VZV remains in the body after chickenpox heals. The virus that remained in the body can be reactivated at a later age, turning to shingles. Shingles may appear in any parts of the body, however, it most often appears as a single strip of rash with pain that wraps around one side of the torso.
