A nurse in a pediatric clinic is teaching a newly hired nurse about the varicella zoster virus. Which of the following information should the nurse include in the teaching?

A. Varicella (chickenpox) requires airborne and contact precautions, not droplet precautions, due to its high transmissibility. B. Aspirin should never be given to children with viral infections because it increases the risk of Reye’s syndrome, a life-threatening condition causing liver failure and encephalopathy. C. The herpes zoster vaccine (Zostavax or Shingrix) is for adults to prevent shingles, not for children with active varicella infection. D. Children with varicella are contagious from 1–2 days before the rash appears until all vesicles have crusted over (usually 5–7 days). They should be isolated from susceptible individuals during this period.
