General Virology and DNA Viruses
A 3-year-old girl presented to her pediatrician's office with fever, swollen lymph nodes, and a vesicular rash on her chest and upper arms. The vesicles were at various stages of development: some were newly forming, while some were crusted over. Which of the following infectious agents is the most likely cause of this girl's rash? (AIPG 2010)
VZV produces a vesicular rash commonly seen in children, and different "crops" of vesicles generally appear on the head and trunk then moving outward; answers A, B, C are incorrect, smallpox infection produces a vesicular rash with all lesions being at the same stage of development, whereas parvovirus B19, EBV, and the measles virus does produce a rash, but not consisting of vesicular lesions.
