A group of nursing students are reviewing information about childhood infectious diseases. The students demonstrate understanding of this information when they identify which disease as a common childhood exanthem?

A. Rubella (German measles) is a viral infection characterized by a maculopapular rash, making it a classic example of a childhood exanthem. It typically presents with mild fever, lymphadenopathy, and rash, and is most common in children. B. Rabies is a viral disease transmitted through animal bites and does not cause a generalized rash, so it is not considered an exanthem. C. Mumps primarily affects the salivary glands, causing parotitis, and does not produce a generalized skin rash. D. West Nile virus can cause fever and neurological symptoms but is rarely associated with a rash, and it is not classified as a childhood exanthem.
