A 9-month-old girl is brought to the clinic with a blanching, pink, maculopapular rash on her trunk, which appeared shortly after her fever resolved. The mother reports that the child had a 4-day history of high fever, but the child remained playful and alert throughout. There are no signs of cough, conjunctivitis, or lymphadenopathy. Question: What is the most appropriate management for this patient?
