When a 9-month-old presents with fever and rash consistent with roseola, what is the most appropriate initial step regarding management?

• A. Order serology for HHV-6
• B. Reassure and observe
• C. Begin IV antibiotics
• D. Hospitalize

Answer: (B)

Roseola infantum is a self-limited viral illness in young children. The hallmark pattern is a period of high fever for several days followed by the appearance of a pink, blanching rash as the fever resolves. Because there’s no specific antiviral treatment for HHV-6 and the illness usually resolves on its own, the best initial step is reassurance and observation with supportive care at home. Focus on fever control and maintaining fluids, and avoid unnecessary tests or antibiotics. Serology for HHV-6 won’t change management and isn’t needed in typical cases. IV antibiotics aren’t indicated since this is a viral illness, and hospitalization isn’t required unless the child shows signs of dehydration, inability to keep fluids down, or a complication such as meningitis or another serious infection. If the child remains well-hydrated and clinically stable, outpatient management with return precautions is appropriate.
