A school-age child with fever, sore throat, exudative tonsils, a diffuse erythematous sandpaper-like rash on the neck and trunk, and a positive rapid strep test is treated with which of the following?

• A. Hospitalize for observation
• B. Prescribe intravenous antibiotics
• C. Oral amoxicillin
• D. Refer to a pediatric infectious disease specialist

Answer: (C)

In this scenario, the child has signs highly suggestive of group A streptococcal pharyngitis with scarlet fever (fever, sore throat, exudative tonsils, and a diffuse erythematous sandpaper-like rash) and a positive rapid strep test. The goal of treatment is to eradicate the bacteria, prevent non-suppurative complications like rheumatic fever, and reduce contagiousness. Oral amoxicillin is the best choice because it is highly effective against group A Streptococcus, well tolerated in children, and easy to administer due to its pleasant taste and convenient dosing schedule. A typical course is about 10 days, which effectively clears the infection and helps resolve symptoms and the rash as the toxin-mediated effects subside. Hospitalization or intravenous antibiotics are not needed for an otherwise healthy child who can take oral medications, unless there are signs of dehydration, inability to swallow, airway concern, or other severe illness. Referral to a pediatric infectious disease specialist is unnecessary for uncomplicated GAS pharyngitis with scarlet fever. If penicillin allergy is present, alternatives can be considered (such as a cephalosporin if the allergy is not severe, or a macrolide like azithromycin), but penicillin-class therapy remains the standard first choice in typical cases.
