B. A well-appearing, previously healthy 68-year-old man with a temperature of 39.4°C (103°F), cough, myalgia, clear lungs, and no respiratory distress on examination
C. A well-appearing, previously healthy 12-year-old boy with a temperature of 39.4°C (103°F), cough, sore throat, clear lungs, and no respiratory distress on examination

Answer: C. During periods of low local prevalence of influenza, patients with influenza-like illness who have mild-to-moderate symptoms and no high-risk factors for a more severe disease course do not require testing for influenza and can be treated with supportive therapy alone. A previously healthy 12-year-old boy with without any signs of respiratory distress or compromise is a candidate for supportive therapy. A history of asthma, patient age <2 years, and patient age ≥65 years are each risk factors for a more severe disease course in influenza; when there is low local prevalence of influenza, rapid testing should be administered to patients in these groups who present with influenza-like illness so that antiviral therapy can be initiated if indicated.
