Q. A 29-year-old male teacher presents to the primary care clinic complaining of gradually worsening symptoms over the past 3 days. He recalls that his initial symptoms started with a scratchy throat and sneezing while supervising outdoor play for his students. Over the next day, he developed a fever, with temperatures spiking up to 100.5°F in the evenings, and a persistent sore throat accompanied by increased nasal congestion, a constant clear nasal discharge, tearing of the eyes, and a mild frontal headache. He also mentions experiencing body aches, making it hard to get through the school day. He denies recent travel, contact with sick people, or other high-risk exposures. He mentions several students in his class have similar symptoms. On physical examination, the physician noted an erythematous throat without exudates, clear rhinorrhea, and no cervical lymphadenopathy. His chest is clear on auscultation, and there are no rashes on his body. What is the most appropriate management for this patient's presentation?
