A 20-year-old college student presents for evaluation of cough and fever. He states that he started feeling ill several days ago. His symptoms include fever (100.5°F), headache, and body aches. He has missed 2 days of classes and is feeling worse. He has tried a few over-the-counter cough and cold medications without relief. Several other students have been ill on campus. On examination, there is a frequent cough but overall, he does not appear in any distress or discomfort. Vital signs show a temperature of 100.5°F, pulse 90 beats/min, and respiratory rate 22 breaths/min. His pharynx is injected; otherwise, a head and neck examination is normal. His lung examination is notable only for some scattered rhonchi. The remainder of his examination is normal. Chest radiography shows some patchy infiltration. A sputum Gram stain shows white blood cells but no organisms. What antibiotic class is considered first line for treatment of his condition?
(A) Cephalosporins
