Management of Upper Respiratory Tract Infections

Initial Assessment and Triage

The American College of Physicians recommends determining if an upper respiratory tract infection is viral or bacterial before considering antibiotics, as 98-99.5% of cases are viral 1
The typical duration of the common cold is 7-10 days, and approximately 90% of acute cough illnesses are viral 1
Pneumonia is unlikely if all of the following are absent: heart rate >100 bpm, respiratory rate >24 breaths/min, fever >38°C for >3 days, and abnormal chest examination 1

The American Academy of Family Physicians recommends providing symptomatic treatment for all patients regardless of etiology, including analgesics and antipyretics (acetaminophen, NSAIDs) for pain and fever 2, 1
Intranasal saline irrigation is recommended for nasal symptoms 1
Intranasal corticosteroids are recommended for symptomatic relief 1
Adequate hydration, warm facial packs, and sleeping with head elevated provide supportive benefit 3

The Infectious Diseases Society of America recommends antibiotics for acute bacterial rhinosinusitis (ABRS) if symptoms persist without improvement for >10 days, or if severe symptoms are present (fever >39°C with purulent discharge for ≥3 consecutive days) 1, 3
First-line treatment for ABRS is amoxicillin-clavulanate 875/125 mg twice daily for adults, with a treatment duration of 7-10 days 1, 3
Alternative first-line options for penicillin allergy include second-generation cephalosporins (cefuroxime-axetil) and third-generation cephalosporins (cefpodoxime-proxetil, cefdinir) 4, 3

Clinical follow-up is essential with reassessment at 2-3 days for most URTIs, or 3-5 days for sinusitis on antibiotics, to evaluate response to treatment and potential need for antibiotic therapy 5, 1, 3
If fever >38°C persists beyond 3 days, consider bacterial superinfection and antibiotic therapy 5, 1

Patients should be informed that >90% of acute cough illnesses are viral and self-limited (7-10 days typical duration) 1
Antibiotics will not shorten symptom duration for viral infections 1
Patients should return if fever does not resolve within 48 hours of starting antibiotics 6
Cough may last longer than the duration of antibiotic treatment 6
