What is the diagnosis and management for a 25-year-old male with no significant past medical history, presenting with rhinorrhea (runny nose), headache, fatigue, and sneezing for 2 days?

Diagnosis and Management of Acute Viral Upper Respiratory Infection

Diagnosis

This is an acute viral upper respiratory infection (common cold/viral rhinitis), given the 2-day symptom duration with rhinorrhea, headache, fatigue, and sneezing in an otherwise healthy young adult. 1, 2

The clinical presentation is classic for viral rhinitis:

• Symptoms present for only 2 days strongly indicate viral etiology, as bacterial infections typically require ≥10 days of persistent symptoms without improvement 3, 1
• The constellation of runny nose, sneezing, headache, and tiredness represents the typical inflammatory response to viral infection 3, 4
• No antibiotics are indicated at this stage, as the vast majority of acute upper respiratory infections are viral and resolve spontaneously 1, 5, 6

Key Diagnostic Considerations

• Viral rhinitis symptoms typically peak within 3 days and resolve within 10-14 days 1, 4
• Colored nasal discharge alone does NOT indicate bacterial infection and should not trigger antibiotic use 3, 1
• Bacterial rhinosinusitis should only be suspected if symptoms persist >10 days without improvement, worsen after initial improvement ("double sickening"), or present with severe symptoms (high fever >39°C, severe unilateral facial pain) 3, 2

Management Approach

First-Line Symptomatic Treatment

Recommend analgesics, nasal saline irrigation, and adequate rest as primary management. 1, 2

For pain and headache:

• Acetaminophen or ibuprofen 400-600mg every 6-8 hours as needed 1, 2, 7
• These address the most bothersome symptoms and are safe, effective options 1

For nasal congestion and rhinorrhea:

• Nasal saline irrigation 2-3 times daily is highly recommended as it has no rebound effect and helps clear secretions 1, 2
• Adequate hydration to help thin secretions 1
• Humidification of the environment may provide additional comfort 1

Second-Line Options for Persistent Symptoms

If additional symptom relief is needed:

• First-generation antihistamine/decongestant combinations (containing pseudoephedrine and brompheniramine) have shown efficacy in reducing symptoms 1, 2, 8, 9
• Oral decongestants can provide relief but use with caution if patient has hypertension, cardiac disease, or anxiety 1
• Topical nasal decongestants may be used but limit to 3-5 days maximum to avoid rebound congestion (rhinitis medicamentosa) 1, 2

Critical Management Pitfalls to Avoid

Do NOT prescribe antibiotics - they are completely ineffective for viral illness, increase costs, risk adverse effects, and contribute to antimicrobial resistance 3, 1, 6

Avoid:

• Newer non-sedating antihistamines alone (relatively ineffective for common cold symptoms) 1
• Prolonged use of topical decongestants beyond 3-5 days 1, 2
• Basing treatment decisions on nasal discharge color 3, 1

Patient Education and Follow-Up

Provide clear return precautions - instruct the patient to return if: 2

• Symptoms persist >10 days without improvement
• Symptoms worsen after initial improvement ("double sickening" pattern)
• Development of high fever >39°C with severe unilateral facial pain
• Severe headache with neck stiffness, vision changes, or mental status changes

Expected course: 1, 4

• Symptoms should peak within 2-3 days
• Most cases resolve within 7-10 days
• Some symptoms (mild cough, nasal congestion) may persist up to 2 weeks without indicating bacterial infection

Emphasize rest and supportive care as the cornerstone of recovery, as this is a self-limited viral illness 1, 5
