Diagnosis and Management of Cold Weather-Associated Sore Throat
Most Likely Diagnosis
Your sore throat that started with cold weather onset is most likely viral pharyngitis, which accounts for 65-85% of acute sore throat cases and commonly occurs during winter months. 1, 2
Diagnostic Approach
Clinical Features Suggesting Viral Etiology
The timing with cold weather strongly suggests a viral upper respiratory infection, as these infections predominantly occur during colder months. 1 Look for these viral indicators:
- Presence of cough, runny nose (coryza), or hoarseness 1, 2
- Conjunctivitis (red eyes) 1, 2
- Diarrhea 1, 2
- Gradual onset rather than sudden 1
When to Consider Bacterial (Streptococcal) Pharyngitis
Apply the Centor criteria to determine if testing for Group A Streptococcus is needed: 1, 2
- Fever by history (1 point)
- Tonsillar exudates (1 point)
- Tender anterior cervical lymph nodes (1 point)
- Absence of cough (1 point)
If you have 0-2 Centor criteria: This is viral pharyngitis—no testing or antibiotics needed. 1, 2
If you have 3-4 Centor criteria: Perform rapid antigen detection test (RADT) or throat culture to confirm streptococcal infection before prescribing antibiotics. 1, 2
Critical Pitfall to Avoid
Do not assume all winter sore throats need antibiotics. The seasonal timing actually increases the likelihood of viral causes, as respiratory viruses including rhinovirus, coronavirus, adenovirus, influenza, and respiratory syncytial virus peak during cold weather. 1, 2
Treatment Recommendations
For Viral Pharyngitis (Most Likely in Your Case)
Take ibuprofen or acetaminophen (paracetamol) for pain relief—these are the most effective treatments available for viral sore throat. 1, 2
- Symptoms typically resolve within 7 days without antibiotics 2, 3
- Maintain adequate hydration with cool liquids 4
- Throat lozenges may provide additional symptomatic relief 4
If Streptococcal Pharyngitis is Confirmed
Only if RADT or culture confirms Group A Streptococcus AND you have 3-4 Centor criteria, then penicillin V twice or three times daily for 10 days is the first-line antibiotic. 1, 4, 2
The modest benefits of antibiotics in confirmed streptococcal pharyngitis must be weighed against side effects, antimicrobial resistance, and costs. 1 Antibiotics are not needed to prevent complications like ear infections or sinus infections in most cases. 2
When to Seek Further Evaluation
Seek immediate medical attention if you develop: 4, 5
- Severe difficulty swallowing or breathing 2
- Drooling, neck swelling, or "hot potato voice" 4
- Unilateral tonsillar swelling 5
- Persistent high fever with severe symptoms 5
If your sore throat persists beyond 3 weeks, you require laryngoscopy evaluation to rule out serious pathology, as this exceeds the expected duration of viral infections. 5
