Sore Throat

Strep, Centor, peritonsillar

Red Flags — Urgent/Emergency Referral

Drooling / unable to swallow saliva
Stridor or respiratory distress
Trismus (inability to open mouth)
Uvular deviation — peritonsillar abscess
Hot potato voice + bulging peritonsillar area
Severe neck stiffness → meningitis
Immunocompromised patient
Symptoms >1 week not improving

McIsaac Score (Modified Centor)

Predicts probability of Group A Streptococcus (GAS) pharyngitis

Age adjustment:

Score: 0

No antibiotic — viral likely

GAS probability: <10% strep

Viral Pharyngitis

Rhinorrhoea / nasal congestion
Hoarseness
Cough present
Gradual onset
Adenovirus, rhinovirus, EBV, COVID-19
Vesicles/ulcers → Herpangina

Management:

Paracetamol / ibuprofen, warm fluids, salt-water gargle, lozenges. No antibiotics.

Bacterial GAS (Strep)

Sudden onset severe sore throat
Tonsillar exudate / pus
High fever (>38.5°C)
No cough or rhinorrhoea
Halitosis
Petechiae on soft palate

First-line antibiotic:

Phenoxymethylpenicillin (Pen V) 500mg BD × 10 days (children: 250mg BD/TDS)
Penicillin allergy: Clarithromycin 250mg BD × 5 days

Infectious Mononucleosis (EBV)

Clinical Features

Severe exudative tonsillitis
Generalised lymphadenopathy
Splenomegaly
Palatal petechiae
Periorbital oedema
Fatigue / malaise

Investigations

Monospot test (Paul-Bunnell)
FBC: lymphocytosis + atypical lymphocytes
LFTs (transaminitis common)
EBV IgM (if mono negative)
Throat swab to exclude GAS

⚠️ Avoid amoxicillin/ampicillin

Causes widespread maculopapular rash in EBV — not a true allergy

Splenic Rupture

Avoid contact sports / heavy lifting for 3–4 weeks. Rare but life-threatening complication.

Peritonsillar Abscess (Quinsy)

Diagnostic Features

Severe unilateral throat pain
Trismus (inability to open mouth fully)
Hot potato voice
Uvular deviation to contralateral side
Bulging of peritonsillar space
Drooling (dysphagia to saliva)

Management

1Emergency ENT referral for needle aspiration or I&D
2IV Co-amoxiclav 1.2g TDS + IV dexamethasone 8mg
3IV fluids if unable to swallow
4Analgesia: IV paracetamol + PO ibuprofen
5Complete 10-day oral antibiotics post-procedure

Interval tonsillectomy if ≥2 episodes

Patient Education Points

Antibiotics only help if GAS confirmed or high-probability
Complications of untreated GAS: rheumatic fever, glomerulonephritis
Complete full antibiotic course to prevent resistance
Return if symptoms worsen, difficulty breathing, or neck stiffness develops
Viral pharyngitis resolves in 7–10 days without treatment
Stay hydrated — warm fluids help more than cold drinks
