What is pharyngitis, and how can you recognize it?
Pharyngitis is an inflammation of the pharynx—the muscular and mucosal cavity located behind the mouth and nasal passages, which is common to both the respiratory and digestive tracts. It differs fromtonsillitis (which specifically affects the tonsils) in that the inflammation is more widespread. In 70 to 80 percent of cases, pharyngitis is viral in origin and resolves on its own within 5 to 7 days. The remaining 20 to 30 percent of cases, particularly among children aged 5 to 15, are caused by bacteria—primarily group A beta-hemolytic streptococcus (GABHS). Natural products for winter illnesses and throat conditions are available in the store.
- Characteristic symptoms: pain when swallowing (odynophagia)—red, inflamed throat—swollen and tender cervical lymph nodes—fever (higher in bacterial cases) — headache — fatigue — little or no cough (a cough is more indicative of nasopharyngitis or bronchitis)
- Signs suggestive of bacterial pharyngitis caused by GAS: McIsaac or Centor score: fever > 38 °C + no cough + tender anterior cervical lymph nodes + tonsillar exudate (white patches) → score ≥ 3 → rapid antigen test (RAT) recommended before antibiotic therapy
- Pharyngitis vs. tonsillitis: pharyngitis (diffuse inflammation of the pharynx—may include the tonsils)—tonsillitis (predominantly tonsillar inflammation, often with exudate) — In French clinical practice, the two terms are often used interchangeably to refer to streptococcal bacterial infections
- Non-infectious causes: allergies (allergic rhinitis with postnasal drip irritating the pharynx) — gastroesophageal reflux — dry, cold air — active or passive smoking — air pollution
How can pharyngitis be treated effectively?
For viral pharyngitis (the majority of cases), treatment is exclusively symptomatic—antibiotics are ineffective against viruses and unnecessary. Rest, hydration, and pain relievers constitute the standard of care. Amoxicillin is the antibiotic of choice for bacterial pharyngitis caused by SGA—it prevents complications and shortens the duration of symptoms. The duration of antibiotic treatment is 6 days (amoxicillin) according to French guidelines (SPILF 2021).
- Pain relievers and anti-inflammatory medications: acetaminophen (first-line treatment—suitable for everyone) — ibuprofen (if there is significant inflammation—contraindicated during pregnancy and in children under 3 months of age) — antiseptic and local anesthetic lozenges (immediate relief from throat pain)
- Effective natural remedies: honey (antibacterial and soothing properties for the throat lining — 1 to 2 teaspoons, either straight or in a warm herbal tea — not recommended for children under 1 year of age) — warm saltwater gargles (1/2 teaspoon of salt in a glass of water — 3 to 4 times a day — reduces swelling and irritation) — propolis spray or lozenges (antibacterial and anti-inflammatory) — thyme tea (antiseptic for the upper respiratory tract)
- Hydration: Drink plenty of fluids (water, herbal teas, hot broths) — the warmth of the beverages soothes the mucous membranes and reduces inflammation — avoid acidic beverages (fruit juices, sodas) that irritate the inflamed throat
- Air humidification: use a humidifier in the bedroom (40–60% humidity) — dry air worsens throat irritation and prolongs symptoms — this is particularly important in winter with central heating
Complications, Prevention, and When to Seek Medical Attention
Viral pharyngitis does not pose a risk of serious complications if properly managed. However, untreated bacterial pharyngitis caused by GAS can lead to local complications (peritonsillar abscess, otitis media) and, more importantly, systemic complications: acute rheumatic fever (ARF—heart involvement) and post-streptococcal glomerulonephritis (kidney involvement). These complications, now rare in France thanks to antibiotic therapy, remain the primary justification for treating bacterial pharyngitis with antibiotics.
- When to seek immediate medical attention: fever > 38.5 °C persisting for more than 48 hours — difficulty swallowing or opening the mouth — a “hot potato” voice (hoarse, hoarse — sign of a peritonsillar abscess) — white patches or pus on the tonsils — very swollen lymph nodes — difficulty breathing — stiff neck (to rule out meningitis) — very young children (< 3 years old)
- Prevention: frequent handwashing (pharyngitis is spread through droplets and contact) — avoid close contact with sick people — use disposable tissues — ventilate rooms — avoid secondhand smoke (a risk factor for ENT infections in children) — treat rhinitis or a cold promptly to prevent it from spreading to the pharynx
- Children and pharyngitis: Children aged 5 to 15 are most commonly affected by streptococcal pharyngitis — children under 3 years of age rarely develop isolated bacterial pharyngitis — in children, antibiotic therapy prevents acute rheumatic fever (a potentially serious cardiac complication) and reduces contagiousness as early as 24 hours after treatment begins
