    Acute Nasopharyngitis – A Common Illness During Seasonal Transitions

    Update date: 16-05-2025
    52

    Acute nasopharyngitis is a common condition that can affect people of all ages, especially during seasonal changes. It usually has a sudden onset and causes discomfort. If left untreated or improperly managed, it may progress to chronic pharyngitis or lead to serious complications. Let’s explore the symptoms, causes, and prevention methods with H PLUS International Medical Center to better protect your health.

    1. What is Acute Pharyngitis?

    Acute pharyngitis is inflammation of the throat lining lasting less than four weeks, often triggered by abrupt weather changes. While it can occur year-round, it is more frequent during seasonal transitions, especially in children, and is often associated with tonsillitis or adenoiditis.

    The primary causes are viruses (e.g., influenza, measles) or bacteria such as streptococcus or pneumococcus. Environmental factors like pollution, smoke, and sudden weather changes also increase the risk.

    The condition typically starts suddenly with symptoms such as high fever (39–40°C), sore throat, difficulty swallowing, pain radiating to the ears, dry cough, runny nose, hoarseness, and swollen neck lymph nodes. In people with strong immunity, symptoms usually improve within 3–4 days. However, in those with weaker health, the illness can persist and lead to dangerous complications.

    2. Serious Complications of Acute Pharyngitis

    If not treated in time, acute pharyngitis can result in several serious complications affecting overall health:

    • Acute glomerulonephritis: A non-purulent kidney condition causing swelling, hypertension, hematuria, and proteinuria. It can resolve in about six weeks with close monitoring.

    • Acute rheumatic fever: Triggered by streptococcal infection, it affects major joints (knees, ankles, wrists, elbows), causing swelling, heat, redness, and pain. Untreated, it may damage joint membranes and impair long-term mobility.

    • Rheumatic heart disease: Infection may spread to the heart, damaging the inner lining, myocardium, or pericardium. This can lead to serious conditions such as valve regurgitation, stenosis, endocarditis, and even death.

    • Localized complications: Including abscess or cellulitis around the throat, tonsils, or pharyngeal wall, especially in young children.

    • Adjacent organ complications: The infection can spread to nearby areas, causing sinusitis, otitis media, or laryngitis. If it persists, it may progress to tracheitis, bronchitis, or pneumonia, increasing the risk of more severe outcomes.

    3. How to Prevent Acute Nasopharyngitis?

    To reduce the risk of acute pharyngitis, especially during weather transitions, follow these prevention tips:

    • Maintain oral, nasal, and throat hygiene: Brush teeth after meals, before bedtime, and after waking. Use saline or antiseptic mouthwash as recommended to remove harmful bacteria.

    • Bathe with warm water and stay warm: People prone to recurrent pharyngitis should bathe in warm water, dry off quickly, and avoid exposure to cold air or fans while damp. In colder seasons, especially in the morning and at night, wear warm clothing and protect the neck, hands, feet, and chest—especially for young children.

    • Limit exposure to sources of infection: Avoid close contact with individuals who have the flu, respiratory infections, or are smoking to reduce viral and bacterial transmission.

    • Follow a nutritious diet: Eat a balanced diet rich in vitamins and minerals from vegetables and fruits, with proper proportions of carbohydrates, proteins, and fats. Drink enough warm water and avoid cold foods like ice cream or ice to protect the throat lining.

    • Vaccination: Get vaccinated against respiratory illnesses to boost immunity and reduce the risk of infection.

    • Care during illness: When experiencing pharyngitis, eat soft, easy-to-swallow foods, increase intake of fruits and vegetables, get adequate rest, stay warm, and avoid close contact with others to prevent spreading the infection.

    Acute pharyngitis is common at all ages, particularly in children, the elderly, and individuals with weakened immune systems. Although the condition may resolve on its own in many cases, prolonged or severe symptoms can result in serious complications. If symptoms persist or worsen, consult an ENT specialist for timely diagnosis and treatment.
