Upper Respiratory Tract

CLINICAL CONTEXT

Upper Respiratory Tract: common infections, assessment, and symptom care

The upper respiratory tract includes the nose, paranasal sinuses, pharynx, and larynx. Its mucosa warms, humidifies, and filters inhaled air while local immune defences limit infection. Anatomical continuity explains why viral illness may begin with rhinorrhoea and sore throat, then produce cough or sinus pressure. For students and clinicians, a regional map helps distinguish uncomplicated viral upper respiratory infection from streptococcal pharyngitis, bacterial sinusitis, influenza, COVID-19, allergic rhinitis, and early lower respiratory disease. The patient’s age, comorbidities, immune status, pregnancy, symptom duration, trajectory, and ability to maintain hydration influence assessment and risk.

Common patient problems

Acute viral rhinitis or the common cold often causes congestion, sneezing, sore throat, cough, headache, and malaise; symptoms generally improve over one to two weeks, although cough may linger. Pharyngitis may be viral, bacterial, irritant-related, or associated with allergy or reflux. A positive group A streptococcal diagnosis matters because targeted antibiotics can reduce complications and transmission; clinical features alone do not always reliably distinguish it from viral illness, so local testing pathways may be appropriate. Acute rhinosinusitis commonly follows a viral cold. Persistent, severe, worsening, or unilateral symptoms, high fever, facial pain, or orbital signs prompt consideration of bacterial disease or complications. Hoarseness can follow laryngitis, but persistent voice change, stridor, or swallowing difficulty needs assessment. Ask about breathing, fever, hydration, exposure, smoking, vaccination, medication, and functional impact.

Conventional assessment and management

Assess general appearance, temperature, hydration, respiratory effort, oxygenation when indicated, nasal and oropharyngeal findings, cervical nodes, voice, and lung sounds if cough or breathlessness is present. Testing should answer a clinical question: rapid antigen or molecular testing may guide treatment for streptococcal infection or circulating respiratory viruses; imaging is not routine for uncomplicated symptoms. Most viral illness is managed with rest, fluids, saline nasal spray or irrigation using safe water, and symptom relief chosen for age, pregnancy, comorbidity, and drug interactions. Antibiotics do not treat viruses and are reserved for a supported bacterial diagnosis or selected higher-risk presentation under local guidance. Analgesics, lozenges, and decongestants require attention to contraindications and age. Prevention includes hand hygiene, respiratory etiquette, staying home while acutely unwell, ventilation, and recommended vaccination.

Complementary approaches and safety

Warm drinks, honey for cough in people older than one year, salt-water gargles, humidified air, and rest may soothe symptoms; they do not eradicate infection or replace assessment when illness is severe. Evidence for supplements, herbal remedies, and high-dose vitamins varies, and products may interact with medicines or be unsafe in pregnancy, liver disease, or childhood. Ask patients what they use without judgment. Urgent assessment is needed for difficulty breathing or swallowing, drooling, stridor, dehydration, confusion, blue lips, severe neck swelling, eye swelling or vision change, persistent high fever, or rapidly worsening symptoms.

Clinical communication and follow-up

Explain the working diagnosis, important alternatives, planned tests, expected course, and specific safety-netting in language the patient can use. Invite questions about treatment goals, capacity, cost, culture, and complementary therapies. Use a professional interpreter when language access could affect consent or understanding, and confirm clear arrangements for timely clinical review in writing. Document the reasoning, reassess response to treatment, and coordinate care across professions when illness affects more than one system. Teaching anatomy is most useful when it supports this partnership: accurate localisation, respectful listening, timely escalation, and a plan that remains responsive to the individual patient.
