Upper respiratory tract infections (URI) are one of the most common reasons for a visit to the doctor and one of the main causes for a missed day at school or work. The nose, throat, pharynx, larynx and bronchi constitute the upper respiratory tract. Virus and bacteria contribute to infections like sinusitis (inflamed sinuses), epiglottitis (inflamed epiglottis), laryngitis (enflamed voice box) and bronchitis (inflamed bronchial tubes). Some of the most common symptoms that one experiences are fever, cough, sneezing, runny nose, nasal congestion, fatigue, and headache, trouble while swallowing and wheezing. Diagnosis of the infections is done via a throat swab, lateral neck X-ray, chest X-ray or a CT scan.
