Bacterial tracheitis is a rare complication of influenza infection. [4] It is the most serious in young children, possibly because of the relatively small size of the trachea that gets easily blocked by swelling. The most frequent sign is the rapid development of stridor. It is occasionally confused with croup. If it is inflamed, a condition ...
Croup (/ k r uː p / KROOP), also known as croupy cough, is a type of respiratory infection that is usually caused by a virus. [2] The infection leads to swelling inside the trachea, which interferes with normal breathing and produces the classic symptoms of "barking/brassy" cough, inspiratory stridor and a hoarse voice. [2]
Epiglottitis is the inflammation of the epiglottis—the flap at the base of the tongue that prevents food entering the trachea (windpipe). [7] Symptoms are usually rapid in onset and include trouble swallowing which can result in drooling, changes to the voice, fever, and an increased breathing rate.
Without involving the nose, pharyngitis inflames the pharynx, hypopharynx, uvula, and tonsils. Similarly, epiglottitis (supraglottitis) inflames the superior portion of the larynx and supraglottic area; laryngitis is in the larynx; laryngotracheitis is in the larynx, trachea, and subglottic area; and tracheitis is in the trachea and subglottic ...
On an X-ray, croup can be recognized by the "steeple sign", which is a narrowing of the trachea. It most commonly occurs in winter months in children between the ages of 3 months and 5 years. A severe form caused by bacteria is called bacterial tracheitis. [12] Tonsillitis is swelling of the tonsils by a bacterial or viral infection. This ...
It is usually caused by viral infections, [10] with bacterial infections occurring almost entirely in children. [11] Most commonly, infections occur with inflammation of other parts of the respiratory tract, such as the larynx and bronchi, known as croup , [ 11 ] [ 10 ] however bacterial infections may also affect the trachea alone, although ...

In children, viral infections such as croup or epiglottitis are frequent causes. [4] Adults are more likely to experience obstruction from enlargement of the tonsils or vocal cord paralysis. [3] Obstructive sleep apnea is the most common chronic cause of upper airway obstruction. [2]
