What are the types of acute upper respiratory infection?
The types of URIs refer to the parts of the upper respiratory tract most involved in the infection. In addition to the common cold, there are other types of URIs:
Sinusitis
Sinusitis is inflammation of the sinuses.
Epiglottitis
Epiglottitis is inflammation of the epiglottis, the upper part of your trachea. It protects the airway from foreign particles that could get into the lungs. Swelling of the epiglottis is dangerous because it can block the flow of air into the trachea.
Laryngitis
Laryngitis is inflammation of the larynx or voice box.
Bronchitis
Inflammation of the bronchial tubes is bronchitis. The right and left bronchial tubes branch off from the trachea and go to the right and left lungs.
