Did you know?

The bronchial tubes carry air into the tiny branches and smaller cells of the lungs. In bronchitis, the tubes become sore and you develop a deep cough. Bronchitis caused by bacteria can be treated with antibiotics, but there's no drug treatment for the more common kind caused by a virus. A bout of bronchitis may involve a couple of weeks of coughing (with no laughing allowed), weakness, and loss of energy and interest in doing things. Apart from that, bronchitis is rarely serious—at least if it doesn't progress to pneumonia.

Note: The term bronchitis was apparently introduced into English by the British physician Charles Badham (1780-1845) in Observations on the Inflammatory Affections of the Mucous Membrane of the Bronchiæ (London: Callow, 1808), though the word had been used earlier (as a Latinate synonym of Luftröhrenästentzündung) by the German physician Johann Christian Stark (1753-1811) in Handbuch zur Kenntnis und Heilung innerer Krankheiten des menschlichen Körpers (Jena, 1799), pp. 144, 167.
