INFUSUM 



Influenza (in-flu-en' -zah) [Ital., an influence, formerly 

 thought to be due to the stars]. A specific, conta- 

 gious, epidemic affection characterized by catarrhal in- 

 flammation of the mucous membrane of the respiratory 

 tract, accompanied by a muco-purulent discharge, 

 fever, and prostration. There is a strong tendency to 

 the development of broncho-pneumonia. At times 

 symptoms referable to the gastro-intestinal system pre- 

 dominate ; at other times the symptoms are mainly re- 

 ferred to the nervous system. The aged, weak, and 

 young often succumb. The disease is popularly called 

 by its French name, la grippe. See Bacillus of In-
