Gastrointestinal symptoms were insignificant: 8 patients complained of nausea early in the disease and 6 of them vomited. Diarrhea occurred in only 1 case, constipation being the rule. The spleen was palpable in 21 cases, but this is of doubtful significance, since nearly all the patients came from malarial regions. Jaundice was not noted. Aside from the profound depression, sometimes amounting to stupor, mental symptoms were not noted except in 1 case which showed a mild delirium.

Influenza, although per se a self-limited disease of short duration, frequently leads to the development of serious complications, the most important of which are pneumonia and purulent bronchitis with a varying degree of bronchiectasis. In the group of 100 cases of influenza studied, purulent bronchitis developed in 36 instances, pneumonia in 15; in 3 cases there was lobar pneumonia, in 12 bronchopneumonia. Further discussion of these complications is reserved for the sections dealing with them in detail. Other complications were relatively rare. Otitis media occurred in one case and frontal sinusitis in one. No fatalities were observed among cases of uncomplicated influenza, the deaths that occurred being invariably associated with a secondary pneumonia due in nearly all instances to secondary infection with pneumococci or hemolytic streptococci.
