THE INFLUENZA PNEUMONIA PAN- 
DEMIC IN THE AMERICAN ARMY 
CAMPS DURING SEPTEMBER 
AND OCTOBER, 19181 
THE pandemic of influenza which has been 
prevalent in Europe and which swept over the 
United States in the spring of 1918, causing 
much suffering and disability in industrial 
plants and loss of training time in American 
army camps, reappeared with greatly intensi- 
fied violence in September and October. 
Within a month of its recognition it had been 
reported from nearly every quarter of the 
United States, civil and military. 
The army and navy camps suffered severely 
from the outset. Rarely before in the history 
of war has infection exhibited a more explosive 
character or has so large a proportion of troops 
been infected in camps under conditions of 
abundant shelter and food and freedom from 
the strains and anxieties of conflict. The epi- 
demic has been attended by an unusual fa- 
tality. 
The data and deductions contained in this 
report are such as are warranted by daily tele- 
grams and other sources of information col- 
lected during the course of the pandemic. The 
final and complete statistics will not be avail- 
able until after the outbreak is completely over. 
During the period September 12-October 
18, 1918, inclusive, there were 274,745 cases of 
influenza reported among the troops in Amer- 
ica. During the same period there were 46,286 
cases of pneumonia and 14,616 deaths. 
The incidence of influenza and pneumonia 
among all troops in the United States, week 
by week, from the outbreak to and including 
October 18, 1918, follows:
