Until the influenza epidemic swept the country in the autumn of 1918, after devastating the populations of Europe, the disease figures of the American Army had set a new low record both at home and overseas. For the year ending with the first of September, 1918, which covered the time from the first gathering of men in the cantonments, the death rate for all troops in the United States was 6.37, which is a lower rate than that in civilian life for similar ages. But when the plague of influenza, which on its way around the world took a toll of 6,000,000 lives, descended upon the camps and cantonments in the United States the death rate rose to 32.15 per thousand. For the entire term of the war the disease death rate was 17 per thousand in the expeditionary forces and 16 per thousand in the army at home. The comparison of these figures with the rate maintained before the passage of the epidemic shows how deadly it was. During the summer months of 1918 the death rate for the troops both at home and overseas fell to 2.8 per thousand. During the Mexican war the disease death rate was 110 per thousand, during the Civil War in the Northern Armies it was 65 per thousand and during the Spanish-American war 26 per thousand. During the last named war the most important cause of death was typhoid fever, before which medical science was then as helpless as it was during this war under the influenza scourge. It had conquered that menace and typhoid, by its precautions, was almost eliminated from our army both at home and abroad. But notwithstanding the devastations of influenza the disease death rate in the American Army was cut to a lower figure than had been reached by any army in previous wars. The lowest previously recorded was that of the Japanese during the Russo-Japanese war, which was 20 per thousand. The battle death rate of the American Expeditionary Forces was 57 per thousand, considerably higher than it had been in any of our previous wars. In the Mexican war it was 15, in the Civil war in the Northern Armies 33, and in the Spanish-American war 5 per thousand. Overseas, during the eight months ending with mid-October, 1918, only four per cent of the admissions to hospital because of disease resulted in death. Of the wounded and injury cases treated during the same period a little less than nine per cent died and over 85 per cent were returned to duty. Of the American Expeditionary Forces 4,000 were permanently crippled and 125 were totally blinded.
