DISEASES OF MILITARY IMPORTANCE

Throughout the history of the world, disease has been man’s worst enemy. Probably the most dreadful episode in recorded history was the infamous “Black Death” epidemic of the 14th century, which was responsible for the death of one-fourth of the population of Europe. Other epidemics, though not so dramatic as the plague epidemic, have wreaked havoc upon civilizations and primitive populations as well.

When diseases are present in the general population, the hazard is even greater to armies. Because of the large numbers of soldiers who live in close association with one another--sometimes in a hostile environment and with less than desirable facilities--diseases, once started, can run rampant if they are not immediately checked.

Until World War I, disease took a far greater toll of manpower than did enemy fire. Napoleon Bonaparte, though considered a military genius, lost over 400,000 of his. 500,000-man army which invaded Russia in 1812 to disease and cold injury, while only 60,000 were killed as a result of direct battle injury. In a previous expedition in Haiti, he had lost 20,000 of a 22,000-man force to the ravages of yellow fever.

The U.S. experience has not been without similar tragedies. During the Civil War, more than twice as many men in both the Union and Confederate armies died from disease as from battle wounds. During the Spanish-American War, more than seven men died from disease (primarily yellow fever) to each man who fell in combat.

Improved medical techniques, antibiotics, and research have done much to bring disease, as a military factor, under control; however, hospital admissions due to disease and noncombat injury continue to far outweigh those due to direct battle causes. It is, thus, of the utmost importance that you know and understand the causes and means of prevention of those diseases that are of military importance.

LESSON 1

GENERAL CONCEPTS

Section I. INTRODUCTION

1-1. PURPOSE

The purpose of this subcourse is to discuss the epidemiology, and the control of diseases of actual or potential military importance. The viewpoint is that of the commander and his medical advisors in a war or preparation for war setting.

· The commander has an interest in the health of individuals and groups making initial entry into the Army.

· The commander is interested in the threat to troops from disease endemic or epidemic in areas of the world that is actual or potential battlegrounds or training grounds.

· The commander is interested in non-effectiveness and lost time because of diseases his command is likely to experience under various circumstances.

· The commander’s interest is clear-cut, because his responsibility for the health of those under his command is clearly defined.

· Peacetime incidences and experience rates are important considerations, too, in that communicable diseases, which cannot be eliminated or effectively controlled in peacetime generally, are the ones most likely to become epidemic in war.

1-2. DISEASE AND INJURY IN WARTIME

History shows that disease and injury, as military problems are factors for which the military leader must plan. In Table 1-1, the periods of war listed were ones in which combat was the heaviest. In spite of these concentrated fighting periods, hospital admissions for disease and non-battle injury far exceeded admissions because of hostile action of the enemy. Furthermore, experience reveals that hospital admissions for disease usually exceed hospital admissions for non-battle injury and battle injury combined. For example, of the 81.8 percent hospital admissions for disease and noncombat injury in Vietnam in 1969, only 13.7 percent were for nonbattle injury and 68.1percent were for disease.

1-3. PREVALENCE OF DISEASE IN PEACETIME

Prevalence of disease in peacetime serves as a baseline against which to estimate probable wartime incidence and attack rates. Acute respiratory infections often account for about one-third of the disease admissions among active duty Army personnel.

Normally, the second most frequent cause of admission is nonbattle injury. Diseases of the digestive system account for about 10 percent of admissions. Often mild cases of illness are not seen by the medical service, and asymptotic infections go unreported. This is known as the “iceberg effect.”
