One of the important landmarks in man's struggle to conquer disease was the invention of the microscope, generally attributed to Anton van Leeuwenhoek of Holland. Leeuwenhoek described the appearance of protozoa to the Royal Society of London in 1673. Thus, the world became aware of microbial life. Subsequently, Louis Pasteur, Lord Lister, Robert Koch, and others established the role of microorganisms as the causative agents of many diseases and developed techniques for determining the etiology (cause) and preventive measures for many previously uncontrolled diseases.


During the period 1893--1902, several important events occurred in military medicine that benefited not only the Army, but mankind in general. Under the direction of Army Surgeon General George Sternberg (also known as "The Father of American Bacteriology"), Walter Reed, William Gorgas, and other medical officers made dramatic progress in the etiology and control of typhoid fever, malaria, and yellow fever.


This subcourse introduces the basic principles of disease transmission and epidemiology--principles which were used by Reed and Gorgas and which are in use today. It also introduces the student to the study of the microbiological agents, which are important from a military and public health viewpoint.


Subcourse Components:


This subcourse consists of three lessons.

Lesson 1, Introduction to Disease Transmission and Epidemiology.


Lesson 2, Public Health Microbiology.


Lesson 3, Practical Application of Microbiology
