Invasion of the body by various agents—including bacteria, fungi (see fungus), protozoans, viruses, and worms—and its reaction to them or their toxins. Infections are called subclinical until they perceptibly affect health, when they become infectious diseases. Infection can be local (e.g., an abscess), confined to one body system (e.g., pneumonia in the lungs), or generalized (e.g., septicemia). Infectious agents can enter the body by inhalation, ingestion, sexual transmission, passage to a fetus during pregnancy or birth, wound contamination, or animal or insect bites. The body responds with an attack on the invader by leukocytes, production of antibodies or antitoxins, and often a rise in temperature. The antibodies may result in short-term or lifelong immunity. Despite significant progress in preventing and treating infectious diseases, they remain a major cause of illness and death, particularly in regions of poor sanitation, poor nutrition, and crowding.

Each disease gets a description divided into nine sections:
The size of each section varies considerably. For instance, the reservoir section for smallpox is less than a line long, since this disease is, in theory, only present in the freezers of offcicial laboratories. By contrast, the anthrax entry has a large paragraph on the current reservoir.
The cost of the publication is $US 30. Lower prices are available for members of the APHA.
The full title of this book, as registered in the Library of Congress, is Control of communicable diseases manual : an official report of the American Public Health Association (ISBN 0-87553-242-X).
The book is also available in Spanish and Italian. Many illegal copies have been published in Chinese and Arabic (this made one of the former editors, Dr. Abram S. Benenson, very happy, for it was proof to him that "his" book was really useful).
