The author was a researcher at Fujitsu. He uses the AIDS virus in comparison with simian analogues to shed light on the nature of immune system and the effects that the virus has on compromising its function. The book is written for educated average readers who are interested in science. It is amply illustrated with figures to clarify the workings of the immune system and explain riddles such as why some individuals who engage in high risk behavior do not come down with AIDS, why some carriers don't manifest symptoms, and why chimpanzees don't get AIDS.
