Trypanosomiasis refers to two diseases caused by the protozoa called trypanosomes. Trypanosoma cruzi in the Americas causes Chagas disease, affecting approximately 15 million people. Trypanosoma brucei in Africa causes African sleeping sickness, also affecting millions. This book looks at the nature of these potentially fatal parasitic diseases. Microbiologist Don Kruel tells where trypanosomes exist and how they spread and cause illness. Separate chapters focus on the two major diseases they cause; other chapters look at their epidemiology, diagnosis, treatment, and preventive health measures.
