The author of this volume has brought together 1,000 pages of up-to-date information on cholera. The 11 listed chapters were printed as separate articles in the Bulletin of the World Health Organization prior to this revision. The effects of cholera on a person, population, community, state, nation, and international affairs and all phases of patient medical care, disease control, and prevention are adequately related in this book. Cholera, which Hippocrates described as a disease entity, has been the cause of six pandemics, some of which extended to the United States, in the past century. Cholera was the cause of 1,000 deaths in Calcutta as recently as 1955.
