Since the plagues of the Middle Ages, ships have been shown to play a significant role in the global transmission of infectious diseases. In this update of the 1987 and 1967 editions, the World Health Organization presents its latest guidelines on health requirements for ship operations and control measures, such as for food safety and waste disposal. The guide includes a summary table of hazards, control measures, monitoring procedures, and corrective actions for the ship water supply system; glossary; and WHO publications and other references. This is the companion to International Medical Guide for Ships (WHO, 2007). Annotation ©2011 Book News, Inc., Portland, OR (booknews.com)
