The World Health Organization (WHO) is also dedicated to this end, and through its Programme of Action on Worker ' s Health has sought to protect and promote the health of working populations throughout the world. In reaching toward these objectives, NIOSH and WHO have been able to collaborate on several projects . One project has now resulted in this text, A Joint Publication on Teaching Epidemiology in Occupational Safety and Health. This volume focuses on the need to train occupational epidemiologists in the recognition and evaluation of occupational diseases and injuries. It is a training tool that uses the case approach to instruct epidemiolgists. It is with pride that we publish this boo of case studies ~ an aid to both epidemiologists and the many work rs w 0 will benefit f o'/t'eir services. ,! ,, .
