Ralph R. Frerichs

Ralph R. Frerichs is a retired professor of epidemiology, following a long career at UCLA that included teaching, research and consulting on problems of the world's less-developed regions. His first book, Deadly River, tells the true story of how cholera was brought to Haiti, the French disease detective who traced the origin to peacekeepers of the United Nations, and the reactions that followed. What adds to the uniqueness of Deadly River is an open access website at www.deadlyriver.com (see accompanying title page). Organized by chapter, the website shows maps of what took place, the people who were involved, the epidemiological notions used by disease detectives, and more. When the book ended in 2016, the story continued, as presented in the Epilogue section of the website, ever changing as new events unfold.

For teachers, researchers and other interested in higher resolution material, the website has an extensive PDF site that might satisfy their needs. For those who want more about the history of the United Nations peacekeepers in Haiti, the website provides maps and documents from 2004 when all got underway to October 2017, when peacekeepers end their mission.
