Pandemics and Public Health

Nathan Wolfe travels to the viral hot spots of the world, where viruses first jump from animals to humans. The scientist spends his days tracking emerging infectious diseases before they turn into global pandemics.

Writer Laurie Garrett has been a science reporter for NPR, New York "Newsday," "Omni," and other publications. She wrote the new book, "The Coming Plague: Newly Emerging Diseases in a World Out of Balance." It explores the emergence of new infectious viruses like AIDS and Ebola, and the new strains of known diseases that are resistant to many treatments. Garrett examines the conditions that favor the spread of these microbes and looks at possible solutions to stop the diseases.

Holding immigrants responsible for various health epidemics has been an American pastime for two centuries argues Alan Kraut, Professor of History at American University. Just as the Irish were wrongly blamed for the cholera epidemic in the 1830's so too were Haitians in Miami branded as AIDS carriers in the 1980's. His new book "Silent Travelers: Germs, Genes, & the "Immigrant Menace"" (Basic Books) traces how immigration policy and health care have been affected by xenophobia and public fears of contamination.

Dr. Paul Volberding and nurse Cliff Morrison were on the frontlines of the AIDS epidemic treating patients in the early 1980s before anyone understood what the disease was, or how it was spread. They are now featured in the new documentary '5B'.
