A Look at the Global Spread of Infectious Disease

Journalist Laurie Garrett has recently returned from Zaire, where many people have died due to the spread of the Ebola virus. She is the author of the new book, The Coming Plague: Newly Emerging Diseases in a World Out of Balance. She talks about how people in Zaire changed their behaviors in order to curtail the spread of the Ebola virus.

During the 1898-1904 pox epidemic, public health officials and policemen forced thousands of Americans to be vaccinated against their will. Historian Michael Willrich examines that epidemic's far-reaching implications for individual civil liberties in Pox: An American History.

Since 1994, Dr. Peter Piot been the director of the Joint United Nations Programme on HIV/AIDS and the executive director of U.N. AIDS, the U.N. agency coordinating the fight against the disease. He also co-discovered the Ebola virus. He's considered the U.N.'s top AIDS official. He says Asian countries need to take AIDS prevention and treatment more seriously, as they are only at the beginning of the epidemic. Countries most affected are Thailand, Myanmar and Cambodia. Piot says the HIV/AIDS epidemic has hit India very hard.
