The "Spanish flu" virus of 1918 killed an estimated 50 million people, more than all the deaths in World War I combined. While global public health efforts have greatly improved mortality rates in more modern outbreaks, experts say the next pandemic is a matter of "when," not "if." In this episode, Ian Bremmer takes a look how diseases spread and become global. His guest, Dr. Anthony Fauci, is a leading epidemiologist and director of the National Institute of Allergy and Infectious Diseases at the NIH.
Dr. Fauci breaks down some of the biggest health threats facing the world today: HIV/AIDS, Ebola, malaria, tuberculosis, influenza, and the recent rise in cases of measles brought on by the misguided anti-vaccine movement.
Also on the show: Five years after his Ebola diagnosis made international news, NYC's Dr. Craig Spencer tells GZERO Media what he learned from the experience and what his life is like today.
