Harvard School of Public Health Dean Julio Frenk joined hundreds of scientists, doctors, and technical experts from around the world to launch the Scientific Declaration on Polio Eradication on April 11. The world is closer than ever to eradicating polio, with just 223 cases in five countries last year. To capitalize on this time-limited opportunity to finally end the disease, a wide range of experts have signed the declaration to emphasize the achievability of polio eradication and endorse the Eradication and Endgame Strategic Plan, a new strategy by the Global Polio Eradication Initiative (GPEI) to reach the end of polio by 2018. The scientists and experts signing the declaration come from more than 75 countries and include Nobel laureates, vaccine and infectious disease experts, public health school deans, pediatricians, and other health authorities.
