The International Meeting on Emerging Diseases (IMED 2014) is organized by the International Society for Infectious Diseases (ISID) and its Program for Monitoring Emerging Diseases (ProMED-mail). Emerging infectious diseases are at the center of the world’s attention. The threats posed by pandemic influenza, bioterrorism and the realization that new infectious diseases may be recognized at any time, in any place, have dramatically raised our awareness and our need to understand emerging pathogens. What are the most important emerging disease threats? What biological, ecological, social and other factors lead to their emergence? How can we quickly detect their occurrences in order to respond in timely and appropriate ways? This meeting will fully embody the “one health” model of emerging diseases, recognizing the commonality of human and animal health.
