In 2014, the Global Health Security Agenda (GHSA) was launched to “accelerate progress towards a world safe and secure from global health threats posed by infectious disease.” A central component of the GHSA strategy is building the capacity of the global health workforce to prevent, detect, and respond to emerging infectious diseases. Beyond the concentrated attention in the GHSA Action Package dedicated to workforce development, there are milestones throughout the 11 Action Packages which aim to equip a new, transformed, transdisciplinary workforce with the tools and capacities needed for quick detection, action and collaboration across sectors to prevent and stop disease where it starts.
