The 7-1-7 Alliance hosted a training series for Atlanta-based staff of the U.S. Centers for Disease Control and Prevention. A first virtual training session introduced the 7-1-7 target, its central role in the WHO Early Action Review guidance, and how 7-1-7 fits into key components of the global health security framework. In a two-day, in-person workshop, 50 CDC staff members then took a deeper dive into how countries are using the target and received training on how to train other teams, CDC country office staff and Ministry of Health staff on the 7-1-7 target.
