How are you using the National Health Security Preparedness Index to ready your community for an emergency? The new Preparedness Innovator Challenge hosted by the Robert Wood Johnson Foundation and the University of Kentucky College of Public Health wants to hear what you are doing or what you plan to do to improve preparedness, health security, and resilience against disaster in your community. Has use of the Index in your community sparked conversations with community leaders? Are you using Index data to identify preparedness gaps? The Preparedness Innovator Challenge is an opportunity for you to help your colleagues by sharing how the Index is helping your community prepare for the unexpected. Teams or individuals with an interest in improving health security and preparedness are invited to apply now.
