Flu on Call™ is a new pandemic influenza capability that has been in development since 2011. Flu on Call™ establishes a national network of telephone triage lines that are designed to integrate with state and local preparedness plans. The goals of Flu on Call™ are three-fold: reduce surge on medical facilities, reduce the need for face-to-face provider encounters, and increase access to antiviral medications. In 2016, following two years of testing and refining the system, project partners live tested Flu on Call™ in two jurisdictions over a six week period during peak 2015-2016 flu season. The selected sites were Three Rivers Public Health Department (TRPHD) in Nebraska and the City of Milwaukee Health Department (MHD) in Wisconsin. This panel will convene speakers from CDC, the National Association of County and City Health Officials (NACCHO), TRPHD, and MHD. Panelists will present on project outcomes and lessons learned from the planning and activation of the Flu on Call™ demonstration project.
