From the Document: "As the designated DHS lead for pandemic preparedness and response efforts, the Office of Health Affairs (OHA) has been working with our United States Government partners to improve the Nation's capacity for pandemic planning, prevention, and mitigation efforts at the Federal, state, and local level. As part of this effort, OHA is releasing an executive summary of the DHS H1N1 After Action Report (AAR) to share relevant findings with state, local, territorial, and tribal stakeholders to aid their planning efforts for future pandemics, through the national network of fusion centers and the Lessons Learned Information Sharing (LLIS) portal (www.LLIS.gov [hyperlink]). DHS's engagement in pandemic preparedness activities is built upon the National Strategy for Pandemic Influenza (November 2005) and we coordinate extensively with other federal Departments and Agencies on pandemic preparedness and response issues. The intent of the 2009 H1N1 AAR was to conduct an internal analysis of DHS's actions and effectiveness in preparing for and responding to the 2009 H1N1 pandemic threat. DHS followed planning guidance in the DHS 2009-H1N1 Implementation Plan (I-PLAN), designed to ensure critical mission readiness and protection of DHS personnel and people in the care and custody of DHS from the adverse effects of the H1N1 virus."
