Abstract
State and local collaboration is critical to effective preparedness and response planning. Through various assessments, the National Association of County and City Health Officials (NACCHO) is tracking the way in which local and state public health agencies are coordinating their planning efforts to ensure adequate bioterrorism and emergency response capacities. NACCHO's analysis of planning provides a case study of effective and ineffective collaboration. NACCHO intends to share these lessons to provide local and state public health agencies with strategies for enhancing collaboration in the future.
