摘要：The National Environmental Public Health Tracking Program facilitates the linkage of environmental information to health outcomes through development of a national standards-based public health surveillance system that provides useful information to improve where we live and work. State tracking programs have successfully used their tracking networks to identify and educate at-risk communities. Other success stories include endeavours to improve surveillance, support epidemiologic studies, target prevention efforts, and inform policymakers. Future directions include identifying knowledge gaps, developing plans for adding new data sources and collaborators to fill those gaps, and improving application and utility of the Tracking Networks.
