The Navajo Epidemiology Center (NEC) is one of the health programs within the Navajo Department of Health. The NEC was established in 2005 to manage Navajo Nation's public health information systems, investigate diseases and injuries of concern, provide data and reports to help health programs effectively manage programs, respond to public health emergencies, and coordinate these activities with other public health authorities. The NEC’s primary objectives are: data collection, analysis and interpretation; health surveillance; disease control and prevention; and data sharing.
