Epi Info

A set of free, public domain software tools offered by the Centers for Disease Control & Prevention (CDC) that can generate epidemiologic statistics, tables, graphs, and GIS mapping. Epi Info is used worldwide for the rapid assessment of disease outbreaks; for the development of small to mid-sized disease surveillance systems; as ad hoc components integrated with other large scale or enterprise-wide public health information systems; and in the continuous education of public health professionals learning the science of epidemiology, tools, and techniques.
