Epi Info

Epi Info is a free, open source program for epidemiologists and can be downloaded from the CDC website.

From the CDC Epi Info website (cdc.gov/epiinfo):

Epi Info™ is a public domain suite of interoperable software tools designed for the global community of public health practitioners and researchers. It provides for easy data entry form and database construction, a customized data entry experience, and data analyses with epidemiologic statistics, maps, and graphs for public health professionals who may lack an information technology background. Epi Info™ is used for outbreak investigations; for developing small to mid-sized disease surveillance systems; as analysis, visualization, and reporting (AVR) components of larger systems; and in the continuing education in the science of epidemiology and public health analytic methods at schools of public health around the world.

Attention Epi Info™ User Community!

Thank you for being part of the Epi Info™ Community of Users.

After careful consideration, CDC will be phasing out support for Epi Info™. Product development and technical assistance for Epi Info™ will discontinue after Sept. 30, 2025. The desktop tool could remain functional without CDC assistance as long as Windows 11 is supported by Microsoft. This decision is part of CDC’s realignment of resources to focus on products that support the ONE CDC approach to data modernization in public health strategies. CDC understands that this may impact your operations, and we want to ensure users have ample time to transition smoothly. CDC is committed to assist throughout this transition period. A team has been assembled to ensure smooth sunsetting of support for Epi Info™ with an emphasis on customer experience. The team will continue to offer support and maintenance for Epi Info™ until the phase out date.

The Save Epi Info Project

If there is interest in saving Epi Info, it would be advantageous to find an umbrella organization that would do the following:

Short term – maintenance, minor improvements

1.      Maintain Epi Info in its current state (i.e., support and minor fixes)

2.      Minor enhancements/improvements to current version Epi Info

3.      Work on partnerships with other software groups (e.g., REDCap, R, etc.) to provide interoperability.

Long term – completely modernize Epi Info

1.      Develop a new web-based version of Epi Info/OpenEpi that operates on browsers using HTML, JavaScript, and other web-friendly scripting languages.  On the server would be and analytic/statistical/graphics/database code.  The analytic and graphic capabilities would be improved.  It would be backward compatible with the Windows version of Epi Info.

2.      Ideally through partnerships, the new version would integrate/interrelate with other popular programs, such as REDCap, R, and other programs.

Of course, the big issue is funding – who would fund such a project and for how long?  Would there be ways to generate funds to keep the project moving forward? 

If there is interest, we should bring together like-minded individuals to plan and strategize on saving Epi Info.
