Epi Info™ User Guide

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 will remain functional without CDC assistance as long as Windows 11 is supported by Microsoft. This sunsetting 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 sunset date.

If you have any questions, please contact: epiinfohelp@cdc.gov or check our website in the near future for additional updates/information regarding this announcement.

Epi Info™ is a series of freely-distributable tools and utilities for Microsoft Windows for use by public health professionals to conduct outbreak investigations, manage databases for public health surveillance and other tasks, and general database and statistics applications. It enables physicians, epidemiologists, and other public health and medical officials to rapidly develop a questionnaire or form, customize the data entry process, and enter and analyze data.

Epi Info 7 is free of charge and can be downloaded from the CDC website at http://www.cdc.gov/epiinfo.
