1990 - Version 5

1990 Epi Info?, Version 5, featured a manual of 384 pages, that described missing value indicators, linear regression, a variety of graphs, analysis of matched data, a report generator, a relational file system, and features for nutritional anthropometry.


It allowed European date formats and non-English characters in data fields, and became the first version to be widely distributed internationally.


The Turbo Pascal source code was sent to volunteer translators who recompiled and distributed the programs in French, Spanish, and Chinese. An Arabic translation was done as a commercial venture, and the Russian version was done under contract to CDC.


1992 Epi Map, Version 1, was developed by Jeff Dean and Tony Burton in Geneva, with debugging and enhancements by Karl Brendel at CDC. Version 2, developed at CDC, added features for programming what happens after mouse clicks on geographic areas.
