Key Events in the History of Epi Info™
Epi Info™ Versions 2 and 3
1987 Epi Info™, Version 2, had a bound manual of 112 pages, a pulldown menu,
the EPED word processor for creating questionnaires, ENTER, ANALYSIS,
an epidemiologic calculator called STATCALC, EPICURVE for plotting
histograms, a MERGE program, and IMPORT and CONVERT programs for
file conversions.
The
TABLES command began to offer statistical output. Note the negative
chi square, probably a result of limitations in integer values in an
early version of Turbo Pascal.
The first versions of Epi Info™ were distributed by Andy,
Jeff, and Tony from their office. Suggestions came from users
in the field and were rapidly incorporated into new versions of the
software.
1988 Epi Info™,
Version 3, came with a 150-page manual, enhanced statistics, and sample
programs, including two outbreaks and a surveillance system. The
programs and manual remained in the public domain, but copies were
also marketed by a commercial firm in Atlanta --USD, Inc.-- without
any special arrangement with CDC. This provided a means of distribution
that did not require copying by CDC office staff or permission to distribute
through government channels.

The graphing of epidemic
curves was a popular feature (despite an optical illusion caused
by the diagonal line pattern). |
