Epi Info™ Web Survey  Introduction to EIWS  Designing a form to be published to the web  Demonstrations Publishing a Form to the Web Importing Data From the Web

Learning Objectives  After this session the participant will be able to: o Describe the Epi Info™ Web Survey system. o Design a form intended for web publishing. o Set up the endpoint address. o Publish a survey to the web. o Update a survey already published. o Begin a web survey, Finish Later, and Submit. o Import data from a web survey.

Introduction to EIWS  Companion to the Epi Info™ 7 suite of tools  Allows the survey designer to collect information from participants over the internet.  Data collection only – not a data management tool
