WHAT IS EPI INFO™? Introduction

What is Epi Info™?  A suite of free data management, analysis, and visualization tools designed specifically for the public health community.  Features include: o Rapid electronic form creation & data entry o Statistical analysis o Mapping & visualization  Used extensively throughout CDC, domestically and internationally.

System Requirements  Generally, any Windows computer that has recently run Windows Update.  Specifically: o Windows XP, Windows Vista, Windows 7 o.NET Framework 4.0 o 256 MB of RAM

Epi Info™ 7 – Core Principles  Free  Easy to use  Flexible o Lightweight & Agile – when responding to emergencies o Robust – when performing large-scale, multi-user data collection  Standards based  No “IT guys” needed in most cases

Form Designer Used to create electronic data entry forms. Templates can be utilized to facilitate form design. The data entry experience can be tailored with intelligence, such as skip patterns, logical branching, and automatic calculations.

Enter Used to collect data into the form. Addresses can be geocoded into latitude and longitude. Data entry follows the Intelligence rules tailored in the Form Designer.

Classic Analysis Used for data management and analysis. Can read data, relate data tables, perform comparisons and run a wide variety of statistics. Supported data types include text files, Excel spreadsheets, Access databases, and MS SQL Server databases. Output is saved as HTML.

Visual Dashboard Used for quick analysis where only minimal data management is needed. Supports almost all of the statistics as Classic Analysis and supports the same data types. Output is saved as HTML.

Maps Used to create case cluster or choropleth maps. Time lapse functionality is supported. Choropleth maps can be generated using shape files or from map servers such as nationalmaps.gov.

StatCalc Basic Statistical Calculator. Can perform analyses of single or stratified two-by-two tables, determine sample size for studies, and more.

OUTBREAK SCENARIO Introduction

Background In May 2012 in the small town of Madison, GA, the long awaited Acme Company picnic took place. Friends and family of employees attended the picnic. There were people who attended the event. The event was catered by a local sandwich shop. The menu had the following choices for sandwiches: Peanut butter and jelly, Reuben, egg salad sandwich, ham and cheese, grilled chicken, and grilled cheese. Salad choices for each meal included Caesar salad, garden salad, or a chef salad. Potato chips were offered a side. Freshly-baked chocolate chip and peanut butter cookies were served as deserts for each meal order. Drink choices were either iced tea or water. Because the event had a large number of attendees, food and deserts were served at two different times (12 pm and 2 pm) to give the shop ample opportunity to make all of the dishes.

Background Over the next few days following the picnic, the Epidemiology department at the county health department became inundated with calls and faxed lab reports of several culture-confirmed Salmonella Enteritidis cases. Most cases were associated with the Acme Manufacturing Company. Because there was a sudden increase in salmonella cases over the weekend, an investigation into a potential outbreak was conducted. A roster of attendees was obtained and each person was contacted. A case was defined as any attendee of the Acme company picnic presenting with diarrhea, abdominal cramps, and/or fever within 72 hours of the picnic. A total of 90 cases met the case definition.
