
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.

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 150-200 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.
