Slide contains text and text boxes linked by directional arrows. On the left most side of the slide is an underlined heading that reads "First Hint of Trouble." Under this heading are three bullets: statistical analysis of data; astute observer; and definitive diagnosis of new or "terrorism" organism. From the top of this bulleted list is an arrow that leads to a text box on the right. Within this text box is the heading "Analysis/Characterization" that is followed by three bulleted questions: Is it an emergency? Quarantine? and Get more antibiotics? Directly below that text box is another that has the heading "Additional Data Collection" which is followed by three bullets: "shoeleather," microchip testing, and decision support at the point-of-care. These two text boxes are linked to each other with semi-circular arrows pointing from the Analysis/Characterization text box to the Additional Data Collection text box. From the Analysis/Characterization text box an arrow and points to the right, to the word "Responses."
On the right hand side of the slide are graphics indicating that data goes from the retail stores to a data center, then to the RODS lab and finally to the Pennsylvania Department of Health.

This slide shows 9 lines of information written in a code using various symbols. Three text boxes highlight zip code, visit time and date, and free-text chief complaint information included among the lines of code.
The text "N/V/D- Chief Complaint" is followed by an arrow that points to the right towards a text box and is labeled "Naïve Bayes Classifier." The text box contains the following information: P (Respiratory|NVD)= .05, P (Botulinic|NVD)= .001, P (Constitutional|NVD)= .01, P (GI|NVD) = .9, P (Hemorrhagic|NVD)= .001, P (Neurologic|NVD)= .001, P (Rash|NVD)= .001, P (None|NVD)= .036.
On the right hand side of this text box is another arrow that points to the right and is followed by the text "GI Prodrome Output."
This slide contains a screen shot of a Web page for Utah's RODS system. At the top of the page is a "Systems Message Log," Information in this log includes date, time and a short note describing any alarm that may be occurring. Below the message log is a series of 8 line graphs. They represent the number of all visits, respiratory, GI, rash, constitutional, hemorrhagic, neurological, and botulinic. At the bottom of the page is a drop-down menu that allows a user to select and view a variety of "counts" or graphs.
This slide contains another screen shot of a Web page from Utah's RODS system. This page is identified at a "Mapplot" and contains a State map that can broken down into many "layers." These layers are identified on the right-hand side of the page as Olympic Village, Healthcare Facilities, Highways, Streets, Water, Landmarks, Airports, Zip Codes, Counties, and Western States. The map also shows information about the number of visits or "prodromes" in each layer. There is a drop-down menu that allows a user to choose a specific category. At the left of the screen is a legend that helps a user to interpret what number of cases each color on the map represents.
