The following steps will walk you through installing a virtual machine (VM) version of the new OpenESSENCE system for aggregate data collection. The VM contains a fully configured system, so that you can quickly start using OpenESSENCE without a lengthy installation process.


  1. Download and install Virtual Box, which is a tool that you can use to easily stop and start VMs on your computer. Virtual Box is free to download, but you will need administrator privileges on your computer in order to install it. Access the download for Virtual Box from this link: https://www.virtualbox.org/wiki/Downloads.
  2. Click the following link and download the sages-aggregate-alpha.ova VM file onto your computer: https://s3.amazonaws.com/sagesvm/sages-aggregate-alpha.ova
  3. Double-click the VM file. Virtual Box will appear with the option to import the OpenESSENCE VM. Click Import (you do not need to change any default settings).
  4. Once the VM is imported, it will appear in the Virtual Box window in the list on the left hand side. Highlight the VM and click Start (you can ignore the black terminal window that appears).
  5. Open a browser window (such as Internet Explorer or Chrome), and type localhost:9000 in the address bar and press Enter.
  6. Click Sign In and follow the process. You can use your e-mail address as your ID.
  7. Start using OpenESSENCE!

SAGES Mobile

Android smartphones (or simple cell phones) can be used to send surveillance data to a central repository. A customized data entry form, built using Open Data Kit (ODK) Build, is loaded into an Android-based application called SAGES ODK-Collect, a JHU/APL tool which is a modified version of the popular open source ODK Collect Android phone application. SAGES ODK-Collect, in conjunction with the data entry form, enables the collection of surveillance data using a form-based interface on the Android smartphone, and the submission of that data over the SMS protocol.

ESSENCE Desktop Edition (EDE)

ESSENCE Desktop Edition (EDE) is a single-user stand-alone analysis and visualization tool that can be installed on most computers. It is designed to run independently on a single desktop or laptop computer. EDE does not need access to the internet because it ingests data files stored on the same computer. Available analyses include demographic characterizations, temporal and spatial analyses, display of patient level information, geographic mapping, anomalous event detection, and dynamic query capability. Visualization features include: time series charts, pie/bar charts, tables, and choropleth maps.
