VizDR: Microbial Dose Response Modeling and Visualization Tool

The Dose-Response Calculator provides the user with a tool that greatly reduces the work it takes to perform a risk assessment. The tool offers an automated dose response calculator, which the user simply has to select a pathogen and input a dose to generate a completed dose response, this also serves as a model visualizer. An added feature of this application is its connection with the QMRAwiki, which provides a dynamically updated list of pathogens and models that the user can select from. If the user has their own data that they wish to have a dose response model optimized for, then they can do so through this app using the same R code as all dose response modeling manuscripts from CAMRA. Documentation and how to video currently under construction.

Cost-benefit analysis example spreadsheet

We have a simple example of cost-benefit tradeoffs for a scenario of decontamination following an anthrax event. File:RiskMgtAnthraxDeconExample.xls

See also cost-benefit analysis elsewhere in this wiki.

'Beach App': a tool to assist beach closure decisions

This is an Android app (under develoment) that uses weather and hydrologic data from the internet, in combination with data observed at the beach, to determine risk of illness for recreational users.

A demonstration version of this tool is on this wiki.

QMRA apps and tools on other sites

  • MicroHibro is an online tool for microbial risk assessment in vegetables and meat. A draft manual is also available.
  • The GInaFiT tool uses Microsoft Excel to fit several microbial persistence models to data. See also a paper regarding this tool.
