This calculator was prepared for a project funded by EuFMD, and is intended to support the analysis of surveillance data to demonstrate freedom from FMD. Nevertheless, it is a generic calculator and can be used for other diseases as well.
This tool calculates the cumulative probability of freedom from disease, based on the analysis of herd-level risk-based surveillance data over time (with varying probabilities of introduction over time). It allows for one dichotomous herd-level risk factor, one dichotomous animal-level risk factor, and up to three surveillance components with different sensitivity:
As detailed herd-level data is required for multiple surveillance components, this tool uses two types of data input:
Once data is pasted, click the submit button, then view the results of the analysis at the top of the page.
