SaTScan™ is a software for the spatial, temporal and space-time scan statistics. It is used for:
o Performing geographical surveillance of disease;
o Detecting statistically significant spatial or space-time disease clusters;
o Testing whether a disease is randomly distributed over space, over time or over space and time;
o Evaluating the statistical significance of disease cluster alarms and
o Performing repeated time-periodic disease surveillance for early detection of disease outbreaks.
