Spatial patterns

Spatial patterns refer to describing the outbreak in terms of where animals were located (place) when they first showed signs of disease (disease onset). Spatial patterns may assist with finding the source of the outbreak. It is often useful to consider place and time together. This can be done by drawing a plan of the spatial layout of the farm (or population), recording the location and dates when cases occurred. Such a diagram may also give a lead to whether the outbreak is a common source or propagating.
