Abstract : This article presents the time series of contacts between individuals of an hospital together with measures of the epidemiological spread of different bacterial strains. This experimental dataset collected on a large scale system, over a long period of time provides an outstanding framework for the analysis of functions defined on graphs. Long term objective of this work is to emphasise relations of causality between structural network dynamics and diffusion modes of bacteria. As a mere illustration, we compare the time spreading of a strain from a localised source with the impulse response of a wavelet on the graph of contacts, at different spatial scales.
