However, to date, no single study has provided quantitative evidence that the amplification cycle occurs at the local level and that it operates within certain temporal parameters. Here, we use a novel geostatistical and spatial analytic methodology and present the first evidence that the localized unusual space-time correspondence of dead birds models the amplification cycle and that this cycle peaks 15-16 days prior to human onset of West Nile virus infections. During the process of establishing this relationship, we extend the traditional Knox space-time interaction measure to overcome pair-dependency, limitations and use a novel implementation of the kappa non-chance agreement measure to identify the temporal characteristics of the association of bird deaths to human West Nile infections.
