Two models were developed using different groupings of temporal stages of raccoon rabies in a county. Annual surveillance summaries of animal rabies also suggest a persistent elevation in rabid cats following in the wake of the spreading raccoon epizootic. The density of raccoon rabies cases is illustrated in the main map as a grey scale using the density scale at bottom right. An epizootic algorithm defined a time-series of successive intervals of epizootic and inter-epizootic raccoon rabies. Increased monthly counts of rabid raccoons and skunks and decreasing human population density increased the probability of cat rabies in most models. After the first raccoon epizootic, the risk for cat rabies remained elevated at levels six- to seven-fold above baseline. By removing rabies cases mis-classified as raccoon variant, the exclusive contribution of the raccoon rabies epizootic to risk of spillover infection in cats was shown. The preraccoon variant and the sporadic raccoon variant stages were combined to increase model stability to form a pre-epizootic stage (a+b). A possible exception to this has been the development of rabies in the raccoon dog. Only those cases demonstrated to be infected with the raccoon strain of rabies were included in this study. An indicator variable was included for the temporal stage of the raccoon epizootic in the county of origin for the month of testing. Interaction terms combining positive raccoons or positive skunks with the temporal stage were not significant. In contrast to the earlier models, the number of raccoons testing positive was not significantly associated with rabies in cats. These examples are from corpora and from sources on the web.
