| Abstract | Control measures in epidemiology rely on estimates of necessary control effort to eradicate a parasite. The estimates are calculated with mathematical models. These models often do not consider spatial aspects like heterogeneous distribution of the hosts or the parasite. However, heterogeneity can be expected to have a major impact on the success of control measures. We take the fox tapeworm Echinococcus multilocularis as an example. The cycle of the parasite includes foxes as definite hosts and voles as intermediate hosts. The adult worm produces eggs which are distributed via the foxes feces. Numerous field studies have revealed that a high proportion of foxes carries the parasite (e.g. 24%, Tackmann et al., 1998) from which a high level of infections in the vole population would be expected. Surprisingly, the lot of tapeworm eggs do not lead to high prevalence in intermediate hosts (<1%, e.g. Eckert, 1996). We investigate potential factors responsible for the observed pattern of prevalences in both hosts using a spatially explicit simulation model (Echi). Our findings suggest that spatial heterogeneity is the key to understanding the observed stability of the parasitic cycle. |
