SLEI Model Software
Abstract
The SLEI Model Software displays differential outbreak potential of chronic wasting disease (CWD) in white-tailed deer under the influence of a habitat contaminated with infectious prions. Based on a Susceptible-Latent-Exposed-Infective (SLEI) compartment model by Hanley et al. (2022), the software depicts outbreak behavior (R_0), stable equilibria of the disease compartments, and the elasticities of R_0 with respect to input parameters (Hethcote 2000). Information regarding the differential likelihood outbreak by county (or parish, administrative area, or other) can guide state and provincial wildlife managers in the allocation of disease surveillance resources. The SLEI Model Software includes (redacted) data containing the cumulative cases of CWD by county in Tennessee, USA, but the software can be adapted using this example for use in other US states or Canadian provinces.
