 This research used Maxent, an ecological niche modeling program, to model eastern equine encephalitis virus, EV, habitat suitability probability based on fatality incidents in equine hosts and sentinel chicken infection data, as well as spatial data traditionally utilized for mapping EEV. The resulting map of habitat suitability expanded on previous risk models by utilizing additional environmental factors to identify areas of higher probability for the transmission of EEV, which can assist in identifying places where there is a higher risk of new cases appearing.
