Figure 2

Multiyear kernel density derived hotspots and standard deviational ellipses shown as ellipsoid shapes. The ellipses illustrate the directionality of anthrax outbreaks across years. Note the size, shape, and overlap of ellipses in different years (colours correspond to the study years). The kernel density defines the spatial distribution of field characterization and active surveillance anthrax outbreaks (2017–2020) densities.
