Fig 2. Different types of simulations showing the effect of host population dynamics and seasonal driver on the number of deaths caused by Bacillus anthracis.

A) Simulations without population dynamics and seasonal dynamics B) Simulations without population dynamics C) Simulations without seasonal infection dynamics D) Simulations with population and seasonal dynamics. For all cases we assumed τ = 10, θ = 10 and for simulations with seasonal infection we set b₀ = −30, b₁ = −0.85 and the period was three years.
