Approximate stationary distribution for T, I and V for systems (14) and (16) at t = 30 days with an immune response. Each stationary distribution is fit to a normal curve (solid curve). The standard deviations σburst and σbud for each of the distributions are σburst(T) = 112, σburst(I) = 316, σburst(V) = 1.80 × 104, and σbud(T) ≈ 111, σbud(I) ≈ 344, σbud(V) ≈ 1.30 × 104.
