Fig 9. Extrapolated infection trajectory for grand average over 40 countries obtained from the model ${\mathcal{M}}_3$.

Grey dots are historical infection trajectories for 40 countries spanning from January 22nd to May 14th. Posterior means for the flat time points are t_{flat,γ=0.999} = July 5th and t_{flat,γ=0.9999} = July 31st.
