Transmissions inside and outside home and their dependence on age.
(A) The number of new transmissions inside and outside home as a function of time t, averaged over 1000 realizations. Inset: the fraction of transmissions inside and outside home normalized by the total number of transmissions as a function of time t, i.e. ΔI(t|home)/I(T|home) and ΔI(t|outside)/I(T|outside) respectively. (B) The number of new infected individuals as a function of time t in different age groups, i.e. ΔIa(t). Inset: the fraction of infections in different age groups which occur at time t, i.e. ΔIa(t)/Ia(T). (C) The distribution of initial and final infected population across different age groups, i.e. Ia(0)/I(0) and Ia(T)/I(T) as orange and green bars respectively, and the fraction of individuals infected at home in different age groups, i.e. Ia(T|home)/Ia(T) (red bars). (D) The fraction of population infected inside and outside their home according to their professions, i.e. Ip(T|home)/Ip(T) and Ip(T|outside)/Ip(T) respectively.
