| Note: S, E, I, H, and R represent the states of the SEIHR model. For the previous infection multiplier for coverage, NI, I, and IH represent no infection, infection without hospitalization, and infection with hospitalization, respectively. A dash (“-”) indicates that the values are self-determined in the absence of relevant references.
