Fig 3. Partial rank correlation coefficients (PRCCs) of the ten parameters that influence disease spread.

Parameter values from the ranges in Tables 1 and 2 are considered. Parameters with PRCC larger than zero are positively correlated with 𝓡_eff(t), that is, the effective reproduction number at time t increases as these parameter values are increased. Parameters with negative PRCC will decrease 𝓡_eff(t) as they are increased. Variations in the burial rate and in the transmission rate at funerals have the greatest effect on the reproduction number, in particular at the beginning (t = 0) of the epidemic (a). Fig (b) and (c) show how the relative importance of the parameters on the effective reproduction number changes in time.
