The gamma distribution specified is not directly the serial interval but the serial interval minus one, to allow for a gamma distribution (otherwise infectiousness at day 0 could not be handled), see Cori et al. 2013 for more details.

.compute_discretized_infectiousness(k, shapeG = 2.73, scaleG = 1.39)

Arguments

k

Integer. Infex of the time step.

shapeG

shape of the gamma distribution of the serial interval -1.

scaleG

scale of the gamma distribution of the serial interval -1.

Value

value of the infectiousness profile at time step k.
