The goal of branchingprocess is to quantify outbreak risk posed by
individual importers of a transmissible pathogen. Input parameters of
negative binomial offspring distributions for the number of
transmissions from each infected individual and initial number of
infected. Calculate probabilities of final outbreak size and generations
of transmission. A full description and derivation of the mathematical
results implemented in these functions can be found in the following
manuscripts:

Work to create this software tool was made possible by cooperative agreement CDC-RFA-FT-23-0069 from the CDC’s Center for Forecasting and Outbreak Analytics.
