Model-free estimation of COVID-19 transmission dynamics from a complete outbreak

Examines the COVID-19 epidemic transmission tree in New Zealand using detailed case data and contact tracing information, noting it is an unusual dataset because it describes a closed outbreak in which there are no ongoing transmission chains, and many cases are epidemiologically linked to a likely index case. Uses Monte-Carlo network construction techniques to provide an estimate of the number of secondary cases for every individual infected during the outbreak, then applies standard statistical techniques to quantify differences between groups of individuals.
