In particular, there is a robust and strongly significant negative correlation between the estimated basic reproduction number ($R_0$) and the initial outbreak size, in contrast with the role of $R_0$ as a emph{predictor} of outbreak size.	cache/cord-167454-ivhqeu01.txt	txt/cord-167454-ivhqeu01.txt
