Appendix Figure. Expected proportion of infections caused by an index case (θr1, or PIR1 in the main manuscript) and by secondary cases (θr2, or PIR2 in the main manuscript) until reporting of the index case at PHA, for each studied disease as indicated. θr1 and θr2 are shown as a function of reporting delay median in days. The various line types indicate results for using various standard deviation values for the reporting delay distribution, as indicated in the legend.
