We want to be able to left-center countries on a few different definitions of "start of epidemic". For example here are some operationalization of the "first day of epidemic" that I have seen in the news so far:
1) the 1st recorded death
2) the 3rd recorded death = day 1
3) number of deaths increase at least 3 days in a row
