It's pretty likely that date of exposure is not really known or knowable with much accuracy for a very large number of cases.
So, probably best to pay attention but also take it with a grain of salt and watch for additional research on incubation (latency) periods.
WHO continues to recommend 14 days for contact followups and advises that the median incubation period appears to be 5-6 days.
