There was a WHO graph published on several threads that indicates that the number of cases appearing AFTER 21 days is NOT zero.

There was an ‘epidemiological tail’ that extended to at least 28 days and likely beyond.

I didn’t bookmark that particular link so I’m looking for it.

Perhaps someone else can post it. I’m pinging pa engineer as I think he was the poster with the graph.

Though not the graph you are seeking, here is a recent article with interesting details which might prove worth bookmarking:

Are the Ebola outbreaks in Nigeria and Senegal over?

Recent studies conducted in West Africa have demonstrated that 95% of confirmed cases have an incubation period in the range of 1 to 21 days; 98% have an incubation period that falls within the 1 to 42 day interval. WHO is therefore confident that detection of no new cases, with active surveillance in place, throughout this 42-day period means that an Ebola outbreak is indeed over.
