That the man was returning from Burundi makes me suspect this is not ebola.
Burundi is definitely at risk from this outbreak, but I would expect reports of ebola cases in a nation before a visitor to that nation comes home with it (because visitors are a miniscule fraction of the total population there.) Just statistically, that would be expected.
That is not definitive. It is possible there is unreported community transmission in Burundi, or that this visitor hung out with people who had come from infected regions of Congo, or that this visitor had traveled to nearby countries and contracted ebola outside Burundi. So we should be cautious and watch this report carefully.
Attached is a map of the region. The ebola outbreak is concentrated in Noth Kivu province of Congo.
