I’d be incredibly surprised if an Ebola case turned up from Sudan. Considering Sudan has not had an Ebola outbreak since 2004, and it is really far away from the affected countries, any such case would be from a new and different outbreak.
SUDV is its own strain and was the first known breakout event; there have been multiple outbreaks since 1976. Interestingly, the EBOV outbreak in Zaire was concurrent with the SUDV outbreak in 1976, so maybe history is repeating itself. Or maybe — more likely — it’s hysteria.
