The 5th graph is the really interesting one.
It’s definitely drifted since we first encountered it in Zaire. Who knows what tricks it’s picked up since then.
Thanks for posting that info with the graphs. It confirms the CDC 3% variance of this strain with previous Zaire Ebola Virus. That “drift” is not insignificant IMO. May well account for increased hardiness and transmissability.

Might explain the separate repatriation of the two Americans. The Dr having received blood from an Ebola survivor, the other not. Isolate the one from the other and compare samples. That sort of lab work might reveal more than a field lab.
