> Ebola is deadly if you catch it but it is not very contagious at all

This isn't straight Ebolavirus (Zaire), but this thing [1]. We don't have enough data yet to confirm it spreads like Ebola among humans.

If it was that simple Ebola wouldn’t ever spread and nobody would bother trying to contain it. Instead it’s relatively easy to contain but still requires active effort.

Ebola can mutate and this would no longer be true
