Viral growth that we don't want

I read this just now: "High risk Ebola could reach France and UK by end-Oct, scientists calculate" - http://www.trust.org/item/20141005111355-ecbij/?

This is getting quite scary. Is there something I (an individual) can do to help contain Ebola? (Serious question).

In my work I talk about viral growth all day (I consult startups), but this is the viral growth that we all don't want. What can we (HN) do to help the world with this (Spread of Ebola)?
