Outbreak!

Off of google news:

Marburg Outbreak

I read about the "discovery" of Marburg virus in The Coming Plague, a readable treatment of emergent and re-emergent infectious diseases. This one definitely belongs in the same boat as the more notorious Ebola... easy to spread via contact, not particularly good prospects for survival upon infection, no vaccine or other prophalactic treatment.

My advice would be, don't go to Angola right now.
