they take absolutely no precautions around people that are obviously ghastly ill and infectious.

Given their level of resources, what precautions would you take, oh brilliant one?

[Major Matt Mason]

If you see people all around you dying after just basic contact with other infected people, pretty sure it doesn't take a "brilliant one" to figure out that it isn't wise to be in close proximity to the sick. For that matter, you don't get on a plane and travel halfway across the world knowing that you could be infected and could infect others.
