FloPo, from a medical perspective, what could they do in that 20 min time period? Would they be taking blood samples of everyone? Or just a physical check of wounds? Now that they're all staying at the same camp, would everyone potentially be in danger of having the infection, or just those who were at camp with Peter or Liz? Would they possibly segregate people in any way in terms of sleeping arrangements?

I suspect they are examining everyone, and cleaning wounds up if they can. I wouldn't be surprised if they cultured a few oozing wounds....Joe and Neal. Perhaps, Tai's. I think they wouldn't take any blood samples, but they sure could take their temperatures. And, assess them for fever, chills, malaise, etc.

Depending on what the bug is that is causing the infection, it could indeed be very contagious. They have to consider this, as 2 out of 2 brains had it. They could segregate them...They will most likely talk to them about hygiene out in the wild...soaking those wounds in salt water is a great thing to do...hot packs to the wounds that appear infected would be another good thing to do. Etc.
