To add to that, I also saw that they tried giving him penicillin when he was actually slightly allergic to it, which contributed to his physical state when he got pulled. They really did not explain the evac well on the show. It was basically like, "Well, he's starved and dehydrated" but surely everyone else on Survivor is too. Except maybe Stephenie "Big Hongry" Lagrossa in Guatemala.
I'd actually love to know what the policies for medical evacuations are on this show. Other than Michael in Australia, they went so many seasons without anybody being removed and now it's like every season has an evacuation. I know in Australia, Elisabeth's hair was falling out because she was so malnourished but they never removed her, and supposedly two contestants in Africa (Lindsey and Lex) were taken to the hospital to be rehydrated or something without being pulled from the game. But Erik gets dizzy and they're pulling out the stretcher for him even though he was fine the next day at TC.
