Most of this is taken from the first thread noted for all pre-season vidcaps. We can start there and add more as the season progresses and we get more hints or confirmation regarding the evacuations.

As noted by Mark Burnett, posted at Survivor Fever:

"Last season, we had three evacuations, the most ever in a season. It was the humidity, cuts, people getting infected and then trying so hard on the challenges. But we tend to show most things. As a producer you get worried, but Jeff Probst runs the show, and I know if my phone's ringing at 3 or 4 a.m., it's Jeff and it's not a good phone call."

Then, in the premiere promo for Koh-Rong, we got this verbiage:

Probst: But what none of them know is that they're about to face the most punishing season in Survivor history.

Probst: Medical! Medical!

(this is clearly at a challenge, perhaps the same challenge where Jiffy declares we are going to have an evacuation, call for the chopper!)

(this is Jennifer at Totang beach)


(Note the medic with the hat)

(This is Aubrey and we don't know where she is, the medic is holding the pulse oximeter monitor that would go on her finger).

(Joe with the Dr. laying on a pad, don't know where he is? Challenge, beach? Looks more like at camp?)

Female: It just hurts so bad.

(I suspect this is Jennifer in the Brawn tribe)

Medic: The infection can destroy it in a matter of hours.

(I suspect this is Tai, noting the shorts he's wearing, bathing suit)

(This is the same medic that is seen walking on the beach with Probst)

Probst <talking to Medic>: You are pulling him from the game?

Kyle Jason: My shoulders are just destroyed.

Probst <talking to female player>: We're right here with you, alright? Stay with us. You're gonna be alright.

Female: Oh my God.

Probst: We're going to have an evacuation. Call for the chopper!

Here is the youtube video of the first promo: https://www.youtube.com/watch?v=VucpaxqbgKY

Okay, now I am going to group the vidcaps together...

First we see the medic with the hat and Probst walking onto a beach, most likely a camp. Then we see the same medic talking about the infection, how "the infection can destroy it in a matter of hours", and we see the leg wound, most likely on Tai...I believe these shots go together, one incident:

EPMB noted that the evacuations were from over exertion in challenges, and infections. I think that Tai may be one of the evacuations...?

Next there are the issues with Jennifer at Totang, brawn tribe. We see her crying at night, "It hurts so bad"...

Then in the day time, maybe the next day, medical pays her a visit...

Or, Medical could check her out at camp or a challenge, and then she cries later that night. She could be an evacuation???? It's possible.

Aubrey and Joe, both look like they may be suffering from over exertion or heat/dehydration. They could be candidates for evacuation or earlier elimination.

Now, the big evacuation from the challenge...

I will say that someone goes down HARD at a challenge, this is early, as we still see the survivors around the medics looking in...

We see most likely Tai and Julia in the background, we see the doctor, and the balding medic with facial hair...

then, here they are putting an IV in Caleb....we see the Doctor in the foreground as someone else, the medic, manages the 4 way stop ##### and the IV...

then, I think this is the same time but different angles...a different angle, you can still see Survivors around, the jean shorts are most likely, Julia...We also see the same balding medic with facial hair...

He's adjusting the IV that he may have just put in, you can tell the IV is running as it's open...

Jiffy calls for an evacuation and the chopper...

Here come the chopper guys with the stretcher...(note the chopper guy on the left, carrying the back of the stretcher, light blue tee-shirt)

Here's the chopper guy in this scene, wearing the same light blue tee...

So, it looks like the challenge events are centered around Caleb, and most likely he will be a definitive evacuation. They don't put IV's unless they are taking them out of the game, right? Or, can someone be "re-hydrated" via IV and remain in the game? ETA: They re-hydrate via IV for football players and get them right back in the game....?)

When we see the helicopter get called for, it could be the "same" incident at a challenge, Calab, OR, it could be someone different, a female. Regardless, we see the chopper guys arrive, blue tee shirt, and we see them on the scene.

Finally, there is the evacuation that occurs at night....

When Jiffy asks for confirmation about pulling HIM from the game...

This could be Tai. If he stays in the game when he gets seen for his leg infection, but he opts to stay in the game longer with advice if he becomes feverish, they are to report it ASAP? Or, this could be another guy?

We have a definitive evacuation at a challenge....most likely Caleb.
We have a definitive evacuation at night at camp, a MALE. ?Tai?, ??
We have possible evacuations with a female at a challenge, Jennifer, Joe, Aubrey.
