It is the second day of a 7-day rafting trip in the Grand Canyon. The group consists of 17 passengers and 3 river guides on an 11 meter pontoon raft. The weather is dry, sunny, and hot with a temperature of nearly 105F (40.5C). Before the trip started, the guides educated all passengers on the importance of staying hydrated with plenty of water.
In the mid-afternoon, one of the passengers begins to complain of fatigue and stomach discomfort. Fearful that she is suffering from heat illness and dehydration, the guides instruct her to drink water. More water is also given to the other passengers as a preventative measure.
At noon on the third day, the woman is airlifted to a hospital with diarrhea, vomiting, and confusion. A mere 2 hours later, a second woman begins to complain of nausea. She suddenly becomes disoriented and suffers a grand mal seizure. She is also evacuated by helicopter that very same day.
That evening, at camp, a third woman abruptly begins to vomit and quickly becomes unresponsive. She remains unresponsive and vomiting throughout the night. A helicopter finally reaches camp in the morning and successfully evacuates the third patient.
