Gaynell, I would also like an update. As I was responding to the message, I was phoning the Boston office to alert them if they had not yet seen the message. The Travel Support Desk went into action immediately and I felt sure the situation would be resolved.
As to your question about how TL's handle such emergencies: On a recent OAT trip to Costa Rica, a similar situation occurred. We were in the jungle when a traveler exhibited confusion and disorientation and other symptoms of dehydration. Our TL quickly arranged transport to the nearest clinic for her. (I am sure he informed Boston of the situation.) She rejoined us the next evening, rehydrated and with orders to drink sports drinks at least a couple of times a day. The rest of us took note and at the next town, we loaded up on Gatorade and other sports drinks. You just cannot drink enough actual water to stay hydrated during some seasons and in some climates.
