I had heard pretty much everyone who goes to Xmas gets the runs at some point. I’m here to tell you this is not the case.
The risk is certainly on Christmas Island, however, and caution is your friend.
The Villages provides purified water in a pitcher in your room. Use it. Use it to brush your teeth. Use it to rise your toothbrush. Use it for anything.
Don’t put water in your mouth in the shower. Just don’t.
I had a phone appointment before I left with the Kaiser Travel Clinic and they got me a 3 pill prescription for antibiotics specific to what I might encounter there. I didn’t need to use them.
It was frequently the case that guides missed days because of GI bugs. Water borne disease is pretty rampant on Christmas and the locals are very much not immune. Many guides powered through their days even with their stomach bugs and would simply excuse themselves to take care of business. It’s life on the island and that guiding money isn’t going to come from anywhere else.
Only one guy out of our 16-17 anglers had any issues and that was minor, treatable with Imodium (which is NOT how you treat sever diarrhea). Caution and prevention is where it is at.
