For the record, ALPA is pretty clear about this. If you end up with a serious disease in a foreign country, your best plan is to get out.
Yeah, all kinds of crazy stuff could happen when getting treated in a third world banana republic country, look at this case where 40,000 patients were exposed to Hep C. Whoops, it happened in Nevada.
ALPA sucks, I'm not taking advice from them. 99% of the medical treatments out there you can get in any western country. The other 1% your insurance won't cover, so you are SOL anyways.
