We know this when we go to far flung places. It's a risk, always has been.
If you suddenly develop a brain clot in Indonesia your nearest specialist hospital could be hundreds/thousands of miles and hours away. It's a risk we all take when we travel.
They are doing their very best and I bet all the locals are looking out too. Just because the 'official' search can do no more, doesn't mean a local search can't continue.
