Oh come on - it's not 'third world' in any way whatsoever.
It's a one off isolated incident, which is why it's news at all and not just the norm.
People are getting this water through their taps in their own homes, not trekking miles on foot to find it.
Kids aren't having to miss school so they can go and gather this water.
Women aren't risking rape as they go to gather the water each day on foot.
People can stick on a kettle and boil this water inside their houses. Their warm, dry, safe houses with walls. And ELECTRICITY. They can make the water safe immediately and easily.
If they get sick they can go to the publicly funded GP and get medicine prescribed easily and pick it up readily.
If they get very sick, they can go to hospital and receive treatment, including rehydration.
If they get sick, they are not already so malnourished from starvation that their weak bodies cannot handle the infection.
If their children get sick, they are not already so weak that they'll die from it, like hundreds of other children before them in their families and villages.
None of this is 'third world'. It's just a nasty bug in the water and it's gross and unpleasant. Water companies are taking fat bonuses at the same time as dumping record amounts of sewage into our water as well. Water companies are vile. But this is not a developing nation and no part of this incident is comparable to one. You sound spoiled.
