Educated people in the twenty-first century may find it hard to believe that two hundred years ago people did not link illness to problems in the environment. We all know that in London drinking polluted water caused many deaths from cholera.There was a clue to its cause because it always started in the poor neighbourhoods. Then it spread to the richer areas as the servants passed it on.Many doctors suspected that polluted water was to blame and clean water was the cure. John Snow`s investigation proved that the dirtier the water, the more severe the illness. So the government and the doctors concluded that water must be purified.They instructed people to remove the handles from pumps if the water was infected.Thus cholera was defeated in the end.
