This right here is a prime example of misunderstanding correlation vs. causality.
Fresh water and sewage infrastructure doesn't "cure" any disease. It simple makes it more difficult for the disease to spread through populations.
All of these graphs and bullshit statements in the OP are making that mistake. It's like if you lived in the Alien universe and said "Does killing the xenomorph even work? Look, all these people who aren't in the same room with it are completely fine."
It's pretty obvious that an increase in sanitation and hygiene goes a long way in preventing the spread of disease. Why do you think doctors say that the best way to avoid getting sick is to wash your hands? But having clean drinking water and access to soap doesn't inoculate your body against a disease.
Fresh water and sewage infrastructure cured almost everything.
