How Important Are Efforts to Improve Water Quality for Health in Developing Countries?

It's absolutely a necessary component of bringing up the level of public health in any kind of developing country. Clean water is also associated with things like malaria too. You can't have standing water around. This is true for Dengue fever as well it's the same mantra over and over clean water and so, in the case of diarrheal diseases it's really keeping a part drinking water part from waste water and so open sewer and other things like this are public health hazards and much of this is infrastructure problems.
