PLoS Medicine has published a four-part series on water and sanitation.
The first article argues that the massive burden of ill health associated with poor hygiene, sanitation and water supply demands more attention from health professionals and policy makers.
The second article focuses on water supply and argues that much more effort is needed to improve access to safe and sustainable water supplies.
The third article discusses the importance of improved sanitation to health and the role that the health sector can play in its advocacy.
The fourth article outlines what needs to be done to make significant progress in providing more and better hygiene, sanitation and water for all.
