Can water supply and sanitation be a ‘preventive medicine’?

World-wide, development agencies have increased their investment in water supply and sanitation as a ‘preventive medicine’to address the growing threat from infectious water-related diseases. The policy briefs draws on the Special issue of Water International (vol. 38. 7) to reveal elusiveness of this approach due to complex and contested institutional terrain. This is complicated with national and international discourses that have focused on household-based technologies and on community-based alternatives without its meaningful local adaptation. The policy briefs call for more intensive research to unravel the complex institutional terrain to improve water supply, sanitation and hygiene for lessening the chances of infectious water-related diseases. Equally important it calls on national and international players to consider the Post-2015 goals as visionary statement, rather than targets, to address the ‘preventive medicine’for improved health. In specific, it emphasis national and international actors to play ‘politics with principle’to achieve an integrated water, sanitation and hygiene approach that takes into consideration the complex institutional terrain to reduce the threat from infectious water-related diseases.
