WaterAid's report Transforming Health Systems: the vital role of water, sanitation and hygiene, argues that governments must act now to better coordinate between ministries and organisations focused on health and those leading on water, sanitation and hygiene, and ensure water, sanitation and hygiene are properly integrated into national healthcare policies, programmes and strategies. Effective, long-term financing by governments and donors must also be prioritised to ensure these essential building blocks of quality healthcare are sustainable and governments must ensure that progress is properly monitored within the health system.
