Key Hygiene Improvement Interventions

Hygiene improvement interventions are well defined. Program approaches, while continuing to evolve, have been demonstrated to be effective, as well as cost-effective, in terms of public health impact. Key hygiene improvement interventions include:

• Safe storage and treatment of water at point-of-use, which has been shown to typically result in approximately 30-40 percent reduction in diarrhea prevalence (with a greater range of observed impact)
  


• Optimal handwashing, which can decrease diarrhea prevalence among children by an average of 40 percent
