Open defecation represents a major social and health burden for individuals, families and societies. India alone accounts for approximately 60 per cent of the global population defecating in the open, with the majority residing in rural India. Open defecation spreads diseases such as diarrhoea, schistosomiasis and trachoma and results in stunting and malnutrition of children. It can be dangerous and represent an affront to the dignity of vulnerable groups such as women, adolescent girls, the elderly and individuals with disabilities.

Community health workers are key frontline health paraprofessionals who have the potential to enhance the World Health Organization’s Option B+ strategy to eliminate mother-to-child transmission of HIV.

Although HIV testing, care and treatment coverage have been improving in Sub-Saharan Africa (UNAIDS) 2012), significant numbers of HIV-positive individuals still drop out of HIV care at various stages along the care continuum.

This brief is based on a forthcoming systematic review on Short-term WASH interventions in emergency response: a systematic review, by Yates et al. The review synthesised findings from 106 published and grey literature papers that evaluated 114 WSAH interventions across 39 low- and middleincome countries. The current state of evidence shows that most of the available evidence addresses the question of whether or not these interventions works, but little addresses long-term effectiveness or if the intervention had the intended impacts or not.

Executive Summary


Humanitarian actors have a responsibility to ensure that assistance is provided in a way that minimizes risks and maximizes benefits to people affected by crisis.
