In humanitarian jargon, this term refers to all the means used to provide water, sanitation and hygiene promotion.

According to the Sphere Handbook, the main pathways for pathogens are faeces, fluids, fingers, flies and food. The main objective of WASH programmes in humanitarian interventions is therefore to reduce public health risks by blocking these routes of infection.

This is in line with the IMIF goal of providing quality holistic care to vulnerable people.
