In this webinar, presenters highlight findings from Toward a Hygienic Environment for Infants and Young Children: A Review of the Literature, share key lessons for implementers, and share the project’s next steps in this area. The review sought to capture the state of knowledge of health risks to infants and young children from fecal exposure in their home environments, focusing on historically underemphasized sources and transmission pathways not disrupted by the traditional suite of water, sanitation, and hygiene measures.
