Good hygiene is the single most effective action an individual can take to prevent covid-19 transmission; that is absolutely an important point. Water sanitation and hygiene are a key part of DFID’s work and vital in humanitarian crises. DFID funds the provision of safe water and sanitation in disaster areas across the globe. Since 2015, DFID has helped over 51 million poor people in Africa and Asia get access to a drinking water supply or toilet for the first time. But we recognise there is still more to do.
