A: world map illustrating the geographic distribution of studies reporting on mass of waste. World map illustrating the geographic distribution of studies reporting on mass of waste. Countries reporting on mass of infectious waste (kg/bed/day) are shaded blue, with darkening of the colour gradient as mass of infectious waste produced increases. Countries shaded are Bangladesh (< 1), Morocco (< 1), Nigeria (< 1), India (< 1), Ivory Coast (< 1), Kuwait (1–2), Australia (1–2), USA (1–2), Taiwan (2–3), Iran (2–3) and Jordan (3–4). Several studies conducted in Ethiopia, Iran, and Nigeria reported on infectious waste using units other than kg/bed/day (e.g. kg/patient/day or kg/day) and are not shaded in the diagram. B: world map illustrating the geographic distribution of studies reporting on carbon emissions. World map illustrating the geographic distribution of studies reporting on carbon emissions. All countries reporting on carbon emissions are high-income, and include the UK (3 studies), South Korea, Japan and the USA
