Figure 5.

Figure 5A is a set of fifteen line graphs titled Algeria, Bangladesh, Central African Republic, Chad, Congo, Cote d’Ivoire, Gambia, Georgia, Ghana, Guinea-Bissau, Iraq, Kiribati, Lao People’s Democratic Republic, Lesotho, and Madagascar, plotting Proportion of population using drinking water contaminated by Escherichia coli, ranging from 0 to 100 in increments of 20 (y-axis) across Wealth quintile, ranging from 1 to 5 in unit increments (x-axis) for Very high contamination greater than 100 Escherichia coli CFUs per 100 milliliter at point of collection, Very high contamination greater than 100 Escherichia coli CFUs per 100 milliliter at point of use, Any Escherichia coli contamination at point of collection, Any Escherichia coli contamination at point of use, and 95% Confidence Intervals. Figure 5B is a set of fifteen line graphs titled Mongolia, Nepal, Nigeria, Palestine, Paraguay, Sao Tome and Principe, Sierra Leone, Suriname, Togo, Tonga, Tunisia, and Zimbabwe, plotting Proportion of population using drinking water contaminated by Escherichia coli, ranging from 0 to 100 in increments of 20 (y-axis) across Wealth quintile, ranging from 1 to 5 in unit increments (x-axis) for Very high contamination greater than 100 Escherichia coli CFUs per 100 milliliter at point of collection, Very high contamination greater than 100 Escherichia coli CFUs per 100 milliliter at point of use, Any Escherichia coli contamination at point of collection, Any Escherichia coli contamination at point of use, and 95% Confidence Intervals.

E. coli contamination of drinking water at point of collection and point of use by wealth quintile in 27 low- and middle-income countries, 2014–2020: (A) Algeria to Madagascar, and (B) Mongolia to Zimbabwe. Wealth quintiles from 1 (poorest) through 5 (richest). Wealth quintiles reflect a relative measure of inequality within each country based on asset ownership. Corresponding numeric data are provided in Excel Table S3. Note: CFU, colony forming unit; E. coli, Escherichia coli; Lao PDR, Lao People’s Democratic Republic.
