Coverage of any oral rehydration solution (“any ORS,” which included treatment with only ORS or with ORS and RHF) is shown in green; only recommended home fluids (only RHF) is in yellow, and no oral rehydration therapy (no ORT) is in purple. Coverage is defined as the percent of children with diarrhea that fell into each category. Results represent the population-weighted mean of estimates aggregated to the national level.
