Consistent point-of-use water chlorination among households using unimproved water sources and treatment preference in Eastern Ethiopia.

A consistent and correct use of water treatment options is fundamental for health gain from point-of-use water chlorination. In Ethiopia, empirical evidence about the consistent use and preference for by end users is scarce. The current study is intended to explore these issues using Waterguard and Bishan Gari in Kersa Health and Demographic Surveillance Site, Eastern Ethiopia. Data were collected every 2 week for 4 months and analyzed using mixed effects logistic regression. Of 377 households, 31% consistently used Waterguard and Bishan Gari in all the study waves. Product use over time within a household varied based on the perception about the products and the type of products each household received. From the exit assessment, 56% of households stated a preference for Waterguard significantly different from 5.6% of households that stated a preference for Bishan Gari. An intervention for consistent use beyond their availability and accessibility to end users is needed.
