Dr. Colford reviews examples of two studies conducted by his group in Bolivia and in India as a means to review study design strategies for clustered randomized trials and for matched cohort designs applied to the health impact evaluation of water, sanitation, and hygiene interventions. These design approaches have wide generalizability to other infectious disease problems that involve clustered intervention delivery and outcomes.
