  Description
Intervention Arm

Households with a child 4-10 months old will receive a Cera Maji ceramic water filter for treatment of drinking water.

Ceramic water filter: In total, 120 households with a child 4-10 months old will receive a Cera Maji ceramic water filter for treatment of drinking water at initial entry into the study (intervention group), and 120 households with a child 4-10 months old at initial entry into the study will not receive a ceramic water filter (control group). The study duration will be 6 months. All households in the control group will receive a Cera Maji ceramic water filter when the study ends.

Control Arm Households with a child 4-10 months old at initial entry into the study will not receive a ceramic water filter (control group). The study duration will be 6 months. All households in the control group will receive a Cera Maji ceramic water filter when the study ends.
