As a crucial component of our study, we are providing each selected household with four straightforward tests to detect the presence of coliform bacteria in their drinking water. One of these tests is administered by a trained enumerator during the baseline survey. This hands-on demonstration not only complements the instructional video we have produced but also ensures that each household in the intervention group receives at least one test.
Upon completion, the test is carefully transported to our headquarters in Nairobi using hygienically clean cool boxes. Our principal investigators (PIs) will inspect the results 48 hours after the test has been conducted. The households will be informed of the test results via SMS approximately one week after the test was performed. This procedure has been successfully coordinated with the invaluable support of the Kenyan Ministry of Health. Their assistance has been instrumental in ensuring the smooth execution of our study.
We also thank our local team members and our enumerators for their great work in the field!
