Before the start of the intervention study we will conduct meetings with the medical staff to explain the intervention and standard study procedure. We will provide information from published sources of the accuracy of 'Paracheck' compared to expert slide reading. Staff will be encouraged to use the RDT result in the same way that they would use a blood slide result of equivalent accuracy. We will consult with the Malaria Control Programme what additional information they would disseminate if they were deploying the tests.
