In Nigeria, providers tend to over-diagnose malaria, leading to an overuse of malaria medicines and potentially insufficient attention to other causes of fever in patients. Breakthrough ACTION learned that providers do not trust negative malaria test results because they believe that malaria is endemic and that there should, therefore, be more positive malaria tests. The project’s solutions sought to increase providers’ trust in malaria tests and to make adherence to tests a default practice in public health facilities. Pilot data showed an improvement in both providers’ beliefs and behaviors.  This country Spotlight provides an overview of how Breakthrough ACTION applied the SBC Flow Chart to develop these solutions.
