Impact of Differential and Systematic Diagnosis of Dengue, Chikungunya and Malaria on Patient Management and Antibiotic Use in West Africa

"For patients managed in an intervention site, a diagnostic test for dengue and chikungunya using VIDAS® as well as a screening test for malaria will be carried out. An awareness campaign on the use of VIDAS® diagnostic tests will be implemented as well.~The diagnosis will be based on the patient's clinical symptoms, the biological results of the VIDAS® tests for dengue and chikungunya, as well as the results of the tests for malaria."

"For patients managed in a control site, the standard of care practices will be applied in the case of a febrile condition of undetermined etiology. This includes clinical diagnosis and, where appropriate, the use of routinely available diagnostic tests. At the end of the study, the collected samples will be tested using VIDAS® differential diagnosis tests to estimate the number of cases of dengue and chikungunya that have not been correctly diagnosed."
