Details and patient eligibility


This study aims to evaluate the effectiveness of the use of adapted insecticide-treated mosquito nets combined with extended DHA-PQ-based seasonal chemoprevention for all ages and behavior change communication in reducing the burden of malaria in relation to standards of protection and care among students (taalibés) in the daaras (Koranic schools) of Touba, Senegal.

Full description

In Senegal, young children (mostly boys) may be sent to religious schools (daaras) to learn about the Koran and moral and cultural values. The students (talibés) often live and sleep in crowded conditions and as a result, insecticide-treated net (ITN) use is consistently low due to challenges faced in hanging ITNs as well as difficulty covering multiple children sleeping together. This study will consist of a two-arm cluster-randomized controlled trial to evaluate the effectiveness of an intervention package in urban daaras in Touba City, Diourbel region, Senegal. The intervention package will include vector control through meganets (multiple insecticide-treated mosquito nets sewn together and adapted based on the needs and sleeping situation of the daara), seasonal malaria chemoprevention (SMC) extended to all ages using DHA-PQ, and behavior change communication. Prior to evaluating an intervention, there will be 1) a mapping of the daaras in Touba City, Diourbel Region of Senegal to observe the various structures and types of daaras in order to select typical daaras for the entomological component, and to inform randomization, 2) human behavior observation (HBO) of students (talibes) and teachers (marabouts) in 2-3 daaras selected through the mapping to help tailor the intervention package, and 3) analysis of mosquito behavior observed through human landing catches. Two cross-sectional surveys will be conducted, before and after the intervention, which will include an electronic questionnaire to be sent to the taalibés themselves or to their guardians, a temperature reading, an RDT for participants with a fever at the time of the survey, and a fingertip blood sample to assess parasite prevalence (microscopy and PCR). Qualitative surveys will be carried out using a mixed-method design, consisting of a literature review, in-depth individual interviews, focus groups, and on-site observations. Malaria incidence will be determined from records of community health workers assigned to the daaras who have been trained by the Ministry of Health to identify febrile students, test them for malaria using a rapid diagnostic test and treat confirmed cases with an antimalarial medicine. Additional data on students who seek care from health centers in their neighborhood will supplement the data obtained from community health workers.
