Trend of malaria in Senegal from 2010 to 2017

Abstract

Abstract Background In Senegal, many interventions have been carried out in the fight against malaria. Thus, the prevalence of malaria has clearly declined from 2010 to the present day. The objective of this study is to study the factors associated with malaria. Methods Senegal is a country in West Africa. The analyses in this study were based on DHS data from 2010 to 2017 from Senegal. Data from 5 DHS surveys were used (2010-2011, 2012-2013, 2014, 2015, 2016). Malaria prevalence had been studied on the basis of RDT positivity. A multivariate analysis with an adjustment over the years was done. The variables studied were socio-demographic characteristics such as age, socioeconomic level and dwelling place (rural vs. urban), variables related to the type of habitat and the use of mosquito nets. The analyses were done using STATA.15. Results The results showed a reduction in malaria prevalence from 3.01% to 0.8% from 2010 to 2016. The protective factors are belonging to a well-off socio-economic background (middle OR:046 [0.24-0.90], richer OR = 0.37 [0.15-0.93]). The other factors associated with malaria are the fact of living in rural area (OR: 1.7 [1.06-2.89]). Conclusions Despite the decline in malaria prevalence over the years in Senegal, its persistence could be feared if factors related to the socio-economic level are not addressed. Key messages Special attention must be paid to people living in rural areas as part of the fight against malaria. The fight against malaria will necessarily involve the fight for the socio-economic emergence of countries in West Africa.
