Malaria is the primary reason for consultation, hospitalization and death in health services in Côte d’Ivoire. It is estimated that malaria-related hospital mortality increased from 22% in 2002 to 33% in 2003. In 2010, it was around 50,17% then 43% in 2012. Given the scale of the disease, free impregnated mosquito nets initiated by the national malaria control program have been introduced on the national territory to curb the rising tide of this scourge. The present study, through a logistic regression, aims to analyze in this context of shipping, the main factors that best explain the use of LLNs in these precarious environments. The logit model estimates that, the means of information, the marital status, the knowledge of the causes of malaria, the level of education and the alternatives explain the use of LLNs.
