Abstract

Malaria is a disease declared by WHO as a public health problem in developing countries It is a parasitic infection of erythrocytes by a protozoan of the genus Plasmodium transmitted by the bites of female Anopheles mosquitoes. The risk of contracting this disease does not spare any section of the population. This study aims to assess the impact of behavioral changes in the population prone to malaria disease after having implemented preventive strategies such as solid awareness and training in repairing mosquito nets. This is a cross-sectional study conducted from April to June 2017 among children under five years of age whose parents had previously (2 years before) received nets followed by sensitization for better use (cluster 1: 115) plus LLIN repair kits (cluster 2: 121) or none at all (cluster 3 control: 137). Children were randomly selected. Thick and thin blood smears were produced on the same slide according to WHO protocols, hemoglobin was read on Hemoreader equipment and RDTs were also performed. A total of 373 children were examined and sampled. Overall prevalence of anemia was 60%. The overall prevalence of anemia was 60% with no significant difference between the three clusters (p>0.05). Out of 373 slides read by microscopy, 19.3% showed P. falciparum and no others species was identified. The prevalence of malaria in Group 1, cluster 2 and cluster 3 was 22.6%, 4.9% and 29.9% respectively (p<0.001). Awareness more repair kits are probably at the root of the low rate of parasitized children in cluster 2 (p<0.001). This assessment showed a low prevalence of parasitaemia in children whose parents received LLINs and repair kits and were sensitized to better use. The National Malaria Control Program (NMCP) should be more involved in raising awareness of behavior change for better net use.
