Article Synopsis
- The study in Bouaké, Côte d'Ivoire, assessed how common asymptomatic and subpatent P. falciparum infections are and compared the effectiveness of three diagnostic tests (light microscopy, rapid diagnostic tests, and quantitative PCR).
- Out of 2313 participants, 97.2% were asymptomatic, with high prevalence rates found; particularly in school-age children, while subpatent infections were more common in older individuals (≥15 years).
- The findings suggest that traditional tests only detect high-density infections, and none of the tested samples showed deletions in the pfhrp2 gene, indicating a need for focused malaria reduction strategies in urban areas.
The emergence of insecticide resistance in vectors mosquitoes poses a real challenge for arboviral-borne disease control. In Côte d'Ivoire, data are available on phenotypic resistance and the presence of kdr mutations in . Therefore, information on metabolic resistance in populations is very scarce.

This study intended to evaluate the operational effectiveness of LLINs on the level of human-vector contact using 1 antibody-based biomarker of exposure to in urban areas.
Methods: This cross-sectional study collected socio-demographic data and use of LLINs from 9 neighborhoods in the city of Bouaké (Côte d'Ivoire).
Background: In malaria-endemic areas, human populations are frequently exposed to immunomodulatory salivary components injected during mosquito blood feeding. The consequences on pathogen-specific immune responses are not well known. This study evaluated and compared the humoral responses specific to merozoite stage vaccine candidates of Plasmodium falciparum, in children differentially exposed to Anopheles bites in a natural setting.

To improve the control of the disease, it is critical to identify neighbourhoods where the risk of malaria transmission is the highest. This study aims to evaluate the heterogeneity of malaria transmission risk in one city (Bouaké) in a West African country (Côte d'Ivoire) that presents several levels of urbanization.

This study aimed to evaluate the risk of malaria transmission in an urban area by evaluating the level of human exposure to bites using an salivary biomarker ( Salivary Gland Protein-6 peptide 1 [gSG6-P1] peptide). Two multidisciplinary cross-sectional studies were undertaken in five sites of Bouaké city (three urban districts and two surrounding villages, used as control; Côte d'Ivoire) during the rainy season and the dry season.

- The study assesses the resistance levels of malaria-transmitting mosquitoes, An. gambiae (s.l.), in Bouaké, Côte d'Ivoire, highlighting increasing resistance to various insecticides.
- Using WHO bioassay tests, it was found that mortality rates for mosquitoes exposed to these insecticides ranged from 0% to 73%, with PBO treatment improving susceptibility, particularly to pyrethroids and carbamates.
- The research identified two molecular forms of the mosquito and revealed high frequencies of resistance alleles, indicating a significant challenge in controlling malaria in the region.
