Background: The resurgence of Anopheles funestus, a dominant vector of human malaria in western Kenya was partly attributed to insecticide resistance. However, evidence on the molecular basis of pyrethroid resistance in western Kenya is limited. Here, we reported metabolic resistance mechanisms and demonstrated that multiple non-coding Ribonucleic Acids (ncRNAs) could play a potential role in An.

Here, using DNA-based metabolic resistance markers, we assessed the efficacy of the dual active ingredients net Royal Guard against pyrethroids-resistant malaria vectors in Cameroon, establishing its long-term impact on mosquitoes' life traits after exposure.
Results: Cone assays revealed low efficacy of Royal Guard against field Anopheles populations.

Background: Synergists reduce insecticide metabolism in mosquitoes by competing with insecticides for the active sites of metabolic enzymes, such as cytochrome P450s (CYPs). This increases the availability of the insecticide at its specific target site. The combination of both insecticides and synergists increases the toxicity of the mixture.

Background: Congenital malaria remains a significant public health challenge in Nigeria, particularly in regions with high malaria endemicity. The increased vertical transmission of malaria is partly associated with the high susceptibility of women to malaria during pregnancy. This systematic review aimed to assess the prevalence, characteristics, and treatment outcomes of congenital malaria in Nigeria.

Introduction: To evaluate the impact of a novel design "Star Home" on the incidence of malaria, respiratory tract infections and diarrheal diseases among children, randomly selected households in Mtwara, Tanzania were offered a free, new Star Home. Drawing on longitudinal qualitative research that accompanied the Star Homes study, this article describes the experiences of residents and the wider community of living with these buildings.
Methods: A total of four rounds of face-to-face interviews were undertaken with residents of Star Homes (n = 37), control (wattle/daub) homes (n = 21), neighboring households n = 6), community members (n = 17) and community leaders (n = 6).
