Long-term trends in <em>Anopheles gambiae</em> insecticide resistance in Côte d'Ivoire (Publications)
for ITNs. The rapid rise in insecticide resistance in African malaria vectors has raised alarms about the sustainability of existing malaria control activities. This problem might be particularly acute [...] BackgroundMalaria control is heavily dependent on the use of insecticides that target adult mosquito vectors via insecticide treated nets (ITNs) or indoor residual spraying (IRS). Four classes of insecticide
Comparison of detection methods to estimate asexual <em>Plasmodium falciparum</em> parasite prevalence and gametocyte carriage in a community survey... (Publications)
BACKGROUND: The use of molecular techniques to detect malaria parasites has been advocated to improve the accuracy of parasite prevalence estimates, especially in moderate to low endemic settings. Molecular [...] carefully evaluated. Light microscopy (LM) and rapid diagnostic tests (RDT) are commonly used to detect malaria infection in resource constrained areas, but their limited sensitivity results in underestimation [...] identified by PCR. Thus, LM is not a sufficiently accurate technique...
Resistance of <em>Anopheles stephensi</em> to selected insecticides used for indoor residual spraying and long-lasting insecticidal nets in Ethiopia (Publications)
BACKGROUND: Malaria, transmitted by the bite of infective female Anopheles mosquitoes, remains a global public health problem. The presence of invasive Anopheles stephensi, capable of transmitting Plasmodium [...] 2016. The ecology of this mosquito species differs from that of Anopheles arabiensis, the primary malaria vector in Ethiopia. This study aimed to evaluate the efficacy of selected insecticides, which are [...] are used in indoor residual spraying (IRS) and selected long-lasting...
Co-infection of the four major <em>Plasmodium </em>species: effects on densities and gametocyte carriage (Publications)
BACKGROUND: Co-infection of the four major species of human malaria parasite Plasmodium falciparum (Pf), P. vivax (Pv), P. malariae (Pm), and P. ovale sp. (Po) is regularly observed, but there is limited [...] (95% CI: 0.95, 1.79) for gametocytes. This excess co-infection risk was partially attributable to malaria infections clustering in some villages. Pf-Pv-Pm triple infections were four times more frequent
Local concepts of anemia-related illnesses and public health implications in the Taabo health demographic surveillance system, Côte d'Ivoire (Publications)
newly recruited ones. Malaria und nutritional issues as understood and managed by the population differed from definitions and recommendations provided by the health system. Malaria was not acknowledged [...] which in turn might affect their health status. Local terminology and beliefs about anemia and malaria should be carefully considered when developing health intervention and education programs. The similarity

Long-term acceptability, durability and bio-efficacy of ZeroVector® durable lining for vector control in Papua New Guinea (Publications)
had previously been installed in 40 homes across four study sites representing a cross section of malaria transmission risk and housing style. Structured questionnaires, DL visual inspections and group [...] at 36-months post-installation, the material and fixtures proved durable and the efficacy against malaria vectors did not decrease. However, the DL material had been removed from over 50% of the original [...] suggest DL may not be an appropriate vector control method for large-scale use in...
Molecular methods for tracking residual <em>Plasmodium falciparum </em>transmission in a close-to-elimination setting in Zanzibar (Publications)
essential for surveillance studies conducted to inform malaria control strategies in close-to-elimination settings. Molecular monitoring of residual malaria infections usually requires a large study size, therefore [...] screening large sample sets represents primarily a research tool that should inform the design of malaria elimination strategies. It may also prove beneficial for diagnostic tasks in surveillance-response
Determinants of bed net use conditional on access in population surveys in Ghana (Publications)
e-treated nets (ITNs) are one of the most effective and widely available methods for preventing malaria, and there is interest in understanding the complexities of behavioural drivers of non-use among [...] access to a net. METHODS: Survey data from the Ghana 2014 Demographic and Health Survey and the 2016 Malaria Indicator Survey were used to calculate household members' access to space under a net as well as [...] households when compared to the poorest category. In 2014, exposure to messages...
