Fine-scale spatial and temporal heterogeneities in insecticide resistance profiles of the malaria vector,<em> Anopheles arabiensis</em> in rural... (Publications)
differences between districts, regions or countries. However, local heterogeneities in residual malaria transmission imply the need for finer-scale data. This study reports small-scale variations of i [...] villages across two seasons in Tanzania, where insecticidal bed nets are extensively used, but malaria transmission persists. Methods: WHO insecticide susceptibility assays were conducted on female and
Informing new or improved vector control tools for reducing the malaria burden in Tanzania: a qualitative exploration of perceptions of mosquitoes and... (Publications)
CONCLUSIONS: Outdoor transmission is widely accepted as an obstacle to malaria elimination. Larval source management, targeting both malaria vectors and nuisance-biting mosquitoes, is the preferred method for [...] BACKGROUND: The effectiveness of malaria prevention with long-lasting insecticidal nets and indoor residual spraying is limited by emerging insecticide resistance, evasive mosquito behaviours that include [...] to widespread environmental deterioration and lack of effective mosquito...
State of inequality in malaria intervention coverage in sub-Saharan African countries (Publications)
BACKGROUND: Scale-up of malaria interventions over the last decade have yielded a significant reduction in malaria transmission and disease burden in sub-Saharan Africa. We estimated economic gradients [...] in coverage of malaria interventions and their distribution by wealth within and across countries. In most, economic gradients are lacking or favor the poorest for vector control; malaria services delivered [...] Using Demographic and Health Surveys we computed equity metrics to characterize...
The underlying reasons for very high levels of bed net use, and higher malaria infection prevalence among bed net users than non-users in the... (Publications)
even suppress entire populations of malaria vectors that feed predominantly upon humans. Nevertheless, an epidemiological study in 2012 demonstrated higher malaria prevalence among bed net users than non-users [...] against malaria. Houses with well-screened windows, with doors that shut properly, and that use insecticidal sprays against mosquitoes, were said not to use bed nets, while frequent attacks from malaria was [...] compromise its effectiveness and supposedly increase of malaria...
Multiple insecticide resistance in <em>Anopheles gambiae</em> from Tanzania: a major concern for malaria vector control (Publications)
development of insecticide resistance in the major malaria vectors. This study was carried out to monitor the susceptibility status of major malaria vectors to insecticides used for IRS and LLINs in mainland [...] BACKGROUND: Malaria vector control in Tanzania is based on use of long-lasting insecticide treated nets (LLINs) and indoor residual spraying (IRS), which both rely on the use of chemical insecticides. [...] An. gambiae sensu stricto (s.s.) Kisumu strain. RESULTS: Anopheles arabiensis...
Global investment targets for malaria control and elimination between 2016 and 2030 (Publications)
Background: Access to malaria control interventions falls short of universal health coverage. The Global Technical Strategy for malaria targets at least 90% reduction in case incidence and mortality rates [...] to reach these targets will be determined in part by investments in malaria. This study estimates the financing required for malaria control and elimination over the 2016-2030 period. Methods: A mathematical [...] coverage on burden and costs. The cost analysis took a public provider...
Sustained malaria control over an 8-year period in Papua New Guinea: the challenge of low-density asymptomatic <em>Plasmodium</em> infections (Publications)
Background: The scale-up of effective malaria control in the last decade has resulted in a substantial decline in the incidence of clinical malaria in many countries. The effects on the proportions of [...] has resulted in reduced malaria transmission potential, but an increasing proportion of gametocyte carriers are asymptomatic and submicroscopic and represent a challenge to malaria control.
malERA: an updated research agenda for combination interventions and modelling in malaria elimination and eradication (Publications)
number of countries embarking on malaria elimination programmes, national and local decisions to select combinations of tools and deployment strategies directed at malaria elimination must address rapidly [...] This paper summarises key advances and priorities since the 2011 presentation of the Malaria Eradication Research Agenda (malERA), with a focus on the combinations of intervention tools and strategies [...] deployment against a heterogeneous transmission background is a challenge.
