malERA: an updated research agenda for characterising the reservoir and measuring transmission in malaria elimination and eradication (Publications)
key advances in defining the infectious reservoir for malaria and the measurement of transmission for research and programmatic use since the Malaria Eradication Research Agenda (malERA) publication in 2011 [...] is variable. New and improved measures of transmission need to be operationally feasible for the malaria programmes. Outputs from these research priorities should allow the development of a set of approaches

effectiveness of interventions ('effectiveness decay'), and respond to dynamic and changing needs. The malaria eradication research agenda (malERA) Refresh consultative process for the Panel on Health Systems [...] Research identifies opportunities to build health systems evidence and the tools needed to eliminate malaria from different zones, countries, and regions and to eradicate it globally. The research questions [...] include delivery strategies to meet the changing dynamics of needs of...
Infant and child mortality in relation to malaria transmission in KEMRI/CDC HDSS, Western Kenya: validation of verbal autopsy (Publications)
(VA) is widely used for estimating malaria specific mortality rates, but does not reliably distinguish malaria from other febrile illnesses. Overall malaria attributable mortality includes both direct and [...] both all-cause and malaria-specific mortality. 48.2% of the deaths could be attributed to malaria by analysing the exposure-response relationship, though only 20.5% of VAs assigned malaria as the cause and [...] BACKGROUND: Malaria transmission reduction is a goal of many malaria control...
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)

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...
Longitudinal estimation of <em>Plasmodium falciparum </em>prevalence in relation to malaria prevention measures in six sub-Saharan African countries (Publications)
(PfPR) is a widely used metric for assessing malaria transmission intensity. This study was carried out concurrently with the RTS,S/AS01 candidate malaria vaccine Phase III trial and estimated PfPR over [...] 3 sites. Surveys were usually performed during the peak malaria parasite transmission season, in one home visit, when medical history and malaria risk factors/prevention measures were collected, and a blood [...] 0.52, 0.68, 0.41) and bed net use in 2 surveys (ORs: 0.63, 0.68, 1.03, 1.78)...
Lysophosphatidylcholine regulates sexual stage differentiation in the human malaria parasite <em>Plasmodium falciparum</em> (Publications)
bottleneck in the Plasmodium life cycle and a key intervention target of ongoing efforts to eradicate malaria. Sexual differentiation is essential for this process, as only sexual parasites, called gametocytes [...] activation of sexual-stage-specific transcription and gametocyte formation. Our results reveal that malaria parasites can sense and process host-derived physiological signals to regulate differentiation. These [...] of the sexual differentiation pathway in Plasmodium that may provide...
Mapping multiple components of malaria risk for improved targeting of elimination interventions (Publications)

Implementing tailored [...] There is a long history of considering the constituent components of malaria risk and the malaria transmission cycle via the use of mathematical models, yet strategic planning in endemic countries tends [...] tends not to take full advantage of available disease intelligence to tailor...
