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. Further...
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
malERA: an updated research agenda for health systems and policy research in malaria elimination and eradication (Publications)
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...
RTS,S malaria vaccine pilot studies: addressing the human realities in large-scale clinical trials (Publications)
A malaria vaccine as part of the integrated malaria control and elimination efforts will have a major impact on public health in sub-Sahara Africa. The first malaria vaccine, RTS,S, now enters pilot i [...] the malaria vaccine clinical trial experiences, key ethical practices for effective clinical trial research in low-resource settings are described. For successful vaccine integration into malaria intervention
Linking human behaviours and malaria vector biting risk in south-eastern Tanzania (Publications)
To accelerate malaria elimination in areas where core interventions such as insecticide-treated nets (ITNs) are already widely used, it is crucial to consider additional factors associated with persistent [...] persistent transmission. Qualitative data on human behaviours and perceptions regarding malaria risk was triangulated with quantitative data on Anopheles mosquito bites occurring indoors and outdoors in sou [...] south-eastern Tanzania communities where ITNS are already used but lower...
Human behaviour and residual malaria transmission in Zanzibar: findings from in-depth interviews and direct observation of community events (Publications)
risk of malaria infection during these times. Travel and migration emerged as a crucial issue and participants viewed seasonal workers coming from mainland Tanzania as more likely to have a malaria infection [...] CONCLUSIONS: Targeting malaria interventions effectively is critical and should be informed by a clear understanding of relevant human behaviour. These findings highlight malaria prevention gaps in Zanzibar [...] final phases of malaria elimination. Development and deployment of...
Modelling the relationship between malaria prevalence as a measure of transmission and mortality across age groups (Publications)
prevalence has been used widely as a measure of malaria transmission, especially in malaria endemic areas. However, its contribution and relationship to malaria mortality across different age groups has not [...] all-cause and malaria-specific mortality. CONCLUSION: Malaria parasitaemia from cross-sectional surveys was associated with mortality across age groups over 4 to 5 year periods with clinical malaria more strongly [...] surveys from the Kisumu HDSS between 2007 and 2015 were used to...
Modelling reactive case detection strategies for interrupting transmission of <em>Plasmodium falciparum</em> malaria (Publications)
BACKGROUND: As areas move closer to malaria elimination, a combination of limited resources and increasing heterogeneity in case distribution and transmission favour a shift to targeted reactive interventions [...] strategies vary, and it is unclear which are most effective in achieving elimination. METHODS: OpenMalaria, an established individual-based stochastic model, was used to simulate RCD in a Zambia-like setting
