research portfolio as key elements for researching and applying evidence in malaria control and elimination as part of national malaria control programmes. [...] perspective. Its aim is to highlight the above-mentioned transformation by focusing on selected malaria research-cum-action interventions during the crucial period of the 1990s, which were tailored to
Knowledge of antimalarials and health seeking behaviour of households in case of suspected malaria in Democratic Republic of the Congo (Publications)
of the Congo (DRC) is heavily affected by malaria despite availability of effective treatments. Ignorance and unrecommended behaviour toward a suspected malaria case in households may contribute to this [...] urban Health Centres in each of the 11 previous provinces of DRC, all households with a case of malaria in the 15 days prior to the survey were selected. The patient or caregiver (responder) were interviewed [...] predictors of knowledge of recommended antimalarials and adequate behaviour...
Safety, immunogenicity and efficacy of PfSPZ vaccine against malaria in infants in western Kenya: a double-blind, randomized, placebo-controlled phase... (Publications)
infection in malaria-naive adults. Preclinical studies show that T cell-mediated immunity is required for protection and is readily induced in humans after vaccination. However, previous malaria exposure can [...] and vaccine efficacy (VE) in adults. We hypothesized that infants with less previous exposure to malaria would have improved immunity and protection. We conducted a multi-arm, randomized, double-blind, [...] tolerability, immunogenicity and efficacy of the PfSPZ Vaccine in infants in a...
Transfluthrin eave-positioned targeted insecticide (EPTI) reduces human landing rate (HLR) of pyrethroid resistant and susceptible malaria vectors in... (Publications)
of transfluthrin eave-positioned targeted insecticide (EPTI) depends on the resistance status of malaria vectors. METHODS: Ribbons treated with 5.25 g transfluthrin or untreated controls were used around
Analysis of contamination in cluster randomized trials of malaria interventions (Publications)
BACKGROUND: In cluster randomized trials (CRTs) of interventions against malaria, mosquito movement between households ultimately leads to contamination between intervention and control arms, unless they [...] which contamination measurably biases the estimate of effectiveness. A sigmoid function is fitted to malaria prevalence or incidence data as a function of the distance of households to the intervention boundary
Incidence of <em>Plasmodium falciparum</em> malaria infection in 6-month to 45-year-olds on selected areas of Bioko Island, Equatorial Guinea (Publications)
were 58 malaria infection episodes observed during the follow up period, including 47 first and 11 repeat infections. The incidence of malaria was 0.25 [95% CI (0.19, 0.32)] and of first malaria was 0.23 [...] study area, gender, malaria positivity at screening, and household socioeconomic status independently predicted the observed incidence of malaria. CONCLUSION: Despite intensive malaria control efforts on [...] BACKGROUND: Extensive malaria control measures have been implemented on Bioko...
Estimating intervention effectiveness in trials of malaria interventions with contamination (Publications)
Background In cluster randomized trials (CRTs) or stepped wedge cluster randomized trials (SWCRTs) of malaria interventions, mosquito movement leads to contamination between trial arms unless buffer zones separate [...] s are provided as a function of intervention coverage. The methods are applied to two SWCRTs of malaria interventions, the SolarMal trial on the impact of mass trapping of mosquitoes with odor-baited traps [...] effectiveness as a function of coverage. Conclusions The...
Unlocking the human factor to increase effectiveness and sustainability of malaria vector control (Publications)
decade in the fight against malaria there is a critical opportunity to elevate the role of social and behaviour change to increase the impact and sustainability of malaria control and elimination efforts [...] BACKGROUND: Progress in the fight against malaria has stalled in recent years, highlighting the importance of new interventions and tailored approaches. A critical factor that must be considered across [...] research with entomological and epidemiological evaluations will provide a more...
Early life adversity, biological adaptation, and human capital: evidence from an interrupted malaria control program in Zambia (Publications)
adaptation - immunity formation - for human capital accumulation. Using variation in early life malaria risk generated by an interrupted disease control program in Zambia, we show that exposure to infectious [...] infectious diseases during the first two years of life can reduce the harmful effects of malaria exposure on cognitive development during the preschool years. These findings suggest a non-linear and traj
