Mapping the endemicity and seasonality of clinical malaria for intervention targeting in Haiti using routine case data (Publications)
Towards the goal of malaria elimination on Hispaniola, the National Malaria Control Program of Haiti and its international partner organisations are conducting a campaign of interventions targeted to high-risk
A stable, oligosymptomatic malaria focus in Thailand (Publications)
residents of a non-migratory farming village in south-eastern Thailand was visually examined for malaria parasites monthly for 2 years. Nearly 97% of the population had at least one (median = 5) patent [...] negative. The spleen rate (89% stage 1) was 24% in those under 15 years old and 7% in those older. No malaria mortality was seen P. falciparum cases treated for 10 d with quinine+tetracycline (QT) cleared the [...] better with MSP than with QT. The role played by hyperendemic, cryptic foci...

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.
