Real-time dispersal of malaria vectors in rural Africa monitored with lidar (Publications)
observation of mosquito behavior with high spatio-temporal resolution limits progress towards improved malaria vector control. We deployed a high-resolution entomological lidar to monitor a half-kilometer static [...] this study demonstrate how lidar-based monitoring could dramatically improve our understanding of malaria vector ecology and control options.
Variability in white blood cell count during uncomplicated malaria and implications for parasite density estimation: a WorldWide Antimalarial... (Publications)
count during acute uncomplicated malaria, and estimate the impact of using an assumed value of WBC on estimates of parasite density and clearance. METHODS: Uncomplicated malaria drug efficacy studies that measured [...] and vivax (n = 2678) malaria, respectively. At presentation, higher WBC counts were seen among patients with higher parasitaemia, severe anaemia and, for individuals with vivax malaria, in regions with shorter [...] reference. RESULTS: Eighty-four studies enrolling 27,656...
Malaria, climate variability, and interventions: modelling transmission dynamics (Publications)
of the relative impact of climate change on malaria dynamics is a complex problem. Climate is a well-known factor that plays a crucial role in driving malaria outbreaks in epidemic transmission areas. However [...] influence in endemic environments with intensive malaria control interventions is not fully understood, mainly due to the scarcity of high-quality, long-term malaria data. The demographic surveillance systems [...] effects of weather variability on the burden of malaria. Here, using a...
Modelling the impact of interventions on imported, introduced and indigenous malaria infections in Zanzibar, Tanzania (Publications)
Malaria cases can be classified as imported, introduced or indigenous cases. The World Health Organization's definition of malaria elimination requires an area to demonstrate that no new indigenous cases [...] cases have occurred in the last three years. Here, we present a stochastic metapopulation model of malaria transmission that distinguishes between imported, introduced and indigenous cases, and can be used [...] interventions in a setting with low transmission and ongoing case importation....
Acceptability, feasibility, drug safety, and effectiveness of a pilot mass drug administration with a single round of sulfadoxine-pyrimethamine plus... (Publications)
For a malaria elimination strategy, Haiti's National Malaria Control Program piloted a mass drug administration (MDA) with indoor residual spraying (IRS) in 12 high-transmission areas across five communes [...] round of MDA/IRS on malaria transmission was not found using a standard pre- and post-intervention comparison, it is possible there was blunting of the peak transmission. Seasonal malaria transmission patterns
Geo-epidemiology of malaria incidence in the Vhembe District to guide targeted elimination strategies, South-Africa, 2015-2018: a local resurgence (Publications)
to classify the 474 smoothed malaria incidence curves. Thereafter, validity indices were used to determine the number of malaria incidence patterns. The cumulative malaria incidence of the study area was [...] Findings show also unusual malaria phenomena in Vhembe District that hinder malaria elimination in South Africa. Assessing the factors associated with these unusual malaria phenome would be helpful on [...] results. Therefore, in the process of refining local malaria control and...
Bridging the gap from molecular surveillance to programmatic decisions for malaria control and elimination (Publications)
An increasing number of molecular and genomic assays are available to study malaria parasite populations. However, so far they have played a marginal role in informing policy and programmatic decision-making [...] the origin of imported infections and characterize transmission chains in settings with very low malaria transmission, and using serology to monitor recent and past exposures in low-transmission settings [...] integrate molecular and genomic data into control program decision-making,...
