Increase of dose associated with decrease in protection against controlled human malaria infection by PfSPZ vaccine in Tanzanian adults (Publications)
reducing malaria's impact. PfSPZ Vaccine (radiation attenuated, aseptic, purified, cryopreserved Plasmodium falciparum [Pf] sporozoites [SPZ]) has been well tolerated and safe in > 1,526 malaria-naive and [...] (VE) of 5 doses of 2.7x105 PfSPZ of PfSPZ Vaccine was assessed in adults against controlled human malaria infection (CHMI) in the U.S. and Tanzania and intense field transmission of heterogeneous Pf in Mali
Malaria case management by community health workers in the Central African Republic from 2009-2014: overcoming challenges of access and instability... (Publications)
infectious diseases, including malaria. As a response, in 2008 an international non-governmental organization started a network of community health workers (CHWs) in the highly malaria-endemic region of northwest [...] hence different stages of conflict and unrest. Several indicators were measured over time, including malaria rapid diagnostic test (RDT) positivity rates, CHW reporting rates, and malnutrition indicators. RESULTS: [...] nearly 200,000 people who consulted a CHW during this period,...
The contribution of malaria control interventions on spatio-temporal changes of parasitaemia risk in Uganda during 2009-2014 (Publications)
BACKGROUND: In Uganda, malaria vector control interventions and case management with Artemisinin Combination Therapies (ACTs) have been scaled up over the last few years as a result of increased funding [...] children less than 5 years old and coverage of interventions was collected during the first two Malaria Indicator Surveys (MIS) conducted in 2009 and 2014, respectively. In this study, we quantify the [...] the North-East region to 100% in Kampala region. The estimated number of children...
Informing new or improved vector control tools for reducing the malaria burden in Tanzania: a qualitative exploration of perceptions of mosquitoes and... (Publications)
CONCLUSIONS: Outdoor transmission is widely accepted as an obstacle to malaria elimination. Larval source management, targeting both malaria vectors and nuisance-biting mosquitoes, is the preferred method for [...] BACKGROUND: The effectiveness of malaria prevention with long-lasting insecticidal nets and indoor residual spraying is limited by emerging insecticide resistance, evasive mosquito behaviours that include [...] to widespread environmental deterioration and lack of effective mosquito...

This study reports small-scale variations of i [...] villages across two seasons in Tanzania, where insecticidal bed nets are extensively used, but malaria transmission persists. Methods: WHO insecticide susceptibility assays were conducted on female and
State of inequality in malaria intervention coverage in sub-Saharan African countries (Publications)
BACKGROUND: Scale-up of malaria interventions over the last decade have yielded a significant reduction in malaria transmission and disease burden in sub-Saharan Africa. We estimated economic gradients [...] in coverage of malaria interventions and their distribution by wealth within and across countries. In most, economic gradients are lacking or favor the poorest for vector control; malaria services delivered [...] Using Demographic and Health Surveys we computed equity metrics to characterize...
