The relative contribution of climate variability and vector control coverage to changes in malaria parasite prevalence in Zambia 2006-2012 (Publications)
BACKGROUND: Four malaria indicator surveys (MIS) were conducted in Zambia between 2006 and 2012 to evaluate malaria control scale-up. Nationally, coverage of insecticide-treated nets (ITNs) and indoor [...] on malaria parasite prevalence over this period. METHODS: Nationally-representative MISs were conducted in April-June of 2006, 2008, 2010 and 2012 to collect household-level information on malaria control [...] between IRS and ITN coverage and climate variability and malaria parasite...
A need for better housing to further reduce indoor malaria transmission in areas with high bed net coverage (Publications)
: Despite significant reductions in vector density and malaria transmission caused by high coverage of ITNs, high numbers of host-seeking malaria vectors are still found indoors due to house designs that [...] BACKGROUND: The suppression of indoor malaria transmission requires additional interventions that complement the use of insecticide treated nets (ITNs) and indoor residual spraying (IRS). Previous studies [...] studies have examined the impact of house structure on malaria transmission in...
High prevalence of malaria in Zambezia, Mozambique: the protective effect of IRS versus increased risks due to pig-keeping and house construction (Publications)
high in many parts of the continent. This study investigated risk factors for malaria infection in children using three malaria indicator surveys from Zambezia province, Mozambique. The impact of IRS and [...] screened for malaria by rapid diagnostic tests. Caregiver interviews were used to assess household demographic and wealth characteristics and ITN and IRS coverage. Associations between malaria infection, [...] versus small households (1-4 persons). CONCLUSION: Malaria infection among...
Strategic roles for behaviour change communication in a changing malaria landscape (Publications)
quality strategic behaviour change communication (BCC) can improve malaria prevention and treatment behaviours. As progress is made towards malaria elimination, BCC becomes an even more important tool. BCC can [...] infections and their compliance with treatment, 3) to inform communities of the optimal timing of malaria control interventions, and 4) to explain changing diagnostic concerns (e.g. increasing false negatives [...] this commentary is to highlight the benefits and value for money that...
Impact of artemisinin-based combination therapy and insecticide-treated nets on malaria burden in Zanzibar (Publications)
The Roll Back Malaria strategy recommends a combination of interventions for malaria control. Zanzibar implemented artemisinin-based combination therapy (ACT) for uncomplicated malaria in late 2003 and [...] all malaria patients, while LLINs are distributed free to children under age 5 y ("under five") and pregnant women. We investigated temporal trends in Plasmodium falciparum prevalence and malaria-related [...] y) mortality decreased by 52%, 33%, and 71%, respectively. Similarly, malaria-rel...
Structure of the malaria vaccine candidate antigen CyRPA and its complex with a parasite invasion inhibitory antibody (Publications)
Invasion of erythrocytes by Plasmodial merozoites is a composite process involving the interplay of several proteins. Among them, the Plasmodium falciparum Cysteine-Rich Protective Antigen (PfCyRPA) i
Community-based surveillance to monitor mortality in a malaria-endemic and Ebola-epidemic setting in rural Guinea (Publications)
a reinforced malaria control program and one sous-prefecture without (Koundou) in Guinea. Deaths were recorded by key informants and classified as due to malaria or another cause. Malaria deaths were those [...] deaths were reported from July 2011-June 2014, of which 55.2% (N = 686) were reported as due to malaria. Malaria-attributable proportional mortality decreased by 26.5% (95% confidence interval [CI] = 13.9-33 [...] those reported as due to malaria or fever in the 3 days before death with...
