Virosome-formulated <em>Plasmodium falciparum</em> AMA-1 & CSP derived peptides as malaria vaccine: randomized phase 1b trial in semi-immune... (Publications)
evaluate the safety and immunogenicity of two virosome formulated malaria peptidomimetics derived from Plasmodium falciparum AMA-1 and CSP in malaria semi-immune adults and children. METHODS: The design was a [...] age-deescalating study with two immunizations. 10 adults and 40 children (aged 5-9 years) living in a malaria endemic area were immunized with PEV3B or virosomal influenza vaccine Inflexal(R)V on day 0 and 90 [...] from 4 to 66 in children. As an exploratory outcome, we found that the...
Selection of mosquito life-histories: a hidden weapon against malaria? (Publications)
BACKGROUND: There has recently been a substantial decline in malaria incidence in much of Africa. While the decline can clearly be linked to increasing coverage of mosquito vector control interventions [...] be driving selection for a shift in mosquito life history that reduces their ability to transmit malaria parasites. Specifically it is hypothesized that by substantially increasing the extrinsic rate of [...] their resources towards greater short-term reproduction at the expense of...
Willingness to use a rapid diagnostic test for malaria in a rural area of central Côte d'Ivoire (Publications)
elimination of malaria, particularly in areas where health services are deficient. The aim of this study was to determine knowledge, attitudes, practices and beliefs in relation to RDTs for malaria in rural [...] in Bozi and were offered an RDT for malaria were interviewed in April 2010 using a pre-tested questionnaire on practice and perceptions in relation to RDTs for malaria. The relationships between acceptance [...] an RDT. The concurrent availability and use of RDTs for HIV and malaria was...
Cost-sharing strategies combining targeted public subsidies with private-sector delivery achieve high bednet coverage and reduced malaria transmission... (Publications)
insecticide-treated nets (ITNs) for malaria prevention in the Kilombero Valley, southern Tanzania, since 1996. Here we evaluate resulting changes in bednet coverage and malaria transmission. METHODS: Bednets [...] but now-obsolete technologies available at the time resulted in low insecticide treatment rates. Malaria transmission remained intense but was substantially reduced: Compared with an exceptionally high
The usefulness of twenty-four molecular markers in predicting treatment outcome with combination therapy of amodiaquine plus... (Publications)
plus sulphadoxine-pyrimethamine (SP) was introduced as first-line treatment against uncomplicated malaria in 2000. METHODS: We assessed in vivo treatment failure rates with AQ+SP in two different areas in
Preventing childhood malaria in Africa by protecting adults from mosquitoes with insecticide-treated nets (Publications)
BACKGROUND: Malaria prevention in Africa merits particular attention as the world strives toward a better life for the poorest. Insecticide-treated nets (ITNs) represent a practical means to prevent malaria in [...] targets for ITN coverage beyond vulnerable groups. METHODS AND FINDINGS: Using field-parameterized malaria transmission models, we show that high (80% use) but exclusively targeted coverage of young children
Quantifying behavioural interactions between humans and mosquitoes: Evaluating the protective efficacy of insecticidal nets against malaria... (Publications)
ABSTRACT: BACKGROUND: African malaria vectors bite predominantly indoors at night so sleeping under an Insecticide-Treated Net (ITN) can greatly reduce malaria risk. Behavioural adaptation by mosquitoes [...] allow vector mosquitoes to bite outside of peak sleeping hours and undermine efficacy of this key malaria prevention measure. METHODS: High coverage with largely untreated nets has been achieved in the Kilombero [...] peak sleeping hours, respectively. ITNs consistently conferred > 70%...
Spatio-temporal analysis of the role of climate in inter-annual variation of malaria incidence in Zimbabwe (Publications)
inter-annual variation in malaria incidence. Quantitative description of the space-time effect of this association has practical implications for the development of operational malaria early warning system [...] system (MEWS) and malaria control. We used Bayesian negative binomial models for spatio-temporal analysis of the relationship between annual malaria incidence and selected climatic covariates at a district level [...] 1988-1999. RESULTS: Considerable inter-annual variations were observed...
Effectiveness of combined intermittent preventive treatment for children and timely home treatment for malaria control (Publications)
awaiting for the arrival of an effective and affordable malaria vaccine, there is a need to make use of the available control tools to reduce malaria risk, especially in children under five years and pregnant [...] important component of the malaria control strategy. This study explored the potential of a strategy of intermittent preventive treatment for children (IPTC) and timely treatment of malaria-related febrile illness [...] of febrile malaria illness, impacts significantly on the parasite...
