Epidemiological links between malaria parasitaemia and hypertension: findings from a population-based survey in rural Côte d'Ivoire (Publications)
between malaria parasitaemia and hypertension in Ivorian adults. METHODS: We estimated the adjusted odds ratios (OR) and 95% confidence intervals (CI) of hypertension in relation to malaria parasitaemia [...] mmHg or clinician-diagnosed hypertension. RESULTS: Prevalence of malaria parasitaemia and hypertension were 10 and 22%, respectively. Malaria parasitaemia was negatively associated with hypertension in p [...] Participants having microscopic malaria parasitaemia with elevated body...
Immuno-gold silver staining assays on capillary-driven microfluidics for the detection of malaria antigens (Publications)
a lack of highly sensitive malaria RDTs that can detect low antigen concentration at the onset of infection. Here, we present a strategy to improve the sensitivity of malaria RDTs by using capillary-driven [...] al to the concentration of antigen in a sample. We illustrate this method using the recombinant malaria antigen Plasmodium falciparum histidine-rich-protein 2 (rPfHRP2) spiked in human serum. This antigen [...] min, which is approaching the desired sensitivity needed in the Target...
Spatial-temporal heterogeneity in malaria receptivity is best estimated by vector biting rates in areas nearing elimination (Publications)
when vector control can be withdrawn after malaria is eliminated depend on the receptivity or potential of an area to support vector populations. To guide malaria control and elimination programmes, the potential [...] estimate malaria receptivity and transmission were compared within and among geographically localised villages of active transmission in the Western Province of the Solomon Islands. RESULTS: Malaria transmission [...] inoculation and parity rates could not be measured with the...
Diagnostic performance of conventional and ultrasensitive rapid diagnostic tests for malaria in febrile outpatients in Tanzania (Publications)
Background: A novel ultra-sensitive malaria RDT (us-RDT) has been developed for improved active P.falciparum case detection. The utility of this us-RDT in clinical diagnosis and fever management has not [...] infections. Conclusion: There is neither gain nor risk to apply us-RDT rather than co-RDT for clinical malaria diagnosis. In febrile patients, only a small proportion of infections are characterized by parasite
Nationwide school malaria parasitaemia survey in public primary schools, the United Republic of Tanzania (Publications)
school, malaria survey was implemented to assess the risk factors of malaria prevalence and bed net use among primary school children in mainland Tanzania. This allowed the mapping of malaria prevalence [...] for malaria infection and for bed net use while adjusting for school effect. RESULTS: In total, 49,113 children were interviewed and tested for malaria infection. The overall prevalence of malaria was [...] prevalence at council level and assessment of malaria risk factors among school...
Inter-sectoral approaches for the prevention and control of malaria among the mobile and migrant populations: a scoping review (Publications)
knowledge about malaria, initiation and promotion of bed nets utilization, increased access to diagnosis and treatment in a surveillance context and contributed towards a reduction in malaria transmission [...] with correct knowledge about malaria transmission (70%, 95% CI 57-83%). Interventions targeting the use of bed nets utilization were two times more likely to reduce malaria incidence amongst the targeted [...] BACKGROUND: Malaria cases among mobile and migrant populations (MMPs) represent...
The potential of pregnant women as a sentinel population for malaria surveillance (Publications)
Monthly ANC malaria test-positivity data from all Tanzanian health facilities for January 2014 to May 2016 was compared to prevalence data from the School Malaria Parasitaemia Survey 2015, the Malaria Indicator [...] proposed as a pragmatic sentinel population for malaria surveillance. However, the representativeness of routine ANC malaria test-positivity and its relationship with prevalence in other population subgroups [...] Indicator Survey (MIS) 2015/16, the Malaria Atlas Project 2015, and a...
Increase of dose associated with decrease in protection against controlled human malaria infection by PfSPZ vaccine in Tanzanian adults (Publications)

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
Resurgence of malaria infection after mass treatment: a simulation study (Publications)

Individual-based stochastic models of malaria transmission (OpenMalaria) were then used to estimate the probability and likely rates of resurgence in realistic [...] if mass drug administration (MDA) might shorten the time to elimination of Plasmodium falciparum malaria, when vector control measures and reactive surveillance strategies are scaled-up. A concern with [...] of bistability. Importation rates are important only when this threshold is very...
