Indigenous <em>Plasmodium malariae</em> infection in an endemic population at the Thai-Myanmar border (Publications)
Plasmodium malariae is a neglected malaria parasite. It has wide geographic distribution and, although often associated with mild malaria, is linked to a high burden of anemia and nephrotic syndromes. [...] 2013-June 2014 in which P. malariae infection was detected. Of the 812 study participants, two were found to be infected with P. malariae. One had an infection that led to acute malaria, but the other was positive [...] positive for P. malariae at multiple visits during the study and...
Global fund financing to the 34 malaria-eliminating countries under the new funding model 2014-2017: an analysis of national allocations and regional... (Publications)
BACKGROUND: The Global Fund to Fight AIDS, Tuberculosis, and Malaria (GFATM) has been the largest financial supporter of malaria since 2002. In 2011, the GFATM transitioned to a new funding model (NFM) [...] NFM to the 34 malaria-eliminating countries. METHODS: Average annual disbursements under the old funding model were compared to average annual national allocations for all eligible 34 malaria-eliminating [...] funding declines for malaria investments in low transmission countries, the GFATM...
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...
RTS,S malaria vaccine pilot studies: addressing the human realities in large-scale clinical trials (Publications)
A malaria vaccine as part of the integrated malaria control and elimination efforts will have a major impact on public health in sub-Sahara Africa. The first malaria vaccine, RTS,S, now enters pilot i [...] the malaria vaccine clinical trial experiences, key ethical practices for effective clinical trial research in low-resource settings are described. For successful vaccine integration into malaria intervention
Linking human behaviours and malaria vector biting risk in south-eastern Tanzania (Publications)
To accelerate malaria elimination in areas where core interventions such as insecticide-treated nets (ITNs) are already widely used, it is crucial to consider additional factors associated with persistent [...] persistent transmission. Qualitative data on human behaviours and perceptions regarding malaria risk was triangulated with quantitative data on Anopheles mosquito bites occurring indoors and outdoors in sou [...] south-eastern Tanzania communities where ITNS are already used but lower...
Human behaviour and residual malaria transmission in Zanzibar: findings from in-depth interviews and direct observation of community events (Publications)
risk of malaria infection during these times. Travel and migration emerged as a crucial issue and participants viewed seasonal workers coming from mainland Tanzania as more likely to have a malaria infection [...] CONCLUSIONS: Targeting malaria interventions effectively is critical and should be informed by a clear understanding of relevant human behaviour. These findings highlight malaria prevention gaps in Zanzibar [...] final phases of malaria elimination. Development and deployment of...
Modelling the relationship between malaria prevalence as a measure of transmission and mortality across age groups (Publications)
prevalence has been used widely as a measure of malaria transmission, especially in malaria endemic areas. However, its contribution and relationship to malaria mortality across different age groups has not [...] all-cause and malaria-specific mortality. CONCLUSION: Malaria parasitaemia from cross-sectional surveys was associated with mortality across age groups over 4 to 5 year periods with clinical malaria more strongly [...] surveys from the Kisumu HDSS between 2007 and 2015 were used to...
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...
