Mass distribution of free insecticide-treated nets do not interfere with continuous net distribution in Tanzania (Publications)
BACKGROUND: To protect the most vulnerable groups from malaria (pregnant women and infants) the Tanzanian Government introduced a subsidy (voucher) scheme in 2004, on the basis of a public-private partnership [...] for the continuation of this effort in Tanzania and for emulation by other countries with endemic malaria
<em>Plasmodium vivax</em> populations are more genetically diverse and less structured than sympatric <em>Plasmodium falciparum</em> populations (Publications)
INTRODUCTION: The human malaria parasite, Plasmodium vivax, is proving more difficult to control and eliminate than Plasmodium falciparum in areas of co-transmission. Comparisons of the genetic structure [...] may provide insight into the mechanisms underlying the resilience of P. vivax and can help guide malaria control programs. METHODOLOGY/PRINCIPLE FINDINGS: P. vivax isolates representing the parasite populations
Ownership and usage of mosquito nets after four years of large-scale free distribution in Papua New Guinea (Publications)
Guinea (PNG) is a highly malaria endemic country in the South-West Pacific with a population of approximately 6.6 million (2009). In 2004, the country intensified its malaria control activities with support
Elimination of <em>Schistosoma mansoni</em> in infected mice by slow release of artemisone (Publications)
anti-plasmodial activity, and reduced toxicity compared to other artemisinins in clinical use against malaria. We infected adult mice by subcutaneous injection of S. mansoni cercariae (about 200) and treated [...] release of the artemisone that was verified in vivo and in vitro bioassays using drug-sensitive malaria parasites. We found superior strong anti-schistosome effects up to a total reduction of worm number
First detection of N1575Y mutation in pyrethroid resistant <em>Anopheles gambiae</em> in Southern Côte d'Ivoire (Publications)
insecticide classes is widespread. In an agricultural area of Southern Cote d'Ivoire, the main malaria vector Anopheles coluzzii shows multiple resistance across insecticides mediated by both target site [...] mutation in Cote d'Ivoire, and as in other populations, it is found in both dominant West African malaria vector species. Continued monitoring of N1575Y is underway, as are studies to elucidate its contribution
Very high carriage of gametocytes in asymptomatic low-density <em>Plasmodium falciparum</em> and <em>P. vivax</em> infections in western Thailand (Publications)
Plasmodium spp. are common in low endemicity areas worldwide, but outside Africa, their contribution to malaria transmission is poorly understood. Community-based studies with highly sensitive molecular diagnostics [...] gametocytes indicates that these infections may contribute substantially to the maintenance of local malaria transmission.
Multiplicity of <em>Plasmodium falciparum</em> infection following intermittent preventive treatment in infants (Publications)
Intermittent preventive treatment in infants with sulphadoxine-pyrimethamine (IPTi-SP) reduces malaria morbidity by 20% to 33%. Potentially, however, this intervention may compromise the acquisition of [...] of polyclonal infections (69.6% vs. 69.7%; P = 0.99). Adjusting for study site, current and prior malaria, parasite density, and season did not change this finding. CONCLUSIONS: IPTi-SP appears to have no
A 10 year study of the cause of death in children under 15 years in Manhica, Mozambique (Publications)
diseases accounted for 9.5% of the defined causes of death, and injuries for 3.9% of causes of deaths. Malaria was the single largest cause, accounting for 21.8% of cases. Pneumonia with 9.8% was the second leading [...] area. The pattern of childhood mortality in Manhica area is typical of developing countries where malaria, pneumonia and HIV/AIDS are important causes of death
