treatment and control of malaria, particularly within artemisinin-based combination therapies. Since the artemisinins also exhibit antischistosomal properties, their use in areas where malaria and schistosomiasis [...] in areas where malaria and schistosomiasis co-exist and where artemisinin-based combination therapies are introduced, since artemisinin-based combination therapies as part of a malaria control package
Molecular epidemiology and seroprevalence in asymptomatic <em>Plasmodium falciparum</em> infections of Malagasy pregnant women in the highlands (Publications)
BACKGROUND: Malaria epidemiology in Madagascar is classified into four different areas, ranging from unstable seasonal transmission in the highlands to hyperendemic perennial transmission areas in the [...] the costal level. Most malaria studies in Madagascar are focused on symptomatic children. However, because of the low transmission in some areas with correspondingly low level of semi-immunity, adults are [...] genetic epidemiology of malarial infections in pregnant women in order to provide...
Following in Soper's footsteps: northeast Brazil 63 years after eradication of <em>Anopheles gambiae</em> (Publications)
years ago was a new and horrifying experience. This African mosquito is an exceptionally effective malaria vector because it is well adapted to feeding upon people and to exploiting aquatic habitats associated [...] with our daily activities. Anopheles gambiae sensu lato probably accounts for most of the world's malaria deaths and socioeconomic burden. Fortunately, the Brazilian experience had a happy ending. The prospect [...] aegypti elimination, the Rockefeller Foundation and Brazilian...
Amino acid dimorphism and parasite immune evasion: cellular immune responses to a promiscuous epitope of<em> Plasmodium falciparum</em> merozoite... (Publications)
suitability as component of a multi-epitope malaria vaccine. We have analyzed the CD4 T cell responses in a group of human volunteers immunized with a synthetic malaria peptide vaccine containing a single MSP-143-53 [...] Like most other surface-exposed antigens of Plasmodium falciparum, the leading malaria vaccine candidate merozoite surface protein (MSP)-1 contains a large number of dimorphic amino acid positions. This [...] diversity is presumed to be associated with parasite immune evasion...
Analysis of <em>Plasmodium falciparum</em> var genes expressed in children from Papua New Guinea (Publications)
sequences was detected in symptomatic malaria, and a subgroup of frequently encountered var genes with complex head structure seems to be associated with severe malaria. A subset of var group C genes was [...] variable antigen P. falciparum erythrocyte membrane protein-1 (PfEMP1) is a major virulence factor in malaria. A large number of var genes encode PfEMP1, and we hypothesized that a restricted PfEMP1 repertoire [...] children. METHODS: var messenger RNA was isolated from 78 children with...
Costs and effects of the Tanzanian national voucher scheme for insecticide-treated nets (Publications)
approach in Tanzania has been to deliver a targeted subsidy for those most vulnerable to the effects of malaria while at the same time providing support to the development of the commercial ITN distribution system [...] system. In October 2004, with funds from the Global Fund to Fight AIDS Tuberculosis and Malaria, the government launched the Tanzania National Voucher Scheme (TNVS), a nationwide discounted voucher scheme [...] (and therefore nets delivered) and treated nets years. Estimates were...
Health information given by Swiss travel agencies (Publications)
agents mentioned preventive measures against malaria, but only 69% indicated the need for vaccinations against other diseases. Spontaneous advice on malaria risk and vaccinations was better than advice [...] through travel agencies every year. These agencies are thus an important source of information about malaria and other important health risks and little is known about the appropriate health information provided [...] advice given upon prompting. One fifth of all travel agents neither...
Indigenous emergence and spread of <em>kelch13</em> C469Y artemisinin-resistant <em>Plasmodium falciparum</em> in Uganda (Publications)
As part of the Community Access to Rectal Artesunate for Malaria project, we collected blood samples from 697 children with signs of severe malaria in northern Uganda between 2018 and 2020, before and after [...] Artemisinin-based combination therapies (ACTs) were introduced as the standard of care for uncomplicated malaria in Africa almost two decades ago. Recent studies in East Africa have reported a gradual increase [...] geographic origin of k13 mutations. Of the 697 children, 540 were...

The epidemiological models, implemented in OpenMalaria, were employed to study the impact of a single mass distribution of LLINs on malaria, both in terms of episodes prevented during the effective [...] BACKGROUND: The effectiveness of insecticide-treated nets in preventing malaria is threatened by developing resistance against pyrethroids. Little is known about how strongly this affects the effectiveness [...] levels of mortality in World Health Organization susceptibility tests,...
