Operational coverage and timeliness of reactive case detection for malaria elimination in Zanzibar, Tanzania (Publications)
Since 2012, the Zanzibar Malaria Elimination Program has been implementing reactive case detection (RACD). Health facility (HF) staff send individual malaria case notifications by using mobile phones, [...] triggering a review of HF records and malaria testing and treatment at the household level by a district malaria surveillance officer. We assessed the completeness and timeliness of this system, from [...] Zanzibar achieved high operational coverage, timeliness was suboptimal. Patients...
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)
reducing malaria's impact. 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)
management, and test-and-treat interventions. 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...
The development and evaluation of a self-marking unit to estimate malaria vector survival and dispersal distance (Publications)
diseases such as malaria. Mosquito mark-release-recapture (MMRR) experiments are a popular method of measuring the survival and dispersal of disease vectors; however, examples with African malaria vectors are [...] This study demonstrates the successful use of a self-marking device in an MMRR study with African malaria vectors. This method may be useful in investigating population structure and dispersal of mosquitoes
Infected erythrocyte-derived extracellular vesicles alter vascular function via regulatory Ago2-miRNA complexes in malaria (Publications)
Malaria remains one of the greatest public health challenges worldwide, particularly in sub-Saharan Africa. The clinical outcome of individuals infected with Plasmodium falciparum parasites depends on [...] Altogether, these findings provide a mechanistic link between EVs and vascular dysfunction during malaria infection.
Sex: how malaria parasites get turned on (Publications)
initiation of this cell fate decision, ultimately providing the malaria community with a novel and important tool in the battle to prevent malaria transmission.
Malaria: «Einstein» und die Spritze der Hoffnung (Publications)
In Afrika läuft die weltweit erste Impfkampagne gegen Malaria. In Ghana, Malawi und Kenia werden bis 2022 gegen zwei Millionen Kleinkinder mit dem Vakzin «RTS’S» geimpft. «Einstein» hat die Entwicklung [...] begleitet. Die Langzeit-Dokumentation zeigt auf, wie schwierig der Weg zur ersehnten neuen Waffe gegen Malaria war. Die Schweiz spielte bei der Entwicklung des Impfstoffs eine tragende Rolle, doch die Testreihen [...] und echte Forschungspartnerschaft zwischen Nord und Süd möglich war. Die...
An interactive application for malaria elimination transmission and costing in the Asia-Pacific (Publications)
eliminate malaria in the region by 2030. The emergence and spread of artemisinin drug resistance in the Greater Mekong Subregion makes elimination urgent and strategic for the global goal of malaria eradication [...] regional, country and local settings, which means that different strategies are needed to eliminate malaria. However, models and their predictions can be seen as highly technical, limiting their use for decision [...] , we designed and developed an interactive application to...
