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...
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...
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
Strengthening surveillance systems for malaria elimination by integrating molecular and genomic data (Publications)
elimination efforts are currently going on with the objective of reducing malaria morbidity and mortality by 90% and malaria elimination in at least 35 countries by 2030. Strengthening surveillance systems [...] Unprecedented efforts in malaria control over the last 15 years have led to a substantial decrease in both morbidity and mortality in most endemic settings. However, these progresses have stalled over [...] such as polymerase chain reaction (PCR) and quantitative PCR (qPCR) are...
Eave ribbons treated with transfluthrin can protect both users and non-users against malaria vectors (Publications)
treated with spatial repellents effectively prevent human exposure to outdoor-biting and indoor-biting malaria mosquitoes, and could constitute a scalable and low-cost supplement to current interventions, such [...] ribbons alone. CONCLUSION: Transfluthrin-treated eave ribbons protect both users and non-users against malaria mosquitoes indoors and outdoors. The mosquito-killing property of transfluthrin can magnify the communal
Multiplicity of asymptomatic <em>Plasmodium falciparum </em>infections and risk of clinical malaria: a systematic review and pooled analysis of... (Publications)
subsequent febrile malaria or with an increased risk. CONCLUSIONS: The number of clones in asymptomatic P. falciparum infections is associated with different risks of subsequent clinical malaria depending on [...] BACKGROUND: The malaria parasite Plasmodium falciparum holds an extensive genetic polymorphism. In this pooled analysis, we investigate how the multiplicity, i.e. the number of co-infecting clones, in [...] in asymptomatic P. falciparum infections affects the subsequent risk of...
Mass campaigns combining antimalarial drugs and anti-infective vaccines as seasonal interventions for malaria control, elimination and prevention of... (Publications)
of existing malaria interventions is becoming increasingly important as evidence mounts that progress on reducing malaria incidence is stalling and threatened by resistance. METHODS: Malaria transmission [...] on and intervention dynamics were simulated using OpenMalaria, an individual-based simulation model of malaria transmission, by considering a seasonal transmission setting and by varying epidemiological [...] of seasonal mass applications of preventative anti-infective malaria vaccines,...
