Nevertheless, an epidemiological study in 2012 demonstrated higher malaria prevalence among bed net users than non-users [...] against malaria. Houses with well-screened windows, with doors that shut properly, and that use insecticidal sprays against mosquitoes, were said not to use bed nets, while frequent attacks from malaria was [...] compromise its effectiveness and supposedly increase of malaria...
Sustained malaria control over an 8-year period in Papua New Guinea: the challenge of low-density asymptomatic <em>Plasmodium</em> infections (Publications)
Background: The scale-up of effective malaria control in the last decade has resulted in a substantial decline in the incidence of clinical malaria in many countries. The effects on the proportions of [...] has resulted in reduced malaria transmission potential, but an increasing proportion of gametocyte carriers are asymptomatic and submicroscopic and represent a challenge to malaria control.
PCR correction strategies for malaria drug trials: updates and clarifications (Publications)
Malaria drug trials conducted in endemic areas face a major challenge in their analysis because it is difficult to establish whether parasitaemia in blood samples collected after treatment indicate drug [...] public and private bodies who are working on the development, deployment, and surveillance of new malaria drugs. We aim to promote discussion around these issues and argue for the adoption of improved s
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,...
The <em>Plasmodium falciparum</em> Hsp70-x chaperone assists the heat stress response of the malaria parasite (Publications)
Plasmodium falciparum is the most lethal of human-infective malaria parasites. A hallmark of P. falciparum malaria is extensive remodeling of host erythrocytes by the parasite, which facilitates the d [...] Vakonakis, I. The Plasmodium falciparum Hsp70-x chaperone assists the heat stress response of the malaria parasite.
Repeated mosquito net distributions, improved treatment, and trends in malaria cases in sentinel health facilities in Papua New Guinea (Publications)
RESULTS: Malaria incidence initially ranged from 20 to 115/1000 population; subsequent trends varied by site. Overall, LLIN distributions had a cumulative effect, reducing the number of malaria cases with [...] not ACT, were associated with reductions of malaria cases in a range of settings, but sustainability of the gains appear to depend on local factors. Malaria programmes covering diverse transmission settings [...] al nets (LLIN), improved diagnosis and artemisinin-based combination therapy...
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...
