The effect of antenna polarization and body morphology on the measurement uncertainty of a wearable multi-band distributed exposure meter
This paper studies the effect of antenna polarization on measurement uncertainty of a multi-band body-worn distributed exposure meter (BWDM). The BWDM is a device for assessing electromagnetic fields in real e...

Radiofrequency electromagnetic field exposure in everyday microenvironments in Europe: A systematic literature review
The impact of the introduction and advancement in communication technology in recent years on exposure level of the population is largely unknown. The main aim of this study is to systematically review literat...

Open AccessThe underlying reasons for very high levels of bed net use, and higher malaria infection prevalence among bed net users than non-users in the Tanzanian city of Dar es Salaam: a qualitative study
Bed nets reduce malaria-related illness and deaths, by forming a protective barrier around people slee** under them. When impregnated with long-lasting insecticide formulations they also repel or kill mosqui...

Open AccessInforming new or improved vector control tools for reducing the malaria burden in Tanzania: a qualitative exploration of perceptions of mosquitoes and methods for their control among the residents of Dar es Salaam
The effectiveness of malaria prevention with long-lasting insecticidal nets and indoor residual spraying is limited by emerging insecticide resistance, evasive mosquito behaviours that include outdoor biting, ...

Article
Open AccessThe epidemiology of residual Plasmodium falciparum malaria transmission and infection burden in an African city with high coverage of multiple vector control measures
In the Tanzanian city of Dar es Salaam, high coverage of long-lasting insecticidal nets (LLINs), larvicide application (LA) and mosquito-proofed housing, was complemented with improved access to artemisinin-ba...

Article
Open AccessSpatially aggregated clusters and scattered smaller loci of elevated malaria vector density and human infection prevalence in urban Dar es Salaam, Tanzania
Malaria transmission, primarily mediated by Anopheles gambiae, persists in Dar es Salaam (DSM) despite high coverage with bed nets, mosquito-proofed housing and larviciding. New or improved vector control strateg...

Open AccessMalaria vectors and their blood-meal sources in an area of high bed net ownership in the western Kenya highlands
Blood-meal sources of malaria vectors affect their capacity to transmit the disease. Most efficient malaria vectors prefer human hosts. However, with increasing personal protection measures it becomes more dif...

Open AccessMap** hotspots of malaria transmission from pre-existing hydrology, geology and geomorphology data in the pre-elimination context of Zanzibar, United Republic of Tanzania
Larval source management strategies can play an important role in malaria elimination programmes, especially for tackling outdoor biting species and for eliminating parasite and vector populations when they ar...

Open AccessLong-term trends in Anopheles gambiae insecticide resistance in Côte d’Ivoire
Malaria control is heavily dependent on the use of insecticides that target adult mosquito vectors via insecticide treated nets (ITNs) or indoor residual spraying (IRS). Four classes of insecticide are approve...

Article
Open AccessIncreasing role of Anopheles funestus and Anopheles arabiensis in malaria transmission in the Kilombero Valley, Tanzania
In order to sustain the gains achieved by current malaria control strategies, robust surveillance systems that monitor dynamics of vectors and their roles in malaria transmission over time are essential. This ...

Article
Open AccessEffective autodissemination of pyriproxyfen to breeding sites by the exophilic malaria vector Anopheles arabiensis in semi-field settings in Tanzania
Malaria vector control strategies that target adult female mosquitoes are challenged by the emergence of insecticide resistance and behavioural resilience. Conventional larviciding is restricted by high operat...

Article
Open AccessSterilising effects of pyriproxyfen on Anopheles arabiensis and its potential use in malaria control
Insecticide resistance poses a major threat to current vector control campaigns. Insecticides with novel modes of action are therefore in high demand. Pyriproxyfen (PPF), a conventional mosquito pupacide, has ...

Article
Open AccessA need for better housing to further reduce indoor malaria transmission in areas with high bed net coverage
The suppression of indoor malaria transmission requires additional interventions that complement the use of insecticide treated nets (ITNs) and indoor residual spraying (IRS). Previous studies have examined th...

Article
Open AccessAn affordable, quality-assured community-based system for high-resolution entomological surveillance of vector mosquitoes that reflects human malaria infection risk patterns
More sensitive and scalable entomological surveillance tools are required to monitor low levels of transmission that are increasingly common across the tropics, particularly where vector control has been succe...

Open AccessCommunity-owned resource persons for malaria vector control: enabling factors and challenges in an operational programme in Dar es Salaam, United Republic of Tanzania
Community participation in vector control and health services in general is of great interest to public health practitioners in develo** countries, but remains complex and poorly understood. The Urban Malari...

Open AccessA simple and efficient tool for trap** gravid Anopheles at breeding sites
No effective tool currently exists for trap** ovipositing malaria vectors. This creates a gap in our ability to investigate the behavior and ecology of gravid Anopheles.

Open AccessA tool box for operational mosquito larval control: preliminary results and early lessons from the Urban Malaria Control Programme in Dar es Salaam, Tanzania
As the population of Africa rapidly urbanizes, large populations could be protected from malaria by controlling aquatic stages of mosquitoes if cost-effective and scalable implementation systems can be designed.

Open AccessParticipatory map** of target areas to enable operational larval source management to suppress malaria vector mosquitoes in Dar es Salaam, Tanzania
Half of the population of Africa will soon live in towns and cities where it can be protected from malaria by controlling aquatic stages of mosquitoes. Rigorous but affordable and scaleable methods for map**...
