Vector composition, abundance, biting patterns and malaria transmission intensity in Madang, Papua New Guinea: assessment after 7 years of an... (Publications)
BACKGROUND: A malaria control programme based on distribution of long-lasting insecticidal bed nets (LLINs) and artemisinin combination therapy began in Papua New Guinea in 2009. After implementation of [...] of the programme, substantial reductions in vector abundance and malaria transmission intensity occurred. The research reported here investigated whether these reductions remained after seven years of [...] Anopheles per screen-night and 2.2-31.1 Anopheles per person-night), and spatially...
Patterns of human exposure to malaria vectors in Zanzibar and implications for malaria elimination efforts (Publications)
study for malaria elimination. The islands have experienced a dramatic reduction in malaria burden since the introduction of effective vector control interventions and case management. Malaria prevalence [...] sleep. Supplemental interventions targeting outdoor exposure to malaria vectors, and groups that may be at increased risk of exposure to malaria vectors, should be explored. [...] for elimination. METHODS: To better understand factors that may contribute to remaining low-level malaria...
Child health and infection with low density (CHILD) malaria: a protocol for a randomised controlled trial to assess the long-term health and... (Publications)
participants receive malaria testing using RDT and qPCR three times annually, and malaria testing by RDT only when presenting with fever. PCDm and PCD participants receive malaria testing by RDT and qPCR [...] INTRODUCTION: As malaria declines, low-density malaria infections (LMIs) represent an increasing proportion of infections and may have negative impacts on child health and cognition, necessitating development [...] respectively, when presenting with fever. RDT or qPCR positive...
Fake malaria and hidden parasites - the ambiguity of malaria (Publications)
and education, programmes, and as a result, biomedical knowledge on malaria is comparatively high. However the cultural model of malaria does not always explain all the events that occur during an actual [...] Lay perspectives and health-seeking behaviour for malaria were investigated in an ethnographic study carried out in a village in south-eastern Tanzania. The inhabitants have easy access to hospital services [...] or the symptoms persist despite antimalarial treatment. Under these...
Dihydroartemisinin-piperaquine effectiveness for seasonal malaria chemoprevention in settings with extended seasonal malaria transmission in Tanzania (Publications)
course of DP for three consecutive months regardless of malaria infection status, and those in the control clusters received no intervention. Malaria infection was assessed at before the first-round and at [...] Effectiveness of dihydroartemisinin-piperaquine (DP) as seasonal malaria chemoprevention (SMC) was assessed in Nanyumbu and Masasi Districts. Between March and June 2021, children aged 3-59 months were [...] at 7 weeks after the third-round of DP in both arms. Malaria prevalence after...
Implementation research of a cluster randomized trial evaluating the implementation and effectiveness of intermittent preventive treatment for malaria... (Publications)
since the malaria epidemiologic shift to school-aged children was noted. In the meantime, school-aged children (5-15 years) have become increasingly more vulnerable with asymptomatic malaria prevalence [...] to 70%, making them reservoirs for subsequent transmission of malaria in the endemic communities. Intermittent Preventive Treatment of malaria in schoolchildren (IPTsc) has proven to be an effective tool [...] Tanzania so as to understand the operational feasibility and effectiveness of...
Geostatistical modelling of malaria indicator survey data to assess the effects of interventions on the geographical distribution of malaria... (Publications)
BACKGROUND: Malaria burden in Uganda has declined disproportionately among regions despite overall high intervention coverage across all regions. The Uganda Malaria Indicator Survey (MIS) 2014-15 was the [...] intervention effects on malaria prevalence in Uganda among children less than 5 years, assess intervention effects at regional level, and estimate geographical distribution of malaria prevalence in the country [...] on malaria prevalence at national and regional levels.

and the Plasmodium lactate dehydrogenase (pLDH) to microscopy (thick smears) for the diagnosis of malaria. PCR was used to determine whether deletions of the histidine-rich central repeat region of the hrp2 [...] CONCLUSION: This prospective study of RDT performance coincided with a decline in the intensity of malaria transmission in Kibirizi (fall in slide positivity from 46 to 3%). This decline was associated with [...] could reduce the impact of false-negative HRP2-based RDTs for detection of...
