Travel to malaria-endemic areas: using digital geo-location to assess potential exposure risks and health behaviours (Publications)
and Tanzania, each presenting varying malaria risks. The extent to which travellers enter high-risk malaria-endemic areas in destinations with heterogeneous malaria risk remains unclear. We used geo-location [...] heterogeneous malaria risk (Brazil, India, Peru, Thailand), and (ii) compare mosquito bite prevention behaviours between these destinations and Tanzania, considered entirely high-risk for malaria. METHODS: [...] health and geo-location data were collected using a smartphone...
The influence of malaria control interventions and climate variability on changes in the geographical distribution of parasite prevalence in Kenya... (Publications)
The burden of malaria in Kenya was showing a declining trend, but appears to have reached a plateau in recent years. This study estimated changes in the geographical distribution of malaria parasite risk [...] contribution of malaria control interventions and climatic/ environmental factors to these changes. METHODS: Bayesian geostatistical models were used to analyse the Kenyan 2015 and 2020 Malaria Indicator Survey [...] coverage of most malaria indicators related to Insecticide Treated Nets...
Modelling the relationship between malaria prevalence as a measure of transmission and mortality across age groups (Publications)
prevalence has been used widely as a measure of malaria transmission, especially in malaria endemic areas. However, its contribution and relationship to malaria mortality across different age groups has not [...] all-cause and malaria-specific mortality. CONCLUSION: Malaria parasitaemia from cross-sectional surveys was associated with mortality across age groups over 4 to 5 year periods with clinical malaria more strongly [...] surveys from the Kisumu HDSS between 2007 and 2015 were used to...
Videographic analysis of flight behaviours of host-seeking <em>Anopheles arabiensis</em> towards BG-Malaria trap (Publications)
The BG-Malaria trap (BGM) is an adaptation of the well-known BG-Sentinel trap (BGS) with greater trapping efficiencies for anopheline and culicine mosquitoes. Its continued optimization requires greater
Theory of reactive interventions in the elimination and control of malaria (Publications)
in maintaining the disease-free state after achieving malaria elimination (through other interventions). CONCLUSION: RCD alone can eliminate malaria in only a very limited range of settings, where transmission [...] BACKGROUND: Reactive case detection (RCD) is an integral part of many malaria control and elimination programmes and can be conceived of as a way of gradually decreasing transmission. However, it is unclear
Modelling reactive case detection strategies for interrupting transmission of <em>Plasmodium falciparum</em> malaria (Publications)
BACKGROUND: As areas move closer to malaria elimination, a combination of limited resources and increasing heterogeneity in case distribution and transmission favour a shift to targeted reactive interventions [...] strategies vary, and it is unclear which are most effective in achieving elimination. METHODS: OpenMalaria, an established individual-based stochastic model, was used to simulate RCD in a Zambia-like setting
Models of effectiveness of interventions against malaria transmitted by <em>Anopheles albimanus</em> (Publications)
BACKGROUND: Most impact prediction of malaria vector control interventions has been based on African vectors. Anopheles albimanus, the main vector in Central America and the Caribbean, has higher intrinsic [...] Hispaniola and intervention effect data from southern Mexico were used to parameterize mathematical malaria models. Indoor residual spraying (IRS), insecticide-treated nets (ITNs), and house-screening were [...] excito-repellency. It also supports the idea that housing improvements have...
