Behavioural determinants of gene flow in malaria vector population: <em>Anopheles gambiae</em> males select large females as mates (Publications)
transgenic vectors. Fundamental studies of behavioural ecology in malaria vectors such as An. gambiae can have important implications for malaria control and should be prioritised for more extensive investigation [...] BACKGROUND: Plasmodium-refractory mosquitoes are being rapidly developed for malaria control but will only succeed if they can successfully compete for mates when released into the wild. Pre-copulatory [...] structure in wild mosquito populations and mating barriers have foiled...
Malaria transmission after five years of vector control on Bioko Island, Equatorial Guinea (Publications)
ABSTRACT: BACKGROUND: Malaria is endemic with year-round transmission on Bioko Island. The Bioko Island Malaria Control Project (BIMCP) started in 2004 with the aim to reduce malaria transmission and to [...] to ultimately eliminate malaria. While the project has been successful in reducing overall malaria morbidity and mortality, foci of high malaria transmission still persist on the island. Results from the
Three different <em>Plasmodium</em> species show similar patterns of clinical tolerance of malaria infection (Publications)
data on the age dependence of tolerance in other species of human malaria. METHODS: Parasite densities measured in 24,386 presumptive malaria cases at two local health centres in the Wosera area of Papua New [...] to the logarithm of the parasite density for all three malaria species, with little age variation in the relationship for P. vivax or P. malariae. P. falciparum shows more age variation in disease incidence [...] BACKGROUND: In areas where malaria endemicity is high, many people...
Allomonal effect of breath contributes to differential attractiveness of humans to the African malaria vector Anopheles gambiae (Publications)
contributes to between-person differences in relative attractiveness to the highly anthropophilic malaria vector Anopheles gambiae sensu stricto remains unknown and was the focus of the present study. METHODS: [...] contributor to between-person differences in the relative attractiveness of humans to this important malaria vector
Interpreting malaria age-prevalence and incidence curves: a simulation study of the effects of different types of heterogeneity (Publications)
Individuals in a malaria endemic community differ from one another. Many of these differences, such as heterogeneities in transmission or treatment-seeking behaviour, affect malaria epidemiology. The [...] heterogeneity were incorporated into a comprehensive individual-based model of Plasmodium falciparum malaria epidemiology. The different types of heterogeneity were systematically simulated individually, and
The acceptability of intermittent preventive treatment of malaria in infants (IPTi) delivered through the expanded programme of immunization in... (Publications)
BACKGROUND: Intermittent preventive treatment of malaria in infants (IPTi) reduces the incidence of clinical malaria. However, before making decisions about implementation, it is essential to ensure that [...] attitudes or adherence to the expanded programme on immunisation (EPI) or treatment seeking or existing malaria prevention. CONCLUSION: In order to improve adherence to both EPI and IPTi local priorities should
Care-seeking patterns for fatal malaria in Tanzania (Publications)

Care-seeking behaviours may differ between these groups. [...] children less than five years of age with fatal malaria seen between 1999 and 2001 during over 240,000 person-years of follow-up in a stable perennial malaria transmission setting in southern Tanzania. Accounts [...] respectively. CONCLUSIONS: In this study of fatal malaria in southern...
The cost-effectiveness of intermittent preventive treatment for malaria in infants in Sub-Saharan Africa (Publications)
a pooled PE for IPTi with SP, malaria incidence, an estimated malaria case fatality rate of 1.57%, IPTi delivery costs and country specific provider and household malaria treatment costs. FINDINGS: In [...] effect on clinical malaria. CONCLUSIONS: IPTi delivered alongside the EPI is a highly cost effective intervention against clinical malaria with a range of drugs in a range of malaria transmission settings [...] treatment in infants (IPTi) has been shown to decrease clinical malaria by...
