Spatial distribution of<em> Falciparum</em> malaria infections in Zanzibar: implications for focal drug administration strategies targeting... (Publications)
Background.: Optimal use of mass/targeted screen-and-treat or mass or focal drug administration as malaria elimination strategies remains unclear. We therefore studied spatial distribution of Plasmodium
Mosquito behavior change after distribution of bednets results in decreased protection against malaria exposure (Publications)
efficacy of vector control in reducing malaria transmission. Methods.: In this study, we quantified human exposure to both bites and infective bites of a major malaria vector in Papua New Guinea over the [...] the course of 4 years surrounding nationwide bednet distribution. We also quantified malaria infection prevalence in the human population during the same time period. Results.: We observed a shift in mosquito [...] period and was lowest in the adult population, who may be an important...
Asymptomatic and sub-microscopic malaria infection in Kayah State, eastern Myanmar (Publications)
be targeted for malaria elimination. METHODS: A mass blood survey was conducted among 485 individuals from six villages in Kayah State, an area of endemic but low transmission malaria in eastern Myanmar [...] BACKGROUND: Myanmar has the heaviest burden of malaria in the Greater Mekong Sub-region. Asymptomatic Plasmodium spp. infections are common in this region and may represent an important reservoir of t [...] Myanmar. Malaria infection was screened by rapid diagnostic test (RDT), light...
Higher complexity of infection and genetic diversity of <em>Plasmodium vivax </em>than <em>Plasmodium falciparum</em> across all malaria transmission... (Publications)
New Guinea (PNG) to evaluate transmission dynamics across the country. In 2008-2009, a nationwide malaria indicator survey collected 8,936 samples from all 16 endemic provinces of PNG. Of these, 892 positive
An investment case to prevent the reintroduction of malaria in Sri Lanka (Publications)
in reducing the burden of malaria, recording no locally transmitted malaria cases since November 2012 and zero deaths since 2007. The country was recently certified as malaria free by World Health Organization [...] due to persistent receptivity and vulnerability to malaria transmission. Maintaining the gains will require continued sustainability to the malaria program to maintain the activities aimed at preventing [...] economic cost of the malaria program in 2014 was estimated at U.S. dollars...
The relative contribution of climate variability and vector control coverage to changes in malaria parasite prevalence in Zambia 2006-2012 (Publications)
BACKGROUND: Four malaria indicator surveys (MIS) were conducted in Zambia between 2006 and 2012 to evaluate malaria control scale-up. Nationally, coverage of insecticide-treated nets (ITNs) and indoor [...] on malaria parasite prevalence over this period. METHODS: Nationally-representative MISs were conducted in April-June of 2006, 2008, 2010 and 2012 to collect household-level information on malaria control [...] between IRS and ITN coverage and climate variability and malaria parasite...
A crossover study to evaluate the diversion of malaria vectors in a community with incomplete coverage of spatial repellents in the Kilombero Valley,... (Publications)
BACKGROUND: Malaria elimination is unlikely to occur if vector control efforts focus entirely on transmission occurring indoors without addressing vectors that bite outdoors and outside sleeping hours [...] Kilombero, Tanzania. The density of resting and blood-engorged mosquitoes and human blood index (HBI) of malaria vector species per household was measured among 90 households using or not using 0.03 % transfluthrin [...] non-users. The repellent coils did not affect An. funestus densities or...
The effect of mass mosquito trapping on malaria transmission and disease burden (SolarMal): a stepped-wedge cluster-randomised trial (Publications)
clinical malaria episodes were recorded in intervened clusters and 33 episodes in non-intervened clusters (adjusted effectiveness 40.8% [95% CI -172.8 to 87.1], p=0.5) during the roll-out. Malaria prevalence [...] unexpectedly low clinical incidence of malaria during roll-out led to an imprecise estimate of effectiveness from the clinical incidence data. The substantial effect on malaria prevalence is explained by reduction [...] mosquitoes indoors and outdoors. We assessed the effects of mass...
