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...
Mass mosquito trapping for malaria control in western Kenya: study protocol for a stepped wedge cluster-randomised trial (Publications)
of malaria threaten the efficacy of existing vector control tools used against malaria mosquitoes. The development of odour-baited mosquito traps has led to the possibility of controlling malaria through [...] mass mosquito trapping could be an effective tool for elimination of malaria. If proven to be effective, this novel approach to malaria control would be a valuable addition to the existing strategies of [...] through mass trapping of malaria vectors. Through daily removal trapping against...
Malaria intervention scale-up in Africa: effectiveness predictions for health programme planning tools, based on dynamic transmission modelling (Publications)
(IRS), management of uncomplicated malaria cases (CM) and seasonal malaria chemoprophylaxis (SMC) over a 10-year horizon, over a range of settings with stable endemic malaria. Generalized linear regression [...] intervention impact, to inform a malaria module in the Spectrum health programme planning tool. METHODS: The dynamic Plasmodium falciparum transmission model OpenMalaria was used to simulate health effects [...] entail a partial rebound in malaria mortality among people above 5 years of...
Community-based surveillance to monitor mortality in a malaria-endemic and Ebola-epidemic setting in rural Guinea (Publications)
a reinforced malaria control program and one sous-prefecture without (Koundou) in Guinea. Deaths were recorded by key informants and classified as due to malaria or another cause. Malaria deaths were those [...] deaths were reported from July 2011-June 2014, of which 55.2% (N = 686) were reported as due to malaria. Malaria-attributable proportional mortality decreased by 26.5% (95% confidence interval [CI] = 13.9-33 [...] those reported as due to malaria or fever in the 3 days before death with...
