Towards empirical description of malaria seasonality in southern Africa: the example of Zimbabwe (Publications)
BACKGROUND: Quantitative description and mapping of malaria seasonality is important for timely spatial targeting of interventions and for modelling malaria risk. There is a need for seasonality models that [...] use Zimbabwe as an example for developing an empirical map of malaria seasonality. We describe the relationship between seasonality in malaria and environmental covariates for the period 1988--1999, by fitting [...] seasonal trend. We adapt a seasonality concentration index used...
Socially marketed insecticide-treated nets improve malaria and anaemia in pregnancy in southern Tanzania (Publications)
CONCLUSIONS: A modest impact of ITNs on pregnancy malaria and anaemia was shown in our high malaria transmission setting. The development of ITN programmes for malaria control should include pregnant women as a [...] no anaemia, and of high density, low density and no malaria infection by ITN status. Recently treated nets were most effective at preventing malaria and anaemia (prevalence of mild anaemia was 68% compared [...] OBJECTIVES: To study the uptake of socially marketed...
Environmental predictors of the seasonality of malaria transmission in Africa: the challenge (Publications)
A description of malaria seasonality is important for planning and optimizing malaria control in both time and space, but adequate malariologic data are not available for many disease-endemic areas. We [...] between the seasonal dynamics of environmental determinants and malaria pose a great challenge and highlights the need for improved models of malaria seasonality
Residual antimalarial concentrations before treatment in patients with malaria from Cambodia: indication of drug pressure (Publications)
at reducing inappropriate drug use. Methods. Baseline samples from 125 patients with falciparum malaria recruited for 2 in vivo studies (in Preah Vihear and Pursat provinces) were analyzed for the presence [...] (25% and 35% of patients) and piperaquine (15% of patients); the first-line drug against vivax malaria, chloroquine (25% and 41% of patients); and the former first-line drug, quinine (5% and 34% patients)
Consistently high estimates for the proportion of human exposure to malaria vector populations occurring indoors in rural Africa (Publications)
eated nets (ITNs) and indoor residual spraying (IRS) are highly effective tools for controlling malaria transmission in Africa because the most important vectors, from the Anopheles gambiae complex and
Cost-effectiveness of malaria intermittent preventive treatment in infants (IPTi) in Mozambique and the United Republic of Tanzania (Publications)
on the efficacy results of the intervention and on malaria incidence in the target population, an estimate was made of the number of clinical malaria episodes prevented. This number and an assumed cas [...] OBJECTIVE: To estimate the cost-effectiveness of malaria intermittent preventive treatment in infants (IPTi) using sulfadoxine-pyrimethamine (SP). METHODS: In two previous IPTi trials in Ifakara (United [...] costs, was then assessed on the basis of these figures. FINDINGS: The cost per...
