This government/UN report, the first of its kind since 1993, gives facts and figures not only on trends in spending, but also on trends in outcomes. Inter alia, ‘The Ethiopia National Malaria Indicator Survey (2007) showed that malaria-related deaths fell by 55 per cent nationally, in-patient admissions related to malaria went down by 54 per cent and 14,000 child deaths related to malaria were prevented during 2006 and 2007.Forty two per cent of children under five slept under a bed net thenight before the survey.’

Background. Patterns of concerted fluctuation in populations—synchrony—can reveal impacts of climatic variability on disease dynamics. We examined whether malaria transmission has been synchronous in an area with a common rainfall regime and sensitive to the Indian Ocean Dipole (IOD), a global climatic phenomenon affecting weather patterns in East Africa.
Methods. We studied malaria synchrony in 5 15-year long (1984–1999) monthly time series that encompass an altitudinal gradient, approximately 1000 m to 2000 m, along Lake Victoria basin. We quantified the association patterns between rainfall and malaria time series at different altitudes and across the altitudinal gradient encompassed by the study locations.
Results. We found a positive seasonal association of rainfall with malaria, which decreased with altitude. By contrast, IOD and interannual rainfall impacts on interannual disease cycles increased with altitude. Our analysis revealed a nondecaying synchrony of similar magnitude in both malaria and rainfall, as expected under a Moran effect, supporting a role for climatic variability on malaria epidemic frequency, which might reflect rainfall-mediated changes in mosquito abundance.
Conclusions. Synchronous malaria epidemics call for the integration of knowledge on the forcing of malaria transmission by environmental variability to develop robust malaria control and elimination programs.
