Climate Teleconnections and Recent Patterns of Human and Animal Disease Outbreaks
BACKGROUND Recent clusters of outbreaks of mosquito-borne diseases (Rift Valley fever and chikungunya) in Africa and parts of the Indian Ocean islands illustrate how interannual climate variability influences the changing risk patterns of disease outbreaks. Although Rift Valley fever outbreaks have been known to follow periods of above-normal rainfall, the timing of the outbreak events has larg...
متن کاملHead-Mounted Displays for HCI Validations While Driving
To provide reliable and valid findings when evaluating innovative in-car devices in the automotive context highly realistic driving environments are recommended. Nowadays, in-car devices are mostly evaluated due to driving simulator studies followed by real car driving experiments. Driving simulators are characterized by high internal validity, but weak regarding ecological validity. Real car d...
متن کاملEcological niche modelling of Rift Valley fever virus vectors in Baringo, Kenya
BACKGROUND Rift Valley fever (RVF) is a vector-borne zoonotic disease that has an impact on human health and animal productivity. Here, we explore the use of vector presence modelling to predict the distribution of RVF vector species under climate change scenario to demonstrate the potential for geographic spread of Rift Valley fever virus (RVFV). OBJECTIVES To evaluate the effect of climate ...
متن کاملRift Valley Fever (RVF) Case Study – Dynamic Drivers of Disease in Africa: Ecosystems, livestock/wildlife, health and wellbeing
One of our remarkable research outputs to date, produced as part of a graduate fellowship programme, is an ecological niche map for RVF in Kenya. The student involved, Dr Purity Kiunga, initiated the study by georeferencing known RVF hotspots in Kenya and analysing them together with spatial datasets on precipitation, rainfall, soil types, land use and vegetation indices. The work has generated...
متن کاملAssociation of ecological factors with Rift Valley fever occurrence and mapping of risk zones in Kenya.
OBJECTIVE Rift Valley fever (RVF) is a mosquito-borne infection with great impact on animal and human health. The objectives of this study were to identify ecological factors that explain the risk of RVF outbreaks in eastern and central Kenya and to produce a spatially explicit risk map. METHODS The sensitivity of seven selected ecological variables to RVF occurrence was assessed by generaliz...
