Rift Valley Fever (RVF) Case Study – Dynamic Drivers of Disease in Africa: Ecosystems, livestock/wildlife, health and wellbeing
نویسنده
چکیده
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 an RVF risk map with a better resolution than existing maps, and it will enable our team to undertake a comparison of RVF drivers at local and national scales.

Planning for Rift Valley fever virus: use of geographical information systems to estimate the human health threat of white-tailed deer (Odocoileus virginianus)-related transmission.
Rift Valley fever (RVF) virus is a mosquito-borne phlebovirus of the Bunyaviridae family that causes frequent outbreaks of severe animal and human disease in sub-Saharan Africa, Egypt and the Arabian Peninsula. Based on its many known competent vectors, its potential for transmission via aerosolization, and its progressive spread from East Africa to neighbouring regions, RVF is considered a hig...
متن کاملSpatial, seasonal and climatic predictive models of Rift Valley fever disease across Africa
Understanding the emergence and subsequent spread of human infectious diseases is a critical global challenge, especially for high-impact zoonotic and vector-borne diseases. Global climate and land-use change are likely to alter host and vector distributions, but understanding the impact of these changes on the burden of infectious diseases is difficult. Here, we use a Bayesian spatial model to...

Rift Valley fever (RVF) is an emerging, vector-borne viral zoonosis that has significantly impacted public health, livestock health and production, and food security over the last three decades across large regions of the African continent and the Arabian Peninsula. The potential for expansion of RVF outbreaks within and beyond the range of previous occurrence is unknown. Despite many large nat...

BACKGROUND Rift Valley fever (RVF) is a fatal arthropod-borne zoonotic disease of livestock and humans. Since the identification of RVF in Kenya in the 1930s, repeated epizootics and epidemics coinciding with El Niño events have occurred in several locations in Africa and Saudi Arabia, causing mass deaths of livestock and humans. RVF is of great interest worldwide because of its negative effect...

Rift Valley fever (RVF) is endemic in many countries in Sub-Saharan Africa and is responsible for severe outbreaks in livestock characterized by a sudden onset of abortions and high neonatal mortality. During the last decade, several outbreaks have occurred in Southern Africa, with a very limited number of cases reported in Botswana. To date, published information on the occurrence of RVF in wi...
