A Rift Valley fever (RVF) epidemic affecting animals on domestic livestock farms was reported in South Africa during January-August 2010. The first cases occurred after heavy rainfall, and the virus subsequently spread countrywide. To determine the possible effect of environmental conditions and vaccination on RVF virus transmissibility, we estimated the effective reproduction number (Re) for t...

Rift Valley fever is a viral disease that affects domestic animals and humans. In humans, Rift Valley fever causes a flu-like disease but occasionally leads to high morbidity and mortality. The disease is generally known in the African continent. However, cases started to appear in Saudi Arabia and Yemen. The objective of this review is to give a general briefing about the epidemiology, ecology...

• Prevention and control In today’s presentation we will cover information on what causes Rift Valley Fever. We will also talk about the history of the disease, where it is distributed, species that it affects (including humans), and signs of illness observed. Finally, we will address prevention and control measures for Rift Valley Fever virus. This will include control of mosquitoes and their ...

Development of safe and efficacious vaccines whose potency is unaffected by long-term storage at ambient temperature would obviate major vaccine deployment hurdles and limit wastage associated with breaks in the vaccine cold chain. Here, we evaluated the immunogenicity of a novel chimpanzee adenovirus vectored Rift Valley Fever vaccine (ChAdOx1-GnGc) in cattle, following its thermostabilisation...

Sheep and goat pox, peste des petits ruminants and Rift Valley fever are important diseases of small ruminant livestock. Sheep and goat pox, along with peste des petits ruminants, are endemic throughout most of Africa, Asia and the Middle East. Whereas Rift Valley fever is endemic in Africa, outbreaks in the Middle East have been reported over the past decade, including the Arabian Peninsula. S...

It is unclear how language influences colour perception so as to lead to the categorical perception of colour. This is particularly true when considering visual tasks that involve minimal memory requirements. In the present experiment we investigated this question by employing a "same-different" judgment task in which participants were asked to compare the colours of two presented visual featur...

Postprint This is the accepted version of a paper published in Protein Expression and Purification. This paper has been peer-reviewed but does not include the final publisher proof-corrections or journal pagination. Arabidopsis thaliana plants expressing Rift Valley fever virus antigens: Mice exhibit systemic immune responses as the result of oraladministration of the transgenic plants. Access ...

Rift Valley fever (RVF) is a zoonotic viral disease that can affect a variety of species, including ruminants and camels, causing high mortality in young animals and/or abortions in adults. The RVF virus is endemic mainly in subSaharan Africa, but it has also been seen in North Africa, and may have become established in Egypt. There are concerns that this virus might be spreading, after outbrea...

After the 2006-2007 epidemic wave of Rift Valley fever (RVF) in East Africa and its circulation in the Comoros, laboratory case-finding of RVF was conducted in Mayotte from September 2007 through May 2008. Ten recent human RVF cases were detected, which confirms the indigenous transmission of RFV virus in Mayotte.

BACKGROUND To date, Alphavirus infections and their most prominent member, chikungunya fever, a viral disease which first became apparent in Tanzania in 1953, have been very little investigated in regions without epidemic occurrence. Few data exist on burden of disease and socio-economic and environmental covariates disposing to infection. METHODS A cross-sectional seroprevalence study was un...
