Vet Med Today: Zoonosis Update 883 R Valley fever virus is a mosquito-borne pathogen of livestock and humans that historically has been responsible for widespread and devastating outbreaks of severe disease throughout Africa and, more recently, the Arabian Peninsula. The virus was first isolated and RVF disease was initially characterized following the sudden deaths (over a 4-week period) of approximately 4,700 lambs and ewes on a single farm along the shores of Lake Naivasha in the Great Rift…

Rift Valley Fever: Recent Insights into Pathogenesis and Prevention

Progress in understanding the epidemiology of Rift Valley fever has enabled prediction of potential outbreaks well in advance, thus providing another tool to combat the physical and economic impact of this disease.

RIFT VALLEY FEVER VIRUS VACCINE STRATEGIES

It is shown that the inactivated virus vaccine is well‐suited for that purpose until more effective alternatives are available, and the question of extending the vaccination program in Mozambique to include Maputo Province is raised.

Tempering the risk: Rift Valley fever and bioterrorism

The classification of RVFV as a potential bioterrorism agent has spurred investment and activity, particularly in the area of vaccine development and diagnostics, and a more longstanding, parallel interest in the disease has also developed internationally; one centred around the biosecurity implications of the virus.

Unless vaccines are available and widely used to limit its expansion, Rift Valley fever will continue to be a critical issue for human and animal health in the region of the Indian Ocean.

A Serological Study of Rift Valley Fever Virus in Two Regions in Tanzania

The majority of the seropositive sheep and goats from all the three sampling sites were younger than seven years, indicating that RVFV circulates in low levels in the Arusha and Morogoro region during the inter-epidemic period.

Epidemiological study of Rift Valley fever virus in Kigoma, Tanzania.

This study has confirmed, for the first time, the presence of the RVFV in the Kigoma region four years after the 2007 epizootic in Tanzania, and suggests that the virus activity exists during the inter-epizootics period, even in regions with no history of RVFF.

Modifying the NSs gene to improve live-attenuated vaccine for Rift Valley fever

Considering that a large number of ruminants are infected during RVF outbreaks, RVF vaccines should rapidly induce high levels of protective neutralizing antibodies in both ruminant and humans with a single dose, which will minimize the impact of RVFV introduction into nonendemic countries.

Prevalence of antibodies against Rift Valley fever virus in Kenyan wildlife

Data provide evidence that wild ruminants are infected by RVFV but further studies are required to determine whether these animals play a role in the virus maintenance between outbreaks and virus amplification prior to a noticeable outbreak.

The Pathogenesis of Rift Valley Fever

The pathology of RVF in human patients and several animal models is described, and the role of viral virulence factors and host factors that affect RVFV pathogenesis are summarized.

Rift Valley fever in humans in South Africa.

During an epizootic of Rift Valley fever in South Africa in 1974/1975, mainly affecting sheep and cattle, a large number of human cases occurred, and follow-up studies showed that immune rates among residents on affected farms varied from 10% in children to 17,1% in adult males, with an overall immunity rate of 14,5%.

Rift Valley Fever Encephalitis

A case of RVF encephalitis associated with retinitis, including CSF findings, viral culture results, and neuroradiology findings is described, involving an 18-year-old woman from Jazan (southwest of Saudi Arabia) who had a 3-day history of confusion, fever, and blurred vision at the time an RVF outbreak was peaking inJazan.

A role for A. namaquensis as a cryptic carrier for RVF virus during interepizootic periods is suggested and the results of other studies suggesting an amplifying role for heavy rainfall in the circulation of RVFirus are supported.
