Rift Valley fever — An acute, fever causing viral disease that affects domestic animals (such as cattle, buffalo, sheep, goats, and camels) and humans that is most commonly associated with mosquito borne epidemics during years of heavy rainfall. Introduction. Rift Valley fever (RVF) is a viral infection that is harboured in ruminant animals such as cattle, goats and sheep. Animals are mainly affected by this virus but humans can also become infected. Also Known As: RVF. Caused By: Rift Valley Fever Virus — RVFV. Rift Valley Fever (RVF) is a viral zoonotic disease belonging to the family Bunyaviridae in the Phlebovirus genus, possessing a segmented negative sense RNA genome. Diseases caused by viruses.

Rift Valley fever is an acute viral febrile haemorrhagic disease that affects primarily ruminants in Africa and in the Arabian Peninsula (such as cattle, buffalo, sheep, goats and camels). Agent: Rift Valley fever virus (RVFV), an enveloped, single-stranded tripartite RNA virus, belonging to the genus Phlebovirus of the family Bunyaviridae.Reservoir: Livestock (cattle, camels, goats, sheep), wild buffalo, waterbuck, some rodents.

Many conditions can cause abortion in sheep and goats. The most frequent are: Infectious Enzootic abortion Brucellosis Rift Valley fever Wesselsbron disease Non-infectious Stress and habitual abortion. Rift Valley Fever is caused by a virus that was first isolated in Kenya in 1930, but has since spread throughout Africa and parts of the Middle East.It primarily infects sheep, goats and cattle, although the disease also affects humans so it is a zoonosis.

Rift Valley fever (RVF) is a viral disease that can cause mild to severe symptoms. The mild symptoms may include: fever, muscle pains, and headaches which often last for up to a week. The severe symptoms may include: loss of sight beginning three weeks after the infection Distribution of Rift Valley Fever in Africa. Blue, countries with endemic disease and substantial outbreaks of RVF green, countries known to have some cases, periodic isolation of virus, or serologic evidence of RVF. Animals such as cows, sheep, goats, and camels may be affected.In Egypt in 197778, an estimated 200,000 people were infected and there were at least 594 deaths. Distribution of Rift Valley fever in Africa: Blue, countries with endemic.

RVF is most commonly associated with mosquito-borne epidemics during years of unusually heavy rainfall. Rift Valley fever (RVF) is a viral zoonosis that primarily affects animals but also has the capacity to infect humans.In animals RVFV causes severe disease in ruminants like cattle, sheep, camels and goats. Factors associated with Rift Valley fever in South-West Saudi Arabia.The sera were collected between 1992 and 1995 from cattle, sheep and goats from various locations in Saudi Arabia. Rift Valley fever (RVF) is a zoonotic viral disease that can affect a variety of species, including ruminants and camels, causing highAbortions, apparently unrelated to the gestation period, are the most characteristic sign in adult sheep, goats and cattle. There are also reports of abortions in wild EPIDEMIOLOGY. RVF is a vector-borne disease of sheep, cattle and goats susceptibility of different breeds to RVF varies considerably.For more detailed information regarding laboratory diagnostic methodologies, please refer to Chapter 2.1.14 Rift Valley fever in the latest edition of the OIE Manual Rift Valley Fever. Causes: Sheep, goats, cattle, very young puppies, and humans are affected by this virus-caused disease. Symptoms: High abortion rate occurs in adults and high death losses among very young animals. Rift Valley fever (RVF) is an acute, fever-causing viral disease most commonly observed in domesticated animals (such as cattle, buffalo, sheep, goats, and camels), with the ability to infect and cause illness in humans. ABSTRACT. This blinded field safety study was conducted in Senegal to assess safety and immunogenicity of administration of the registered dose of Rift Valley fever virus (RVFV) Clone 13 vaccine (Onderstepoort Biological Products) to sheep and goats of West African breeds under Clinical signs of RVF. Sudden onset of abortion storms Up to 100 percent mortality in lambs under five to six days old High fever, lymphadenitis, nasal and ocular discharges inThe clinical signs of RVF in sheep and goats have been classified into four groups according to the severity of the disease. Oct 19, 2016 rift valley fever (rvf) is an acute, causing viral disease most commonly observed in domesticated animals (such as cattle, buffalo, sheep, goats, and camels), with the ability to infect cause illness humans. Rift Valley Fever is mosquito-borne virus that is endemic in parts of Africa including South Africa. It primarily infects animals like sheep, cattle and goats and it can have an economic impact on a community due to the loss of livestock. Following the Rift Valley fever (RVF) epizootic of I987 in the Senegal River basin, 2 series of serosurveys were carriedout. In 1988 and 1989, respectively, 303 and 331 randomly selected sheep and goats were investigated and sera tested for the presence of specific Rift Valley fever (RVF) is a viral disease that can cause mild to severe symptoms. The mild symptoms may include: fever, muscle pains, and headaches which often last for up to a week.Animals such as cows, sheep, goats, and camels may be affected. In this study, sera from sheep and goats were collected from 3 regions in Saudi Arabia. They were evaluated for antibodies specific to sheep and goat pox, peste des24.

PLoS Negl Trop Dis. 5 Rift Valley fever in Africa causes abortions in sheep, cattle and goats high mortalities in lambs and kids and generalized disease in man.8 Rift Valley Fever RVF was first observed when European stocks of domestic animals were introduced to Africa. Rift Valley fever: A viral disease that is acute, causes fever in domestic animals (such as cattle, buffalo, sheep, goats, and camels) and humans, and is associated with mosquito-borne epidemics during years of heavy rainfall. Abstract: Four large outbreaks of Rift Valley Fever (RVF) occurred in Mauritania in 1998, 2003, 2010 and 2012 which caused lots of animal and several human deaths.RVF mainly affects domestic animals (cattle, goats, sheep and camels, among others) and generally causes abortions in pregnant Rift Valley Fever is fast spreading viral fever that can affect humans as well as animals such as goats, sheep and cattle. Mosquitoes are one of the main carriers of rift valley virus from animals to humans and vice-versa. Keywords: Rift Valley Fever, RVF, Seroprevalence, domestic, sheep, goats, Mozambique. Overview. Rift Valley fever (RVF) is a viral zoonosis that primarily affects animals but also has the capacity to infect humans.RVF is able to infect many species of animals causing severe disease in domesticated animals including cattle, sheep, camels and goats. Today Rift Valley Fever, or RVF, has spread throughout Africa.For now it shall be discussed as it occurs in livestock. Rift Valley Fever can occur in cattle, camels, and goats, but is most often seen in sheep. Prevalence of antibodies to Rift Valley fever (or closely related) virus in sheep and goats from Rajasthan, India: a preliminary report. Indian Journal of Virology, 11(1):59-60 7 ref. Kitchen SF, 1950.

Rift Valley fever is a zoonosis. It is a contagious disease which is also spread by mosquitoes. The disease affects mainly cattle, sheep and goats and because of its serious nature, it is controlled by the State. Rift Valley Fever is more severe and widespread among domestic animals than it is amongst humans. The three main herds of the regions ( sheep, goats, and cattle each react differently to the virus. Sheep are hit the worst, while goats fare best.
