RVF

It has been used experimentally to protect veterinary and laboratory personnel at high risk of exposure to RVF.

The virus may be detectable in the blood for up to 10 days, in patients with the hemorrhagic icterus form of RVF.

It introduced the effects of energy consumption reduction for the domestic RVF technology used in PTA plant.

Several different species of mosquito are able to act as vectors for transmission of the RVF virus.

As most human cases of RVF are relatively mild and of short duration, no specific treatment is required for these patients.

Outbreaks of RVF in animals can be prevented by a sustained programme of animal vaccination.

Intractable rectovaginal fistula (RVF) is a troublesome complication after treatment of perineal cancers or infection.

Most of these cases reported direct contact with RVFV-infected livestock and or linked to farms with confirmed animal cases of RVF.

Other ways in which to control the spread of RVF involve control of the vector and protection against their bites.

The appearance of RVF disease in humans is typically preceded by infection in animals.

The disease also results in significant economic losses due to death and abortion among RVF-infected livestock.

RVF virus is a member of the Phlebovirus genus, one of the five genera in the family Bunyaviridae.

In RVF outbreaks, the vast majority of human infections result from direct or indirect contact with the blood or organs of infected animals.

Human cases of Rift Valley fever (RVF) continue to occur in Sudan, with more than 221 cases reported in the last two weeks.

Humans may also become infected with RVF by ingesting the unpasteurized or uncooked milk or meat of infected animals.

Sporadic cases of RVF infection in animals have been documented in South Africa in recent years.

The RVF virus circulates between ruminant animals (cattle, sheep, goats, and camels) via mosquitoes.

Laboratory results from three cases in Khartoum state have been found negative for RVF.

Only severe cases of RVF were detected through surveillance and of the 264 cases, 154 (60%) were laboratory confirmed.

In Africa, Saudi Arabia and Yemen RVF outbreaks are closely associated with periods of above-average rainfall.

It also summed up experiences and optimization of equipment layout of the domestic RVF.

Acute RVF can be diagnosed using several different methods.

There is some evidence that humans may also become infected with RVF by ingesting the unpasteurized or uncooked milk of infected animals.

Several of the newly added cases evidence ocular presentation, which is typically a late-occurring feature of RVF infection.

The incubation period (interval from infection to onset of symptoms) for RVF varies from two to six days.

Human cases of Rift Valley fever (RVF) in Sudan have decreased continuously in recent weeks.

This approach may be another alternative to resolve a complex RVF.

Transmission of RVF virus by hematophagous (blood-feeding) flies is also possible.

More than 25 human samples have been found positive for RVF by PCR or ELISA.

There has been no evidence of outbreaks of RVF in urban areas.

As of 21 November 2007, 436 human RVF cases, including 161 deaths have been reported from White Nile, Sennar, and Gazeera States.

Human cases of Rift Valley Fever (RVF) continue to increase, with 228 cases and 84 deaths reported as of 7 November.

Rift Valley fever (RVF) is a viral zoonosis that primarily affects animals but also has the capacity to infect humans.

From 30 November 2006 to 12 March 2007, a total of 684 cases including 155 deaths (case-fatality ratio, 23%) of RVF was reported in Kenya.

We presented a 46 years old woman with posterior wall RVF after the rectal cancer surgery.
