Maps reveal animal-borne disease as heavy burden for 1 billion of world's poor; new evidence on zoonotic emerging disease hotspots in US and Western Europe A new global study mapping human-animal diseases like tuberculosis (TB) and Rift Valley fever finds that an "unlucky" 13 zoonoses are responsible for 2.4 billion cases of human illness and 2.2 million deaths per year. The vast majority occur in low- and middle-income countries. The report, which was conducted by the International...

New approach to Rift Valley fever outbreaks aims to ensure food safety as region boosts livestock imports from Africa With increased trade in livestock products offering a possible antidote to high food prices, livestock experts from the Middle East and 12 African countries are meeting this week in Dubai to develop a strategy that eliminates the need to impose devastating bans on livestock imports from the Horn of Africa, as prevention against the spread of Rift Valley fever. The strategy...

Two new approaches could form the basis for the first-ever human vaccine for Rift Valley Fever (RVF), an infectious disease that threatens both farm animals and people, say researchers at the University of Pittsburgh Center for Vaccine Research. Reported in this week's PLoS Neglected Tropical Diseases, experimental vaccines developed with these approaches produced strong immune responses in mice and may be safer than the only available RVF vaccine, which is limited to animal use. Although RVF...

The world's top agency for animal health said on Monday that climate change is widening viral disease among farm animals, expanding the spread of some microbes that are also a known risk to humans, AFP reported. A survey of 126 member-states found 71 percent were "extremely concerned" about the expected impact of climate change on animal disease, according to The World Animal Health Organization"”known as OIE, an acronym of its name in French. Among those surveyed, 58 percent said they...

Major virulence factor for Rift Valley fever virus found to have dual mechanism Researchers at the University of Texas Medical Branch at Galveston have discovered a key tactic that the Rift Valley fever virus uses to disarm the defenses of infected cells. The mosquito-borne African virus causes fever in humans, inflicting liver damage, blindness and even death on a small percentage of the people it infects. Rift Valley fever also afflicts cattle, goats and sheep, resulting in a nearly 100...

The U.S. space agency says it used an early warning system, more than a decade in development to predict a 2006-07 outbreak of Rift Valley fever in Africa. National Aeronautics and Space Administration researchers, including Assaf Anyamba, a remote sensing scientist with the University of Maryland and NASA's Goddard Space Flight Center, used a blend of NASA and National Oceanic and Atmospheric Administration measurements of sea surface temperatures, precipitation and vegetation cover to...

Ever since scientists first proposed that our planet might be experiencing widespread climate change, concerns have been raised about its implications for the spread of arboviruses "“ viruses carried by arthropods such as mosquitoes, midges and ticks. However, while alterations in temperature and rainfall are important factors in making new territory hospitable to an invading arbovirus, many other forces also play significant parts in new patterns of viral emergence.That's the message...

An academic at Wyoming University has warned that it would be "relatively easy" for terrorists to launch a devastating attack using swarms of insects to spread a deadly disease. "Rift Valley Fever or other diseases could be transported into a country by a terrorist with a suitcase," said Jeffrey Lockwood, a professor of entomology and author of Six-legged Soldiers: Using Insects as Weapons of War. "I think a small terrorist cell could very easily develop an insect-based weapon," he added....

Rift Valley Fever (RVF) is a viral zoonosis that causes fever. It is spread through infected mosquitoes. It was first reported in 1915 in Kenya were it infected livestock. Outbreaks occur across sub-Saharan Africa, and in the "˜77-"˜78 outbreak several million people were infected and thousands died during a violent epidemic. In 1998 the virus killed 400 Kenyans and in 2000 an outbreak occurred in Saudi Arabia and Yemen. The virus causes mild illness with fever, headache, myalgia and...
