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...

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...

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....
