Rift Valley fever virus (RVFV) is a viral pathogen primarily affecting livestock, particularly sheep, goats, and cattle. It is transmitted through the bites of infected mosquitoes or contact with contaminated animal tissues and fluids. The virus can cause severe disease in animals, leading to high mortality rates, especially in young animals. In humans, RVFV can cause flu-like symptoms, and in some cases, it may lead to more severe complications such as hemorrhagic fever or meningitis. While human infections are less common, outbreaks can occur, particularly in regions where the virus is endemic, such as parts of Africa and the Middle East.
