ABSTRACT
Rift Valley fever (RVF) is an arthropod-borne infection affecting a wide range of vertebrates including humans. Rift Valley fever virus (RVFV) was initially considered as a major veterinarian pathogen with a dramatic impact on domestic livestock’s health. In 1977, the widest epizootic/epidemic recorded yet occurred in Egypt, revealing new epidemiological features and particularly the role of human activities in the spreading of the virus.
