Rift Valley fever (RVF) is a viral zoonosis that primarily affects animals and has the capacity to infect humans. The socio- economic impact of the disease on livelihoods and trade is high due to significant losses in livestock production, closure of livestock markets and bans on livestock trade. This analytical study showed that the export of live sheep in Sudan has decreased by 55% from 1,616,363 in 1999 to 731,242 in 2000 and sharply by 98% from 731,242 in 2000 to 15,417 in 2001  due to the livestock import ban following the outbreak of RVF in Saudi Arabia in 2000. Following the ban lift, the live sheep export increased rapidly to reach 1,422,209 in 2006. Due to the 2007 RVF outbreak in Sudan, the export volume has decreased by 56% to 615,843 in 2007 and again it increased gradually to reach 3,757,363 in 2013 due to efforts made to overcome the livestock trade restrictions following the 2007 RVF outbreak. Correlation analysis made to measure sheep export in relation to RVF outbreaks; the results gave a coefficient of -0.489 implying a negative correlation.  This means that when an RVF outbreak occurs, the model predicts that the sheep export drops by 49%.
