Preliminary Qualitative Risk Assessment for Peste des petits ruminants (PPR) in Sheep Exported from Sudan During 2012

The overall risk of PPR spreading in sheep exports was estimated to be Low. The PPR released risk in sheep value chain, which represent the probabilities of PPRV existence in sheep herds prior to send to livestock markets, within markets, in addition to the virus probabilities to spread in the internal quarantine, was found to be Medium (which means that the risky event is likely to occur more than once in the next three years). The exposure risk which represent the probability of PPRV to spread among the sheep herds selected for exportation and it is depending on the contact with an infected sheep or fomites within the transporting trucks to the terminal quarantine or/and in the terminal quarantine or/and in the fomites of the transporting ship to the importing country. In this study the exposure risk was assessed to be very low (that means the risk of PPRV spread is rare, the risky event mayoccur in exceptional circumstances).
