This study, carried out between September 2006 and January 2007, is the first cross-sectional serological investigation of peste-des-petits-ruminants (PPR) and Rift Valley fever (RVF) in Tunisia. The objective was to assess the potential need to develop a dual, recombinant PPR-RVF vaccine and how such a vaccine might be utilized in Tunisia. An overall PPR seroprevalence of 7.45% was determined, a finding supported by the high specificity (99.4%) and sensitivity (94.5%) of the ELISA used. On assessment of the diversity and density of mosquitoes in the sampling area, four species of RVF-vectors of the genus Aedes and Culex were identitied. However, no serological evidence of RVF was found despite the use of a highly sensitive ELISA (99-100%).Larger scale investigations are underway to confirm these findings and the continuation of the emergency vaccination program against these two diseases remains valid.
