Significant risk factors asso-ciated with seropositivity to CCPP in 2007 included introduction of new animals in flocks(OR = 3.94 95% CI 1.868.36 p < 0.001) and raising animals in government farms (OR = 4.92 95% CI 1.5715.76 p = 0.02) whereas, seropositivity to CCPP in 2009 increased with intro-duction of new animals in flocks (OR = 18.82 95% CI 8.0643.96 p < 0.001), raising animalsin government farms (OR = 4.04 95% CI 2.696.42 p < 0.001) and raising animals in Newaladistrict (OR = 2.35 95% CI 1.533.62 p < 0.001). Mixed infections were detected in7.4% (n = 434) of the goat and 12.9% (n = 70) of sheep samples. Seroconversion to PPR in goatsand sheep was 28.7% (n = 434) and 35.7% (n = 70) respectively based on the sera of 2009.However, no antibodies were detected in the 2007 sera. The overall seroprevalence of CCPP for the sera of 20in goats was 52.1% (n = 447) and 35.5% (n = 434) respectively while in sheep the seropreva-lence was 36.7% (n = 30) and 22.9% (n = 70) respectively. Seroconversions to CCPP and PPR were tested using competitive ELISA.In addition, information on different variables available in the existing surveillance formsgathered during sampling was used in the analysis of risk factors associated with seroposi-tivity to the two diseases. Seroconversion was also evaluated in the 504 sera that were col-lected in 2009 as part of disease outbreak investigations in Tandahimba and Newala districtsof Mtwara region. A total of 477 randomly selected sera from a bank of 3500 small ruminant samples thatwere collected as part of Rift Valley Fever surveillance of 2007 in Mtwara and Lindi regionswere used in this study.
