Results of the logistic regression model used to assess the association between the potential risk factors sex, age and species and the outcome variable PPR serological status. Wereda is included as a random effect to account for clustering within weredas. The only factor significantly associated with the odds of positive serological status is the age of the animal (P < 0.01). Animals over 3 years old have almost twice the odds of been positive than animals under 2 years old.
