FMDV infection prevalence at aggregate level in tabular form. FMDV infection prevalence at aggregate level from April 2006 to April 2007, based on the number of inapparently infected animals found in a two-stage sampling scheme. The farm-level (herd-level) prevalence reflects the number of farms with positive found animals, calculated as the proportion of Σ farms infected per month to Σ farms sampled per month, and the animal-level prevalence reflect the number of positive animals within the sampled population, calculated as the proportion of Σ animals infected per month to Σ animals sampled per month
