Risk of foot and mouth disease spread through cattle movements in Uganda.

Foot and mouth disease (FMD) is endemic in Uganda, where livestock movements through porous borders and beyond play a key role in the spread of transboundary animal diseases. Data from published and unpublished sources were used to conduct a qualitative risk assessment based on the World Organisation for Animal Health framework to assess the risk of foot and mouth disease virus spread in Uganda through pastoral and trade-related cattle movements from the country's southern border districts. A scenario tree was developed as a conceptual framework, and the risk was assessed by considering factors including the cattle population, proportion of vaccinated cattle, number of live cattle legally moved from districts along the Ugandan-Tanzanian border, the production system in the destination districts and the purpose of the movement.
