Abstract

A study was conducted with the objective to determine the risk factors of Foot and Mouth Disease (FMD) outbreak occurrence in Samdrup Jongkhar district in Bhutan. Twenty-six household that had experienced FMD outbreak and diagnosed as FMD in cattle between January 2012 and December 2015 were defined as a case. Two households that owned cattle and had not experienced any outbreaks of FMD within the same village were selected as control. Data related to management and environmental factors were collected with the questionnaire survey during November and December 2016.
