Abstract: The aim of the current study is to develop a methodology able to identify, classify and monitor the reintroduction risk points of foot-and-mouth disease (FMD) in order to support an epidemiology monitoring system. The study was conducted in Maranhão State. The methodology was developed in six stages, namely: i) identifying the reintroduction risk points of foot-and-mouth disease; (ii) assessing the risk per identified point; iii) classifying the risk points; iv) analyzing the spatial distribution of risk points; v) identifying livestock properties under the highest epidemiological risk in comparison to the identified risk points; and vi) systematizing the model used to monitor risk points and livestock properties under the highest epidemiological risk. It was possible identifying and mapping possible points of introduction and/or dissemination of vesicular diseases in 2013 (917 points), 2014 (943 points) and 2015 (886 points). Three hundred and twenty-seven (36.91%) out of the 886 points identified in 2015 were classified as of low risk; 55.87% (n = 495), as of medium risk; and 7.22% (n = 64), as of high risk. The identified points were monitored on a monthly basis, as indicated for the herein assessed risk level, and it totaled 5,021; 5,382 and 5,441 inspections, respectively. Livestock properties under the highest epidemiological risk were also identified, and it totaled 2,894 properties in 2013; 3,057, in 2014; and 3,159, in 2015. These properties were inspected every six months, and it totaled 2,240; 2,294 and 2,353 inspections, respectively. It was concluded that the methodology enables epidemiologically monitoring the reintroduction risk points of Foot-and-Mouth Disease through risk analysis and geoprocessing in association with classic methods.
