This research correlates the effect of climatic factors on bluetongue epidemiology in sheep of delta districts in Tamilnadu based on merteriological data collected from 2014 to 2016. There are a total of eighty two villages of delta districts were affected with Blue tongue virus (BTV). We used multiple linear regression analysis to assess the effect of climatic factors on the prevalence of bluetongue. Our results showed that maximum temperature, rain fall and relative humidity positively correlates with the number of BTV epidemic in sheep flocks. These findings suggest that the risk of BTV infections in sheep increased in warm and humid environments. Moreover, climatic factors can be used to forecast the possible epidemic in this area and other regions characterized by similar climatic conditions.
