Summary In 2015, the lumpy skin disease virus spread throughout the Russian Federation. Following a modified stamping‐out campaign, the disease re‐emerged with a greater incidence across 16 regions of Southern and Central Russia. A total of 313 outbreaks were reported to OIE . The highest outbreak frequency was observed in the republics of Chechnya (108), Kalmykiya (57), and Ingushetiya (35). The disease cases predominantly occurred in June and July 2016, starting from May to December; however, no association between outbreaks and altitudes was identified ( p > .05). Samples taken from infected cattle were subjected to PCR analysis, which identified the genome of the virus most frequently in skin nodules (78%), nasal swabs (23.4%), blood (13%) and sera (14.5%). Interestingly, LSDV genome was occasionally identified in lung and milk samples. Based on the PRO 30 sequence analysis, lumpy skin disease virus ( LSDV ) strains circulating in Russia were all identical and fell within the cluster of field LSDV found worldwide.
