Relevance . The relevance of the topic is determined by the fact that an analysis of the epizootic situation of infectious anemia of horses in the Russian Federation has been carried out, with the identification of regions with a high degree of risk for this chronic infection. The dynamics of the spread of the disease in disadvantaged regions for the period 2018–2020 was analyzed. Methods . The main method of laboratory diagnosis of infectious anemia of horses is the study of blood serum in the diffuse precipitation in agar gel (AGID). For the analysis, we used the statistical data presented in the official reporting form 4-vet according to the Order of the Ministry of Agriculture of the Russian Federation dated 02.04.2008 No. 189 (“On the Regulations for the provision of information to the system of state information support in the field of agriculture”). Results . The article presents the results of the analysis of the prevalence of infectious anemia of horses in the country based on the results of serological studies in the AGID performed by the state veterinary laboratories of the constituent entities of the Russian Federation in 2018–2020. In total, 1,426,642 one-hoofed animals were examined in the Russian Federation for three years at EIAV, 1,322 horses positively responding to AGID were found (0.1%). The largest number of sick horses was found in the constituent entities of the Siberian and Ural Federal Districts. Horses infected with the EIAV virus were found in all 12 constituent entities of the Siberian Federal District, 640 animals (0.1% of those examined). A tense epizootic situation has developed in the Omsk, Novosibirsk, Irkutsk and Tomsk regions, the Altai Republic, and the Trans-Baikal Territory. In 5 constituent entities of the Ural Federal District, horses responding positively to EIAV were found, only 584 samples (0.3%), the largest number — in the Sverdlovsk and Tyumen regions. Isolated cases of horse disease EIAV were registered in the Amur Region, the Sakha Republic and the Primorsky Territory of the Far Eastern Federal District, as well as in other regions of the country. Thus, the epizootic situation according to EIAV on the territory of individual constituent entities of the Russian Federation remains tense, which indicates the need for constant monitoring of the spread of infection.
