Plague of small ruminants (PSR) causes enormous economic damage to sheep and goat breeding. Mortality and lethality rates reach 100% of the total number of sick animals. The main materials for recording and analyzing the epizootic situation in foreign countries were: statistical data from the OIE yearbooks for 2007–2019. Cartographic data analysis was carried out using software known on the market for geographic information systems, QGIS, ArcGIS Decktop 10.4. A retrospective cartographic analysis of the epizootic situation of plague of small ruminants in the world in 2007–2019 showed that in 2017 the infection was registered in Mongolia (4 outbreaks, 1661 cases), in Israel (2 outbreaks, 34 cases), in China (2 outbreaks, 288 cases). In 2018, plague of small ruminants was registered in 7 countries of the world: Algeria, Bhutan, Bulgaria, Burundi, China, Israel, Sierra Leone. Algeria reported 6 outbreaks and 30 cases, Bhutan 1 outbreak and 1 case, Bulgaria 7 outbreaks, 28 cases, Burundi 8 outbreaks, 7395 cases, China 6 outbreaks, 1,757 cases, Israel 3 outbreaks, 560 cases , Sierra Leone – 7 outbreaks, 649 cases. As of December 2019, there were 10 outbreaks and 208 cases of small ruminants’ plague of in Israel, 99 outbreaks in Algeria and 3,139 cases, as well as 1 outbreak and 179 cases in Libya. By the retrospective analysis, it has been established that the nosoarea of the PSR pathogen is extremely widespread in many continents of the world.

According to OIE and FAO data in 2009-2019, there have been 2,884 outbreaks of plague of small ruminants (PPR) worldwide, mainly in Africa and Asia. Mortality from this pathology reaches 100 %. The economic damage caused by this disease to animal husbandry consists of a mass mortality, a decrease in the productivity of sick animals and the cost of quarantine measures in a disadvantaged area. Cartographic analysis showed that the highest concentration of PPR outbreaks for the indicated period was observed in five main regions. Northwest Africa (includes Morocco, Algeria and Tunisia); The Black Sea coast of Bulgaria; Eastern coast of the Mediterranean Sea (Israel); People’s Republic of Bangladesh; Southern, Southeastern and Eastern parts of the People’s Republic of China. Outbreaks with the largest number of dead animals were concentrated mainly in Bangladesh and China. Outbreaks with the largest number of dead animals were concentrated mainly in Bangladesh and China, where vaccinations have not been carried out in recent years. The study of the correlation between the PPR incidence rate and the number of animals immunized in the most disadvantaged states found only modest reductions in incidence as a result of vaccination campaigns. Pearson’s correlation coefficient was - 0.13 for Algeria, - 0.19 for Bangladesh and - 0.33 for Israel, which appears to be due to the small scale of vaccination campaigns. The obtained results of the epizootic analysis by PPR indicate insufficient coverage of animals susceptible to the pathogen by vaccination and a greater likelihood of new outbreaks of the disease not only in disadvantaged countries, but also the spread of infection in new territories.
