This study was aimed to understand the spatial and seasonal epidemiology of Newcastle disease (ND) in Türkiye using the outbreak data between 2017-2019 and also to calculate the case-fatality rates of this disease. It was also aimed to produce the maps by using Geographical Information Systems (GIS). Data were obtained from the World Animal Health Information System (WAHIS) database of the World Organization for Animal Health (OIE). Total number of 220 outbreaks of ND were registered in 47 provinces of Türkiye between this years. Accordingly, 88,372 poultry birds transmitted the disease. The highest number of ND outbreaks, cases and deaths was reported in The Black Sea Region. According to the regions there was a statistically significant difference in the number of outbreaks (P<0.05), but there was no statistically significant difference in terms of cases and deaths (P>0.05). On the other hand the highest number of ND outbreaks, cases and deaths was reported in the spring season. As a result of the comparisons according to the seasons, there was a statistically significant difference in the number of deaths (P<0.05), but there was no statistically significant difference in terms of outbreaks and cases (P>0.05). The spatial and seasonal distributions identified in this study should be taken into account while attempting to control the disease. Also, it is thought that the creation of spatial maps based on ND outbreaks that are common in Türkiye will contribute to the determination of the areas where precautions should be taken against the disease.
