During the period 2013-2023, 917 cases of rabies among animals were registered in the Republic of Kazakhstan. Out of these, the number of cases in farm animals amounted to 515, in wild animals to 50 and in pets to 352. Data on rabies cases were obtained from the Committee for Veterinary Control and Supervision of Kazakhstan, as well as during expeditionary trips. This research was carried out to demonstrate the use of modern information and communication technologies, geospatial analysis technologies in particular, to identify and visualize spatio-temporal patterns of rabies emergence among different animal species in Kazakhstan. We also aimed to predict an expected number of cases next year based on time series analysis. Applying the 'space-time cube' technique to a time series representingcases from the three categories of animals at the district-level demonstrated a decreasing trend of incidence in most of the country over the study period. We estimated the expected number of rabies cases for 2024 using a random forest model based on the space-time cube in Arc-GIS. This type of model imposes only a few assumptions on the data and is useful when dealing with time series including complicated trends. The forecast showed that in most districts of Kazakhstan, a total of no more than one case of rabies should beexpected, with the exception of certain areas in the North and the East of the country, where the number of cases could reach three. The results of this research may be useful to the veterinary service in mapping the current epidemiological situation and in planning targeted vaccination campaigns among different categories of animals.
2013-2023 年期间,哈萨克斯坦共和国登记了 917 例动物狂犬病病例。其中,家畜动物病例数为 515 例,野生动物病例数为 50 例,宠物病例数为 352 例。狂犬病病例数据来自哈萨克斯坦兽医控制和监督委员会,以及考察旅行期间获得的数据。本研究旨在展示现代信息和通信技术的应用,特别是地理空间分析技术,以识别和可视化哈萨克斯坦不同动物物种狂犬病发病的时空模式。我们还旨在通过时间序列分析预测明年的预期病例数。应用“时空立方体”技术对代表三种动物类别的病例进行地区级时间序列分析,结果表明,在研究期间,该国大部分地区的发病率呈下降趋势。我们使用基于 Arc-GIS 时空立方体的随机森林模型估计了 2024 年狂犬病病例的预期数量。这种模型对数据的假设很少,在处理包含复杂趋势的时间序列时非常有用。预测结果表明,哈萨克斯坦大多数地区的狂犬病总病例数不应超过一例,该国北部和东部的某些地区除外,这些地区的病例数可能达到三例。本研究结果可能对兽医服务部门在绘制当前流行病学情况图以及规划不同类别动物的针对性疫苗接种运动方面具有一定参考价值。
