BACKGROUND
Mycetoma is a unique neglected tropical disease caused by a substantial number of different fungi or bacteria. Many of the disease's epidemiological characteristics are an enigma. Hence, understanding the spatial geographic distribution of mycetoma may clarify the association between the local environmental indicators, the spatial geographical distribution of mycetoma and its epidemiology.
METHODS
This study set out to determine the spatial geographical distribution of mycetoma in the Eastern Sennar locality, Sennar State, one of the highly endemic states in Sudan. It included 594 patients with confirmed mycetoma seen at the Mycetoma Research Centre, University of Khartoum, Khartoum, Sudan, from 1991 to 2020. The spatial geographical distribution of these mycetoma patients was studied. The study area geographic information system data, which included geological, soil, temperature and land cover details, were collected in different geographic information forms. Different geographical analytical techniques were used.
RESULTS
The patients' demographic characteristics were similar to those of the general characteristics of mycetoma patients in Sudan. Eumycetoma was the predominant type of mycetoma encountered in the studied patients. The data studied showed that most patients were located in the southern part of the locality along the Blue Nile river. The study showed an association between patients' spatial geographical distribution and soil types. Most patients' localities had light clay soil (475 patients [80%]), followed by sandy loam soil (79 [13%]) then loam soil (40 [6.71%]). Also, 85% of patients' localities had the same land cover and vegetation. There was no significant correlation between patients' localities with temperature or any other geological characteristic.
CONCLUSION
The present study showed certain associations between mycetoma spatial geographical distribution and certain environmental indicators. However, a further in-depth study to provide greater insight into the disease's epidemiological characteristics is needed.
背景
足菌肿是一种独特的被忽视热带病，由大量不同的真菌或细菌引起。该病的许多流行病学特征仍是未解之谜。因此，了解足菌肿的空间地理分布可能有助于阐明局部环境指标、足菌肿的空间地理分布及其流行病学之间的关系。
方法
本研究旨在确定苏丹高度流行州之一森纳尔州东森纳尔地区的足菌肿的空间地理分布。该研究包括 1991 年至 2020 年在苏丹喀土穆的喀土穆大学足菌肿研究中心就诊的 594 例确诊足菌肿患者。研究了这些足菌肿患者的空间地理分布。收集了包括地质、土壤、温度和土地覆盖详细信息在内的研究区域地理信息系统数据，并以不同的地理信息形式呈现。使用了不同的地理分析技术。
结果
患者的人口统计学特征与苏丹一般足菌肿患者的特征相似。外生菌肿是研究患者中主要的足菌肿类型。研究数据表明，大多数患者位于该地区南部沿青尼罗河。研究表明，患者的空间地理分布与土壤类型存在关联。大多数患者所在地区的土壤为浅色粘壤土（475 例[80%]），其次为砂壤土（79 例[13%]），然后是壤土（40 例[6.71%]）。此外，85%的患者所在地区具有相同的土地覆盖和植被。患者所在地的温度或任何其他地质特征与患者之间均无显著相关性。
结论
本研究表明，足菌肿的空间地理分布与某些环境指标之间存在一定的关联。然而，需要进一步深入研究以更深入地了解该疾病的流行病学特征。
