Toxocara spp. cause one of the most widespread soil-transmitted helminthic infections worldwide. In both developed and developing countries, soil contamination with Toxocara eggs is considered as a major threat to public health. A total of 515 soil samples from 89 sampling sites were collected from different locations of public health such as Wastelands and Streets, public parks, and marginal areas. The soil samples were examined for Toxocara eggs using a centrifugal-floatation technique utilizing a saturated sodium nitrate solution. centralization of positive soil samples in the province was studied by Spatial Statistics Techniques such as Average Nearest Neighbors and Spatial Autocorrelation and Kernel Density Function Toxocara spp. eggs were found in 94 (18.25 %) out of 515 samples collected from the studied areas. According to the results obtained, marginal areas are often contaminated with eggs of Toxocara. Consequently, preventive measures including health education should be implemented to reduce the potential risk of this parasitic infection.
弓首蛔虫属寄生虫引起的感染是全世界最广泛流行的土源性寄生虫感染之一。在发达国家和发展中国家，土壤受到蛔虫卵的污染被认为是对公众健康的主要威胁。从荒地和街道、公园和边缘地区等公共卫生的不同地点采集了 89 个采样点的总共 515 个土壤样本。使用饱和硝酸钠溶液的离心浮选技术检查土壤样本中是否存在蛔虫卵。通过平均最近邻和空间自相关以及核密度函数等空间统计技术研究了省内阳性土壤样本的集中情况。在从研究区域采集的 515 个样本中，有 94 个（18.25%）样本中发现了弓首蛔虫属寄生虫卵。根据所得结果，边缘地区通常受到蛔虫卵的污染。因此，应实施包括健康教育在内的预防措施，以降低这种寄生虫感染的潜在风险。
