Toxocariasis is a worldwide-distributed helminth parasitic infection. This study aimed to evaluate the seroprevalence of human toxocariasis in children living in Ardabil Province, North-West of Iran.
A seroepidemiological study to evaluate human toxocariasis among urban and rural populations of Ardabil County, North-West of Iran using ELISA test was carried out from 2019 to 2020. The study population was 472 children (185 females and 287 males) aged between 5 and 15 yr old. Immunoglobulin G antibodies against spp. were analyzed by ELISA test.
Of the 472 collected serum samples, 66 (14.0%) were positive for antibodies against human toxocariasis. The highest prevalence of infection was observed in children with age groups of 5-6 years. Data demonstrate higher seroprevalence among males (15.3%) than females (11.8%). Rural areas prevalence was significantly higher (24.4%) than the urban area (8.65%). The rate of the diseases was 22.8% in children having history of contact with dog.
Toxocariasis is prevalent in the children of Ardabil region. The present study can increase the awareness of the population about the risk of zoonotic diseases as well as the anthelmintic treatment of dogs by veterinarians and, more importantly, the control of stray dogs.
弓蛔虫病是一种在全球范围内传播的蠕虫寄生虫感染。本研究旨在评估伊朗西北部阿尔达比勒省儿童人群中人体弓蛔虫病的血清流行率。
2019年至2020年,采用酶联免疫吸附测定(ELISA)试验,对伊朗西北部阿尔达比勒县城乡人口中的人体弓蛔虫病进行血清流行病学研究。研究对象为472名年龄在5至15岁之间的儿童(185名女性和287名男性)。通过ELISA试验分析针对弓蛔虫属的免疫球蛋白G抗体。
在收集的472份血清样本中,66份(14.0%)人体弓蛔虫病抗体呈阳性。感染率最高的是5至6岁年龄组的儿童。数据显示男性(15.3%)的血清流行率高于女性(11.8%)。农村地区的流行率(24.4%)显著高于城市地区(8.65%)。有接触狗史的儿童中该病发病率为22.8%。
弓蛔虫病在阿尔达比勒地区的儿童中普遍存在。本研究可以提高人们对人畜共患疾病风险的认识,以及兽医对狗进行驱虫治疗的意识,更重要的是,可以加强对流浪狗的管控。
