Toxoplasmosis is an infection that is widespread in populations comprising humans and other warm-blooded creatures and is caused by the protozoan parasite called . Hence, knowledge of seroprevalence and associated risk factors is essential for planning adequate and efficient population health interventions. The objective of the present study was to evaluate the seropositivity of infection and to study the epidemiological indices in different categories of populations in East Azerbaijan Province, Iran.
This cross-sectional survey involved 426 participants 10 years of age and older from urban, rural, and nomadic areas. Serum samples were collected and analyzed for IgG antibodies against using the ELISA method. Demographic data, such as age, occupation, soil contact, and cat ownership, were collected through questionnaires.
The overall prevalence of toxoplasmosis was 62.2%, and a significant relationship between the infection and age, exposure to soil, and job involvement was observed. Farmers and ranchers had the highest occurrence rate of 69.4%; no association of the prevalence with gender, education, income, cat ownership, or eating habits was observed.
Occupational risk factors appear to play a significant role in the transmission of toxoplasmosis, although there is doubt cast on classic risk factors such as cat handling and ingesting contaminated foodstuffs. Such exposure can lead to risky transmission of ; therefore, continued surveillance and specific approaches in public health are needed to address such risks in the area.
弓形虫病是一种在包括人类和其他温血动物在内的人群中广泛传播的感染性疾病，由名为 的原生动物寄生虫引起。因此，了解血清阳性率及相关风险因素对于规划充分且有效的人群健康干预措施至关重要。本研究的目的是评估 感染的血清阳性率，并研究伊朗东阿塞拜疆省不同人群类别的流行病学指标。
这项横断面调查涉及来自城市、农村和游牧地区的426名10岁及以上的参与者。采集血清样本并使用酶联免疫吸附测定（ELISA）方法分析针对 的IgG抗体。通过问卷收集年龄、职业、接触土壤情况和养猫情况等人口统计学数据。
弓形虫病的总体患病率为62.2%，观察到感染与年龄、接触土壤和工作参与之间存在显著关系。农民和牧场主的发生率最高，为69.4%；未观察到患病率与性别、教育程度、收入、养猫情况或饮食习惯之间存在关联。
职业风险因素似乎在弓形虫病的传播中起重要作用，尽管对于诸如处理猫和摄入受污染食物等经典风险因素存在疑问。此类接触可导致 的危险传播；因此，需要持续监测并采取公共卫生方面的具体措施来应对该地区的此类风险。
