Caused by the parasitic nematodes and , toxocariasis in humans can result in covert toxocariasis, ocular toxocariasis, visceral larval migrans, and neurotoxocariasis. A common infection, toxocariasis exposure varies widely within and between countries, with a previous estimate of seroprevalence using data from 1988 to 1994 in the United States of approximately 13%. Age, poverty, sex, educational attainment, ethnicity, and region have been associated with seroprevalence. In this study, we sought to determine the seroprevalence of and factors associated with seropositivity in the United States using data from the National Health and Nutrition Examination Survey from 2011 to 2014 to provide a more recent estimate of seroprevalence in the United States. We found an overall seroprevalence of 5.1%. Increasing age, male sex, low educational attainment, low income, and immigration status each was associated with seropositivity. Mexican Americans had reduced odds of exposure. These findings show that exposure to continues in the United States and that several demographic factors influence the risk of exposure.
由寄生线虫和引起的人类弓蛔虫病可导致隐性弓蛔虫病、眼弓蛔虫病、内脏幼虫移行症和神经弓蛔虫病。弓蛔虫病是一种常见感染，在不同国家内部和之间，弓蛔虫病的暴露情况差异很大，根据1988年至1994年美国的数据，此前估计血清阳性率约为13%。年龄、贫困、性别、教育程度、种族和地区都与血清阳性率有关。在本研究中，我们试图利用2011年至2014年美国国家健康和营养检查调查的数据，确定美国弓蛔虫病的血清阳性率以及与血清阳性相关的因素，以提供美国弓蛔虫病血清阳性率的最新估计。我们发现总体血清阳性率为5.1%。年龄增长、男性、低教育程度、低收入和移民身份均与血清阳性有关。墨西哥裔美国人接触的几率降低。这些发现表明，在美国，人们仍持续接触弓蛔虫，并且一些人口统计学因素会影响接触风险。
