The aim of this study was to determine the prevalence and to identify the risk factors associated with infection in pregnant individuals living in the Ponta de Pedras municipality, Marajó Archipelago, State of Pará, where an outbreak of toxoplasmosis occurred in 2013. From 2014 to March 2017, a cross-sectional study was conducted, including 555 pregnant individuals aged 13- to 42-years-old. Serological tests (enzyme immunoassays) were performed, and socioenvironmental and behavioral information were obtained through the application of a questionnaire. A prevalence of 68.3% was detected, and older age, having contact with soil and living in an urban area were the risk factors associated with seropositivity. The study confirmed the high prevalence of infection among pregnant individuals in the region. The association of the infection with the variables of residential area and contact with soil indicates that there was environmental contamination by oocysts in the municipality.
本研究的目的是确定帕拉州马拉若群岛蓬塔德佩德拉斯市感染弓形虫病疫情发生地的孕妇感染率，并识别与之相关的危险因素。2014年至2017年3月，开展了一项横断面研究，纳入了555名年龄在13至42岁之间的孕妇。进行了血清学检测（酶免疫测定），并通过问卷调查获取了社会环境和行为信息。检测发现感染率为68.3%，年龄较大、接触土壤和居住在城市地区是血清学阳性的相关危险因素。该研究证实了该地区孕妇感染率较高。感染与居住区域和接触土壤变量之间的关联表明，该市存在卵囊环境污染。
