Abstract

Background: Toxoplasmosis is one of the most common parasitic infections worldwide with varying prevalence between human populations. These variations are mainly associated with human exposure to risk factors. In this article, the seroprevalence of Toxoplasma gondii infection and the risk factors associated with infection in 1729 blood donors from São José do Rio Preto, São Paulo, Brazil were analysed.

Methods: The serological tests for detecting immunoglobulin M (IgM) and immunoglobulin G (IgG) anti-T. gondii were used. The risk factors associated with the infection were identified through the application of an epidemiological questionnaire.

Results: The prevalence of T. gondii infection was 48.0%. The following factors were identified in the final model after multiple logistic regression analysis: drinking raw milk (p=0.003; odds ratio [OR] 1.364 [confidence interval {CI} 1.1 to 1.7]), residing in a rural area (p<0.0001; OR 2.764 [CI 1.7 to 4.6]) and receiving a blood transfusion (p=0.015; OR 1.856 [CI 1.1 to 3.0]).

Conclusions: The data obtained in this study showed that the blood donor population is exposed to risk factors related to infection by T. gondii. These data allow the establishment of control programs to contribute to public health in northwestern São Paulo state.

巴西圣保罗州西北部地区献血者感染弓形虫的血清流行病学。

背景：弓形虫病是全球最常见的寄生虫感染之一，不同人群的发病率各不相同。这些差异主要与人类暴露于风险因素有关。本文分析了巴西圣保罗州圣若泽杜里约普雷图 1729 名献血者的弓形虫感染血清流行率以及与感染相关的风险因素：方法：采用血清学检测方法检测抗弓形虫免疫球蛋白 M (IgM) 和免疫球蛋白 G (IgG)。通过流行病学问卷调查确定了与感染相关的风险因素：结果：淋病双球菌感染率为 48.0%。结果：淋病双球菌感染率为 48.0%，在多重逻辑回归分析后的最终模型中确定了以下因素：饮用生牛奶（p=0.003；几率比[OR]1.364[置信区间{CI}1.1 至 1.7]）、居住在农村地区（pCI）：本研究获得的数据表明，献血人群存在感染淋病双球菌的风险因素。这些数据有助于制定控制计划，为圣保罗州西北部的公共卫生做出贡献。
