Introduction

Toxocariasis is caused by nematodes of Toxocara genus, which infest dogs and cats, with humans serving as paratenic hosts.

Methods

The epidemiological profile of patients examined for toxocariasis between October 2014 and October 2019 at Evandro Chagas Institute (IEC) was outlined. The frequency of anti-T. canis IgG antibodies were evaluated using the Enzyme Linked Immunosorbent Assay (ELISA) method.

Results

From a total of 734 samples, 56% were from male (p < 0.05). Regarding age, the group with the most solicitations were from ≤11 years old individuals (p < 0.05). Pará state had the highest number of exams requested (92%), with the majority from residents of urban areas, accounting for 81.5% of samples (p < 0.05). The overall toxocariasis seroprevalence was 41.8%, the male sex being the most frequent with 60.9% (p < 0.05). The most affected age group was ≤11 years old, with a total of 67.8% of positive samples (p < 0.05).

Conclusion

The high rates obtained emphasize the need for complementary studies on toxocariasis in Brazil, especially in Pará state, contributing to epidemiological surveillance actions in the control of this infection. Besides, health campaigns for domestic and stray animals, also can contribute to a more effective surveillance in controlling parasitic infections and encourages the One Health approach.

2014 年至 2019 年在 Evandro Chagas 研究所 (IEC/SVSA/MS) 检查的患者中人类弓蛔虫病的流行病学概况

介绍

弓蛔虫病是由弓蛔虫属线虫引起的，这种线虫感染狗和猫，人类是寄生虫宿主。

方法

概述了 2014 年 10 月至 2019 年 10 月在埃万德罗查加斯研究所 (IEC) 接受弓蛔虫病检查的患者的流行病学概况。使用酶联免疫吸附测定（ELISA）方法评估抗犬毛虫IgG 抗体的频率。

结果

在总共 734 个样本中，56% 来自男性 (p < 0.05)。就年龄而言，请求最多的群体来自 ≤11 岁的个体 (p < 0.05)。帕拉州的考试请求数量最多（92%），其中大部分来自城市地区居民，占样本的 81.5%（p < 0.05）。总体弓蛔虫病血清阳性率为 41.8%，其中男性最为常见，为 60.9%（p < 0.05）。受影响最大的年龄组是≤11岁，阳性样本总数为67.8%（p < 0.05）。

结论

获得的高比率强调需要对巴西，特别是帕拉州的弓蛔虫病进行补充研究，有助于控制这种感染的流行病学监测行动。此外，针对家养动物和流浪动物的健康运动也有助于更有效地监测控制寄生虫感染，并鼓励“同一个健康”方法。
