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.
