Unveiling the Zoonotic Significance of Toxocariasis in Humans: The Role of Toxocara canis

Toxocariasis is a zoonotic disease caused by the parasite Toxocara canis, with significant effects on human health. This article provided a comprehensive overview of the importance of complications of Toxocara canis infection. The introduction highlighted the relevance of zoonotic diseases and introduced toxocariasis as a specific example. The subsequent sections delved into toxocariasis, covering its transmission, lifecycle, host specificity, and primary sources of human infection. The epidemiology section presented the global prevalence and distribution of toxocariasis at 11.1% (95% CI: 10.6–11.7%), emphasizing high-risk groups and geographical factors contributing to illness. Detailed information was provided regarding the clinical manifestations of toxocariasis, including variations in disease severity and potential complications. Symptoms of visceral toxocariasis include fever, fatigue, coughing, wheezing, or abdominal pain. The diagnostic methods include laboratory methods (serological testing and western blot) and molecular techniques (PCR), and clinical methods (chest X-ray and CT scan). The prevention and control section outlined strategies for prevention, highlighting the significance of public health measures and awareness campaigns. The One Health approach has recognized the interconnections between human, animal, and environmental health. It has highlighted the necessity of cooperative actions to prevent the spread of diseases that can be transmitted between animals and humans. Future directions need to highlight ongoing research and advancements, including improved diagnostic tools, targeted therapies, risk assessment, and international collaboration. The conclusion reinforces the importance of understanding and addressing Toxocara canis infection on human health. Adopting a One Health approach and implementing effective prevention, diagnosis, and treatment strategies can reduce the burden of toxocariasis, leading to improved health outcomes for humans and animals.
