Abstract

Toxocarosis remains an important neglected parasitic infection representing one of the most common zoonotic infections caused by the parasite Toxocara canis or less frequently by Toxocara cati. The epidemiology of the disease is complex due to its transmission route by accidental ingestion of embryonated Toxocara eggs or larvae from tissues from domestic or wild paratenic hosts. Even though Toxocara infects about 1,4 billion people worldwide, global epidemiological data regarding the relationship between seropositivity and toxocarosis is limited. Although the vast majority of the infected individuals remains asymptomatic or experiences a mild disease, the infection is associated with important health and socioeconomic consequences, particularly in underprivileged, tropical, and subtropical areas. Toxocarosis is a disease with multiple clinical presentations, which are classified into five distinct forms: the classical visceral larva migrans, ocular toxocarosis, common toxocarosis, covert toxocarosis, and cerebral toxocarosis or neurotoxocarosis. Anthelmintic agents as for example albendazole or mebendazole is the recommended treatment, whereas a combination with topical or systemic corticosteroids for specific forms is suggested. Prevention strategies include educational programs, behavioural and hygienic changes, enhancement of the role of veterinarians, and anthelmintic regimens to control active infections.
