Abstract
To determine whether increased migration is associated with an increase in incidence of toxocariasis (visceral larva migrans), we analyzed clinical data obtained from immigrants from Latin America. Although infection with Toxocara sp. roundworm larvae is distributed worldwide, seroprevalence is highest in tropical and subtropical areas.

Human toxocariasis is a zoonosis caused by the larvae of Toxocara sp. roundworms. Although distribution is worldwide, seroprevalence is highest in tropical countries, including in Latin America. Immigration from tropical areas to Europe continues to increase, with Spain a frequent destination. Data on visceral larva migrans (VLM) among immigrants from Latin America in western countries (primarily European countries, the United States, and Canada) are scarce. To determine whether increased migration is associated with increased VLM incidence, we analyzed clinical and epidemiologic data from immigrants from Latin America.
