Toxocariasis is a zoonotic disease, which is transmitted to humans from swallowing larvae of the two species Toxocara canis and Toxocara cati. The larvae can parasite on bodily organs such as brain, eyes, liver, and lungs ; and can cause serious symptoms such as epilepsy, vision impairment or even blindness. Toxocariais is distributed from Southern hemisphere to tropical countries, with different prevalence, from 0.7% in New Zealand to 93.0% in La Reunion (Africa). In Viet Nam, the increase in the infection of the disease in recent years has caused negative impact on the health of the community. However, little has been known of the studies on the current situation of toxocariasis, as well as the associated factors of the disease. In addition, no appropriate control measures have been in place to be applied in to the community level. This study was conducted as a contribution to seek for the understanding of the distribution and associated factors of toxocariasis, and to propose timely and appropriate intervention measures, so as to help reduce the incidence in the community
