The seroprevalence of cysticercosis indicate that there is a high risk of contact with Taenia solium in Mexico, including both genders and all regions, socioeconomic group, and ages. There are some statistically significant differences in risk of contact, affecting principally the center and southeast of the country, rural areas, handicapped persons, children, old people and women. However, these differences are small. This study emphasizes the fact that the risks of infection by Taenia solium are important in all groups, and therefore, the programs for the control of this disease should be focused at the entire population and emphasize strategies for social development.
