Tuberculosis and immigration.

Tuberculosis continues to be a major public health problem in Spain. The incidence of tuberculosis in the native population has declined steadily in recent years. Migration flows have changed drastically since the beginning of the 21st century, with Spain becoming a recipient country for immigrants. Because most of the immigrants comes from countries with high incidence of tuberculosis, the contribution of the migrant population to new cases of tuberculosis is higher in relative terms than its weight in the total population. Tuberculosis programs must address the cultural, economic and medical aspects of the disease, and particularly target groups at risk, including the migrant population. In this paper, we will review the epidemiology and dynamics of tuberculosis in the migrant population, their differentiating clinical characteristics and the programmatic actions to address the problem.
