Dear Chief Editor,The migratory phenomenon in Latin America has significantly increased in recent decades, especially in Brazil and Chile. The frequent vulnerability of many of these migrants constitutes a major concern related to potential risks of emerging and re-emerging diseases. This is due to the poverty situation and the lack of resources for public health care, and current imported cases of measles from Venezuela are a major example of this social burden. Imported cases may increase the challenges related to the control of transmissible infections. In this scenery, pulmonary tuberculosis plays a main role among the communicable diseases. Chilean authors have properly suggested the utilization of basic screening of tuberculosis in migrants from countries of elevated prevalence, aiming to employ early treatment and to prevent infections associated with late diagnosis of an index case (Alarcón & Balcells, 2017).
