BACKGROUND: The Chilean Program for the Control and Elimination of Tuberculosis (PROCET) has reduced mortality from this disease by 78% between 2004 and 2013. However, after decades of successful results, starting in 2000 there was a slowdown in the reduction of incidence and since 2014, an increase in it. AIM: To describe the socio-epidemiological evolution of tuberculosis (TB) cases treated at health clinics in the Metropolitan Region (MR) of Chile from 2005 to 2018, stratifying by country of origin. METHODS: Cross-sectional study with ecological components, including analyses of age, sex, TB localization, bacteriological confirmation of diagnosis, co-infection with HIV, incarceration, country of origin, and effectiveness of tuberculosis treatment. RESULTS: A total of 7,507 TB cases were recorded during the study period; 75.1% of cases were pulmonary tuberculosis, and 65.4% were bacteriologically confirmed. Overall, 19.0% of cases involved persons born outside of Chile, with the proportion of cases in foreign-born persons increasing over the past 6 years. Incidence decreased during the first half of the study period but then began to increase after 2012, moving the country away from the threshold of elimination. A total of 74.3% of cases were treated successfully, and 13.4% expired. CONCLUSION: In recent years, TB incidence has increased in the MR of Chile, possibly attributable to growing populations of vulnerable groups such as immigrants. This finding suggests an urgent need to implement and reinforce strategies such as education, an active screening model and more efficient contact tracing to prevent the spread of TB.
