In 2017, the World Health Organization estimated 460 000 cases of MDR-TB, of which 8.5% were also extensively drug-resistant (XDR) cases [1]. In Portugal, over the last decade, the decreasing tendency of TB cases is about 7% per year, and the proportion of MDR-TB cases remains steadily around 1% of the total TB cases. In 2017, the preliminary report of the Portuguese national TB programme reported 1607 new cases of pulmonary TB, with 12 MDR-TB cases [2].Analysis of MDR-TB rates showed consistent decreases in cases and clustering rates but did not establish valid relationships with the epidemiological information collected by the public health authorities http://ow.ly/3BnN30nxqW3 ER -
