Contacts received the tuberculin skin test and\/or interferon gamma release assay and it was determined whether they had TB or LTBI. Variables associated with TB or LTBI in contacts (study period and sociodemographic variables) were analyzed using adjusted odds ratio (aOR) and the 95% confidence intervals (95% CI).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The pre-pandemic and pandemic periods showed, respectively: 503 and 255 pulmonary TB reported cases (reduction of 50.7%); and 4676 and 1687 contacts studied (reduction of 36.1%). In these periods, the proportion of TB cases among the contacts was 1.9% (84\/4307) and 2.2% (30\/1381) (P\u2009=\u20090.608); and the proportion of LTBI was 25.3% (1090\/4307) and 29.2% (403\/1381) (P\u2009&amp;lt;\u20090.001). The pandemic period was associated to higher LTBI proportion (aOR\u2009=\u20091.3; 95% CI 1.1\u20131.5), taking into account the effect on LTBI of the other variables studied as sex, age, household contact and migrant status.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>COVID-19 is affecting TB control due to less exhaustive TB and LTBI case detection.
