Objective: The objective of the study was to describe the geographical coverage of Latin American and Caribbean scientific publications on tuberculosis and its international collaboration. Materials and methods: The records were retrieved from the PubMed database (2009-2018), limiting the search to Latin American and Caribbean countries. Articles were analyzed in several categories, such as the total number, countries, institutions, authors, collaborations, and citations. The software UCINET and VOSviewer were used. Results: 2,495 items were recovered, 4.2% of world production. More than half of the research came from Brazil (52.5%), Mexico (16.6%) and Peru (10.5%). 97.6% of the production is co-authored, with a rate of international collaboration of 24.5%. The countries with the highest production in international collaboration are Brazil (39.1%), Peru (26.8%) and Mexico (16%); they are also the countries with the best OutDegree, OutCloseness and Betweenness. The United States (11.9%), United Kingdom (5.8%), France (2.1%), Spain and Switzerland (1.7%), South Africa (1.7%) and Italy (1.6%) are the main collaborators with Latin America. Conclusion: Brazil, together with Peru and Mexico, is the undisputed leader in Latin American and Caribbean tuberculosis production, due to the volume of articles and its position in the collaborative network. The eradication of tuberculosis requires continuing research in international collaboration, to carry out more effective health policies on tuberculosis.
