Tuberculosis (TB) is a dangerous disease caused by the bacterium Mycobacterium tuberculosis. Its transmission occurs through aerosols, making healthcare workers particularly vulnerable to it. At the San Cecilio Clinical University Hospital in Granada (HUCSC), preventive measures such as the use of personal protective equipment (PPE) and IGRA (interferon-gamma release assay) tests were implemented to detect latent tuberculosis infection. At HUCSC, between 2022 and 2024, 4.75% (92/1936) of workers were found to have positive IGRA test results, with no significant differences observed between professional categories. However, variability in positive IGRA rates was noted across different medical departments, with pulmonology and sample handling being the most affected. Additionally, a relationship was found between age and the likelihood of obtaining a positive IGRA test result. These findings underscore the importance of targeted preventive measures and a multifaceted approach to controlling and preventing tuberculosis in workplace environments.
