Association between tuberculosis/HIV co-infection and closure status in children under 18 years of age

ABSTRACT Objective: To analyze the epidemiological profile of cases of tuberculosis/human immunodeficiency virus co-infection in children under 18 years of age associated with the closure situation in the state of Paraná, Brazil. Method: Cross-sectional study of notified cases of tuberculosis/human immunodeficiency virus co-infection from 2002 to 2022. Descriptive analysis, incidence rate and chi-square test were carried out. Results: 62 cases of co-infection were recorded with instability in the number of cases and the incidence rate per year, with an increase in (0.29) 2003-2004, (0.18 to 0.25) 2008-2010, (0.18 to 0.11) 2012-2014 and (0.07) 2016-2017, and a decline in cases between (0.04) 2020-2021. There were no confirmed cases between 2018, 2019 and 2022. The majority of cases occurred in the adolescent age group, followed by the school age group. There was statistical significance for the urban area (p=0.013). Conclusion: These findings, in addition to providing a warning, can incorporate planning for the control of co-infection.
